Linear Regression following Sentdex's tutorials

Hello. I am trying to do some machine learning on some bitcoin data, specifically linear regression. The full code is here, but in order to plot it on a graph, I want to use the values of y (which is the values of x in 14.5 days time, so price in 14.5 days time) where I use the old actual values of y followed by the new values of y which are the predictions. In order to do this I need to find the values of X which have values for y (the predictions) and the values for x which already have the price in 14.5 days time. I performed a shift on the data, meaning some Xs have values for Y in 14.5 days time and some don't.
Why 14.5 days? As the data set is 1450 days long and I did a 0.01 negative shift. Hopefully I communicated what I was trying to say alright.
import pandas as pd import math import numpy as np from sklearn import preprocessing, svm from sklearn.model_selection import cross_validate from sklearn.model_selection import train_test_split from sklearn.linear_model import LinearRegression from statistics import mean import matplotlib.pyplot as plt from matplotlib import style df = pd.read_csv("coinbaseUSD_1-min_data_2014-12-01_to_2019-01-09.csv") df['date'] = pd.to_datetime(df['Timestamp'],unit='s').dt.date print("calculating...") forecast_col = 'Weighted_Price' forecast_out = int(math.ceil(0.01*len(df))) #forecast_out = 20998 = 20998 minutes = 14.5 days df['label'] = df[forecast_col].shift(-forecast_out) df = df[['date', 'Weighted_Price', 'label']] df.dropna(inplace=True) X = np.array(df['Weighted_Price'], dtype = np.float64) y = np.array(df['label'], dtype=np.float64) X_lately = X[-forecast_out:] X = X[:-forecast_out:] def best_fit_line(X, y): m = (((mean(X) * mean(y)) - mean(X*y)) / ((mean(X) * mean(X)) - mean(X*X))) c = mean(y) - (m * (mean(X))) return m, c m, c = best_fit_line(X, y) print(m, c) regression_line = [(m*values) for values in X] plt.scatter(X, y) plt.plot(X, regression_line) plt.show()

So what have I tried? The offender is this line here:
X_lately = X[-forecast_out:] X = X[:-forecast_out:]
That is what sentdex did in the video series, but I get the error: ValueError: operands could not be broadcast together with shapes (1871868,) (1892866,)
This doesn't work with:
m = (((mean(X) * mean(y)) - mean(X*y)) / ((mean(X) * mean(X)) - mean(X*X)))
due to this making the X and Ys different lengths? I'm not sure.
What am I doing wrong?

Welcome to the /Bitcoin Sticky FAQ

You've probably been hearing a lot about Bitcoin recently and are wondering what's the big deal? Most of your questions should be answered by the resources below but if you have additional questions feel free to ask them in the comments.
The following videos are a good starting point for understanding how bitcoin works and a little about its long term potential:
For some more great introductory videos check out Andreas Antonopoulos's YouTube playlists, he is probably the best bitcoin educator out there today. Also have to give mention to James D'Angelo's Bitcoin 101 Blackboard series. Lots of additional video resources can be found at the videos wiki page or /BitcoinTV.
Key properties of bitcoin
Some excellent writing on Bitcoin's value proposition and future can be found here. Bitcoin statistics can be found here, here and here. Developer resources can be found here and here. Peer-reviewed research papers can be found here. The number of times Bitcoin was declared dead by the media can be found here. Scaling resources here, and of course the whitepaper that started it all.

Where can I buy bitcoins?

BuyBitcoinWorldwide.com and Howtobuybitcoin.io are helpful sites for beginners. You can buy or sell any amount of bitcoin and there are several easy methods to purchase bitcoin with cash, credit card or bank transfer.

Unlike traditional markets, bitcoin markets operate 24 hours per day, 365 days per year. Preev is a useful site that that shows how much various denominations of bitcoin are worth in different currencies. Alternatively you can just Google "1 bitcoin in (your local currency)".

Securing your bitcoins

With bitcoin you can "Be your own bank" and personally secure your bitcoins OR you can use third party companies aka "Bitcoin banks" which will hold the bitcoins for you.

I tried to mine some Bitcoins and I think I might have unglued the fabric of the universe.

A little help?
I’m a research assistant working at a science facility in China. We’ve got one of the most powerful supercomputers in the world. We had to power it down a few months back to do some upgrades, and we’ve got a skeleton crew until it’s all done. Last night, my friend Chen and I were the only ones on the overnight shift. The majority of the hardware was up and running and we were supposed to be stress testing the nodes.
We had software we were required to run, but I had the bright idea to mine Bitcoins to test it instead. God knows those calculations can stress your hardware.
It didn’t take much convincing to get Chen on board with the idea. If we could make a little extra money on the side from our endeavor, it was that much better. Besides, we could run the regular software after.
Chen downloaded the blockchain, installed everything, and we started processing. Lo and behold, BTC fractions started rolling in. It was way faster than either of us had expected. After an hour, we’d made a couple hundred USD. This supercomputer is something else. Adiabatic quantum emulation, baby. Not quite full QC, but close enough where it matters. When the upgrades go public, you’ll know what I’m talking about.
All that said...I think we fucked something up.
We were well on our way to our first thousand USD when Chen noticed one of the temperature gauges on a series of node clusters had reached a critical level. Now, each node is set to shut down automatically if anything is running in a manner that might damage the hardware. When stress testing, it’s expected that temperatures will get high enough to cause warnings.
The weird thing was, the warning wasn’t because the temperature was too high. It was too low.
We both looked at the screen with a good deal of confusion. All the nodes were pegging near their maximum temperatures except a cluster in the very rear corner of the football-field-sized room.
“Are those nodes on?” I asked Chen.
He nodded. “Yeah, they’re doing just as much work as all the other ones. They should be hot.”
“Maybe the gauges are fucked?”
“Maybe. I’ll go take a look.”
Chen grabbed a walkie-talkie and started the long walk from the office to the far-end of the supercomputer room.
I watched the screen readouts with interest. The temperature in that area kept dropping. Another few degrees and the nodes would power down.
“It’s fuckin freezing in here,” Chen complained over the walkie-talkie.
“You worked in a datacenter for six years, retard,” I replied. “You know it’s supposed to be cold.”
“I know, dick. But this is different. Like I think something’s really wrong. There’s frost on the floor.”
I took another look at the readouts. Despite the supercomputer operating at 99.997% capacity, all the temperature gauges had started to drop. A flash of red showed up on screen. The first nodes to be affected by the cold had shut down.
“Keung, you need to come in here,” Chen said.
“Why, what’s up?”
“Just come see. And shut down the mining for a minute.” Chen paused. “And bring your jacket.”
I gazed lustfully at the BTC readout. $2443 already. I sighed and hit pause. I went to grab my jacket and decided against it. I wanted to call Chen a pussy for being cold.
After three steps into the supercomputer room, I realized Chen was not a pussy. Or that we both were pussies. Either way, it was fucking freezing in there.
“Holy shit!” Chen yelled.
I broke into a jog and met him on the far end of the cavernous room.
“What?” I asked. I shivered and balled my fists under my armpits.
Chen pointed. I followed his finger with my eyes and squinted to see better in the dimness. It took a second, but then I saw it. Hugging the wall around the corner from a server rack was...well...a hole.
“What the fuck?” I muttered. I took a step closer. The cold was borderline unbearable. It was definitely coming from the bizarre opening. Frigid wind washed over us and forced us to step back.
On the other side of the hole, there was gray, stony ground and pitch black sky dotted with stars.
“What did we just do?” Chen asked.
“Did we cause this to happen?” I replied. “Like what the fuck is going on?”
The hole was closing. I think Chen was about to respond, but before he could, some...thing... emerged from the hole.
We both shrieked and leapt back. Chen fell into the back of one of the racks and I heard a piece of equipment snap. I didn’t care about that. My eyes were trained on whatever had just come out.
It was dull red and shaped like, oh hell, I don’t know, a mix between a pineapple and a crocodile with eye stalks all over its back.
Chen and I, our breaths held, tried to back away to avoid its attention. The creature’s eye stalks waved around in the air, as if trying to figure out what had happened. Behind it, the hole closed.
I grabbed the back of Chen’s shirt and pulled him to his feet. The thing’s stalks fixated on us. We stopped moving. It took a few steps in our direction on its six, pointy legs. Then it leapt forward. Onto Chen.
Chen made a sound I’d only previously associated with cats fighting for their lives. He grasped the dog-sized thing and pushed it away. It crashed into a rack of machines.
I pulled Chen away and we ran as fast as we could back to the control room. Despite my terror-induced tunnel vision, I didn’t fail to notice another hole in supercomputer room. This time in the ceiling. And another one of those things was coming out of it.
Once we were out, we had no idea what to do. Chen wanted to call the head of the supercomputing project but I talked him out of it. That guy had connections to the Party and, technically, the whole project is a government-run operation. We’d be fucked beyond fucked.
I helped bandage Chen’s wounds. Every so often, we’d catch a glimpse of one of the creatures in the monitors overlooking the supercomputer room.
After a discussion, Chen and I left without telling anyone what we'd done. We didn’t go home because we knew people would be looking for us as soon as they discovered what had happened. We got in his car and drove for hours.
Now we’re sitting in an internet cafe. The scratches on his hands and arms aren’t closing up. They’re getting puffy and itchy. He just told me he thinks he felt something move under his skin.
Our phones wouldn’t stop ringing before I pulled out the SIMs and flushed them. Now we’re stuck here and we don’t know what to do. To say I’m concerned is a bit of an understatement. I’d really love some advice.

Bitcoin Units

One Bitcoin is quite large (hundreds of £/$/€) so people often deal in smaller units. The most common subunits are listed below:
Unit Symbol Value Info
millibitcoin mBTC 1,000 per bitcoin SI unit for milli i.e. millilitre (mL) or millimetre (mm)
microbitcoin μBTC 1,000,000 per bitcoin SI unit for micro i.e microlitre (μL) or micrometre (μm)
bit bit 1,000,000 per bitcoin Colloquial "slang" term for microbitcoin
satoshi sat 100,000,000 per bitcoin Smallest unit in bitcoin, named after the inventor
For example, assuming an arbitrary exchange rate of $500 for one Bitcoin, a $10 meal would equal:

Changelly vs ShapeShift

Instant exchange is a popular way to trade cryptocurrencies quickly and efficiently. In our next few articles, we will try to compare and evaluate the most popular exchangers at the moment.
Today, Changelly and ShapeShift are still pretty popular services for these purposes. However, before using this or that exchanger, each cryptocurrency trader needs to weigh all the pros and cons.
In this comparative review, we compare Changelly ShapeShift and go through some of their key similarities and differences, according to the safety criteria, the commission, options for different cryptocurrencies and the user interface.
User interface
First, let's look at a couple of Changelly and ShapeShift in terms of user interface. This is the first impression that a trader who uses an exchanger gets.
Changelly interface is one of the most straightforward and easy-to-use interfaces among all cryptocurrency exchangers. For example, on Changelly you do not need to go to a new page to look at the trading options and calculate the exchange rate: all this information is at the top of the main page. Naturally, before you participate in the auction you will have to register. In addition, for their services, Changelly can sometimes take a significant commission.
Previously, ShapeShift exchanger was known as an exchanger without accounts. However, in September 2018, the developers decided to change the model of the platform to give users additional protection and reduce friction. Now, to trade on ShapeShift, you will have to register.
Compared to Changelly, for beginners, ShapeShift may seems more complicated exchanger. On its main page, a pop-up window "account required to participate in the auction" appears, which also describes all the advantages. After closing this window, you will find yourself on the statistics page, where you can see a variety of indicators. For example, you can look at recent transactions. Also on the homepage there is a 24-hour statistics of the number of transactions and BTC volume, the average order processing time and the most popular trading pairs.
Security
On its website Changelly stores no user funds. Instead, the exchanger sends funds directly to your wallet. It makes Changelly, not the custodian exchanger, which is usually safer than a conventional exchange, which holds users' funds. In addition, Changelly uses two-factor authentication (2FA).
In May 2017, one of Changelly's supporting accounts was hacked. Some users received the following message: "All customers who make an exchange from Bitcoin to another currency must manually transfer to the specified Bitcoin address:...". However, Changelly support immediately blocked this account.
ShapeShift, in turn, once used hot wallets on its website. It is unclear whether they can be used now, but users still remember the past vulnerability of the platform. In April 2016, ShapeShift exchanger was hacked and lost $200,000. Here's a comment from CEO Eric Voorhees himself: "the server Infrastructure was compromised and was under serious threat. We decided to quickly wipe out this infrastructure and build a completely new and secure environment." It is important to note that in the course of this, no customer has lost their money. The only funds lost belonged to the company itself. ShapeShift representatives called their own employee responsible for the incident.
Commissions
ShapeShift has quite a good commission for an instant exchanger. For each transaction, they take only a commission for mining. Some argue that this commission is somewhat overstated compared to the standard commission on mining, on which the platform earns. Anyway, for one transaction you will pay no more than 0.5 %.
ShapeShift does not return funds after failed transactions if the amount of lost assets is less than the mining commission. If you sent the cryptocurrency to the wrong address (for example, to GNT instead of ETH address), the platform will charge you a refund fee in the equivalent of 50 euros at the current rate.
As in ShapeShift, Changelly’s commission is approximately 0.5 %. However, many Changelly users notice that the exchanger has "hidden fees", but basically it isn’t, it is a result of high rate volatility of cryptocurrencies. For example, when you enter your existing funds (for example, USD), the amount transferred to another currency (for example, BTC) may differ from the current rate. And sometimes the resulting amount is the same as specified on the exchange. This should be taken into account when trading if you do not want to lose a small part of your funds. Although you should do this all the time in all exchangers.
The choice of currencies
Of course, the main advantage of both ShapeShift and Changelly is the variety of trading pairs. For example, you can easily exchange Qtum to Aragon directly instead of first changing Qtum to Bitcoin and then Bitcoin to Aragon, as is required on most other platforms.
If we talk about the most obvious differences between Changelly and ShapeShift, it is worth considering the availability of exchange to the ordinary money. In the exchanger ShapeShift there is not a single fiat currency. Instead, ShapeShift collaborates with Simplex to provide its users with this capability. However, even considering this partnership, your choice is limited to BTC-USD and BTC-EUR trading pairs.
About 33 cryptocurrencies are available on ShapeShift. There are several other cryptocurrencies marked as "temporarily unavailable", which may limit the use of the platform for some users. On the other hand, Changelly offers a large selection of trading crypto pairs (over 90) for USD and EUR. Also, this exchanger allows the use of debit and credit cards (Visa or Mastercard).
Geographic and transaction limits
ShapeShift and Changelly doesn’t have any restrictions at the place of stay. Users from all over the world are free to use both projects. This is good news, especially given the fact that now many exchanges can not boast of such accessibility.
If you are going to change large amounts, you need to take into account that each exchanger has its own limitations. ShapeShift has a relatively low transaction limit of $10,000 for level 1 users. By participating in the exchange, you can extend these limits. As of November 2018, higher levels (2-5) are not available to those who are not members of the community. The maximum limits of Changelly are from $ 50 to $ 10 000 for the first transaction, up to $ 20 000 per day and up to $ 50 000 per month.
Conclusion
So which exchanger, after all, is better? Having studied all these criteria, we can say that Changelly is slightly ahead of ShapeShift in its parameters. However, if the commission is extremely important for you, it is possible that ShapeShift will suit you more. It is also important to note that ShapeShift added a membership program in September 2018. As for Changelly, the exchanger continues to announce new partnership agreements with companies in the blockchain and crypto field. Further actions such as integration with various payment applications will help Changelly expand its user base and affect the future mass distribution of the platform.

Start Here for Much Wallet WOW!

EDIT 2017-02-10: A word about Nodes

There is a discussion about nodes that came up today, where it seems I'm discouraging people from running the full QT/Core client. Yes and No. What I'm trying to make sure people understand is how things work, and that it is NOT mandatory to run a client in order to use Dogecoins (and yes, I realise that browser-based tools like coinb.in and wallet sweepers are 'clients' by strict definition).
That said, more nodes is absolutely a good thing for the network. Preferrably full nodes. How do you run a full node? Just run Core/QT and open up Port 22556 on your router so it can connect to more than 8 peers. What will it cost you? You need your machine to be on 24/7/365, you need enough storage for the full blockchain (currently about 20Gb. Bitcoin is over 120Gb) and enough bandwidth to keep it in sync and share blocks with peers. A couple of Gb a month, most likely. This is best done with a desktop on a wired broadband link. Or maybe a hosted VM in the cloud. :)

EDIT 2017-01-09: Wallets WITHOUT Clients

Since I started helping people on /BitcoinBeginners, I'm getting a lot of questions about how to use wallets without running clients or trusting third parties. So here are a couple of resources that will make that possible, and not just for Dogecoin:
Multi-Coin Wallet Generator Now supporting 129 currencies! Coinb.in Start by setting the currency, found in the gear wheel in the Broadcast tab. Dogecoin Wallet Sweeper Redeem 'paper' wallets containing up to about 100 UTXOs. Bitinfo Charts My favourite block explorer, handles a bunch of cryptos.
Using these resources, it is possible to hold, receive and spend coins in various currencies, without having to run QT or a 'lite' client. You can also download and run the pages on your own device.

EDIT 2016-11-23: SEMANTICS about MINING! :P

Even though there is already a section on mining below, it has been suggested given the huge number of posts on the subject that this needs to be made clearer. Since people get their panties in a twist over the word 'dead', lets change that...

MINING IS DEAD!

MINING DOGECOIN IS UNPROFITABLE!

Put simply, there is no way to mine Dogecoin and make a profit because of the massive hashpower provided by industrial-scale Litecoin miners. Mining Doge directly stopped being viable when our hashrate exploded with the introduction of AuxPoW. Mining with CPU's and GPU's died when ASICs were introduced. And mining with a laptop WILL kill your laptop and cost you a fortune to repair or replace. Mining Litecoin with an exchange that also mines Doge and others will earn less than the electricity consumed, and you won't recover your costs. Probably ever, but certainly not in any reasonable time.
Mining other currencies may be a thing, but that's beyond our scope here. This is /Dogecoin, not /GetRichMiningCryptos after all. If you want to mine the newest scamcoin for fun and profit, look elsewhere for advice. :/
Oh, and most important:

READ BEFORE YOU POST!

At any given time, there are half a dozen posts on the frontpage just like the one you're about to write, where the answers have already been given. Read them. Don't make people waste their time repeating themselves because you were too lazy to bother reading stuff. :P
So there I was, having a quiet Sundy arvo bludge, as you do, when 42points turned up on Facebook and asked me to write a new sticky post for /dogecoin. Why would he do this, when he should be having a bludge himself, I hear you ask? Well, seems he was doing exactly that, and wanted to fob off the work he’s too slack to do himself. ;) Ah well, being a sucker for punishment, I’ll grudgingly oblige I guess.
OK, first things first.

EDITS:

From peoplma
I was wondering if you could add just a couple things. A link to the coinomi android wallet, it's probably the best one out there. And a sentence somewhere along the lines of "if you need help with any dogecoin software you are welcome to make a post, but PLEASE include your OS, version number of the client, and any relevant transaction IDs that you are willing to share" if you can fit that in somewhere.
Also, if you want to link to Prohashing, I'm pretty sure it's the only Scrypt mining pool that will actually pay out in doge. The others I know of pay out in litecoin or bitcoin. And it's a profit switching multipool, so gives a better return than just mining ltc/doge.
And there's these two wiki articles I thought would be helpful to link /dogecoin/wiki/technical for those technically minded newbies or intermediate users who want to dig a little deeper. And maybe a link to /dogecoin/wiki/dogecoincoreguide next to the link for dogecoin core.
From pts2002
Finally a proper sticky post! Here's some other stuff you could add:
zpool.ca mining pool - You can get paid in pretty much any coin, and you can mine in multiple algos (currently mining lyra2v2 with my GPU). Doing about 500Ð/day
shapeshift.io exchange - My favourite exchange, quick and easy. No registration required!
Also, you should add some blockchain explorers!
chain.so - Support for bitcoin, litecoin and doge.
dogechain.info - Official blockchain explorer. Includes a wallet (already mentioned). Live update currently not working (?)
EDIT: Here's another thing I found!
preev.com currency value calculator - Easy way to check the value of your dogecoins (or bitcoins, or litecoins, or peercoins)!

Changelly vs ShapeShift

Instant exchange is a popular way to trade cryptocurrencies quickly and efficiently. In our next few articles, we will try to compare and evaluate the most popular exchangers at the moment.
Today, Changelly and ShapeShift are still pretty popular services for these purposes. However, before using this or that exchanger, each cryptocurrency trader needs to weigh all the pros and cons.
In this comparative review, we compare Changelly ShapeShift and go through some of their key similarities and differences, according to the safety criteria, the commission, options for different cryptocurrencies and the user interface.
User interface
First, let's look at a couple of Changelly and ShapeShift in terms of user interface. This is the first impression that a trader who uses an exchanger gets.
Changelly interface is one of the most straightforward and easy-to-use interfaces among all cryptocurrency exchangers. For example, on Changelly you do not need to go to a new page to look at the trading options and calculate the exchange rate: all this information is at the top of the main page. Naturally, before you participate in the auction you will have to register. In addition, for their services, Changelly can sometimes take a significant commission.
Previously, ShapeShift exchanger was known as an exchanger without accounts. However, in September 2018, the developers decided to change the model of the platform to give users additional protection and reduce friction. Now, to trade on ShapeShift, you will have to register.
Compared to Changelly, for beginners, ShapeShift may seems more complicated exchanger. On its main page, a pop-up window "account required to participate in the auction" appears, which also describes all the advantages. After closing this window, you will find yourself on the statistics page, where you can see a variety of indicators. For example, you can look at recent transactions. Also on the homepage there is a 24-hour statistics of the number of transactions and BTC volume, the average order processing time and the most popular trading pairs.
Security
On its website Changelly stores no user funds. Instead, the exchanger sends funds directly to your wallet. It makes Changelly, not the custodian exchanger, which is usually safer than a conventional exchange, which holds users' funds. In addition, Changelly uses two-factor authentication (2FA).
In May 2017, one of Changelly's supporting accounts was hacked. Some users received the following message: "All customers who make an exchange from Bitcoin to another currency must manually transfer to the specified Bitcoin address:...". However, Changelly support immediately blocked this account.
ShapeShift, in turn, once used hot wallets on its website. It is unclear whether they can be used now, but users still remember the past vulnerability of the platform. In April 2016, ShapeShift exchanger was hacked and lost $200,000. Here's a comment from CEO Eric Voorhees himself: "the server Infrastructure was compromised and was under serious threat. We decided to quickly wipe out this infrastructure and build a completely new and secure environment." It is important to note that in the course of this, no customer has lost their money. The only funds lost belonged to the company itself. ShapeShift representatives called their own employee responsible for the incident.
Commissions
ShapeShift has quite a good commission for an instant exchanger. For each transaction, they take only a commission for mining. Some argue that this commission is somewhat overstated compared to the standard commission on mining, on which the platform earns. Anyway, for one transaction you will pay no more than 0.5 %.
ShapeShift does not return funds after failed transactions if the amount of lost assets is less than the mining commission. If you sent the cryptocurrency to the wrong address (for example, to GNT instead of ETH address), the platform will charge you a refund fee in the equivalent of 50 euros at the current rate.
As in ShapeShift, Changelly’s commission is approximately 0.5 %. However, many Changelly users notice that the exchanger has "hidden fees", but basically it isn’t, it is a result of high rate volatility of cryptocurrencies. For example, when you enter your existing funds (for example, USD), the amount transferred to another currency (for example, BTC) may differ from the current rate. And sometimes the resulting amount is the same as specified on the exchange. This should be taken into account when trading if you do not want to lose a small part of your funds. Although you should do this all the time in all exchangers.
The choice of currencies
Of course, the main advantage of both ShapeShift and Changelly is the variety of trading pairs. For example, you can easily exchange Qtum to Aragon directly instead of first changing Qtum to Bitcoin and then Bitcoin to Aragon, as is required on most other platforms.
If we talk about the most obvious differences between Changelly and ShapeShift, it is worth considering the availability of exchange to the ordinary money. In the exchanger ShapeShift there is not a single fiat currency. Instead, ShapeShift collaborates with Simplex to provide its users with this capability. However, even considering this partnership, your choice is limited to BTC-USD and BTC-EUR trading pairs.
About 33 cryptocurrencies are available on ShapeShift. There are several other cryptocurrencies marked as "temporarily unavailable", which may limit the use of the platform for some users. On the other hand, Changelly offers a large selection of trading crypto pairs (over 90) for USD and EUR. Also, this exchanger allows the use of debit and credit cards (Visa or Mastercard).
Geographic and transaction limits
ShapeShift and Changelly doesn’t have any restrictions at the place of stay. Users from all over the world are free to use both projects. This is good news, especially given the fact that now many exchanges can not boast of such accessibility.
If you are going to change large amounts, you need to take into account that each exchanger has its own limitations. ShapeShift has a relatively low transaction limit of $10,000 for level 1 users. By participating in the exchange, you can extend these limits. As of November 2018, higher levels (2-5) are not available to those who are not members of the community. The maximum limits of Changelly are from $ 50 to $ 10 000 for the first transaction, up to $ 20 000 per day and up to $ 50 000 per month.
Conclusion
So which exchanger, after all, is better? Having studied all these criteria, we can say that Changelly is slightly ahead of ShapeShift in its parameters. However, if the commission is extremely important for you, it is possible that ShapeShift will suit you more. It is also important to note that ShapeShift added a membership program in September 2018. As for Changelly, the exchanger continues to announce new partnership agreements with companies in the blockchain and crypto field. Further actions such as integration with various payment applications will help Changelly expand its user base and affect the future mass distribution of the platform.
