https://cointelegraph.com/news/this-researcher-says-bitcoins-elliptic-curve-could-have-a-secret-backdoor

Does the author (MICHAEL KAPILKOV) not understand the details of his own article, is it just another poorly written article, is it clickbait, all of the above or what am I missing???
secp256k1 is used for private keys, not secp256r1.
The article says at one part, "One of the world’s top cryptographers believes that Satoshi Nakamoto chose Bitcoin’s (BTC) elliptic curve either for its efficiency or because it may offer a secret backdoor." Yet further on, the article quotes the same top cryptographer to say, "In contrast, the Koblitz curve parameters are mathematically determined, and there is little possibility for setting such a backdoor.”"
Finally, Cointelegraph quotes Wladimir van der Laan to say, "Even if Secp256r1 has a vulnerability, no one has stepped forward yet to announce their discovery. On the other hand, keeping this discovery to themselves could yield a multi-billion dollar reward." secp256r1 vulnerability leads to a multi-billion dollar reward? Where is secp256r1 in bitcoin?
There is much room for improvement in this article if I am not missing anything.

ECDSA: How does Bitcoin "chooses" the Elliptic Curve point?

Recently I've read about point addition in elliptic curves and the ECDSA and became curious about how it is applied in the bitcoin code.
I've learned that the main idea is, given a point P in the elliptic curve, the relation is:

X = xP, where x is the 256-bit integer number Private Key and X is the Public Key.

So, my questions are:

1 - How is the point P "chosen"? Is it the same everytime? Or is it randomized?
2 - How is X format defined? Do you just concatenate the x and y coordinates of P?

Bitcoin transactions linked to illicit activities – such as dark marketplaces, ransomware wallets, or fraudsters – have remained below 1% of the total amount for the past few years, according to new data from Elliptic.

The blockchain analysis firm said that the percentage of illicit bitcoin transactions has declined from about 35% in 2012 to just less than 1% as of today.

A list of upcoming "Bitcoin fork" being promoted for "dividends"

The following comment was removed in /btcfork - not by any moderator afaics so I guess it was automated spam filtering.
But it is an excellent example of how Bitcoin forks are being promoted to further the "dividends" agenda of diluting the importance of hard forks as methods for upgrading Bitcoin, and making them seem to serve no other purpose except money grabs or scams.
This was posted by user "solracor" in a post titled "Próximas Bitcoin Forks 2017 - 2018 - Dados CryptoCurrency".
It is recommended to be very cautious when dealing with these forks, no doubt some of them are outright scams which will try to get people to enter private details and keys on websites to steal their coins.
I am posting this here only for awareness of possible scams.
Get ready for a wave of Bitcoin forks! Bitcoin forks: 12 until early January! Upcoming Bitcoin Forks 2017 - 2018
Without further details, the following Bitcoin forks are planned for 2017 -2018 (we'll add more forks as they are announced and notes how forks occur):
  1. Bitcoin Diamond (BCD) is a fork of Bitcoin that occurs at the predetermined height of block 495866 and therewith a new chain will be generated as the BCD. Bitcoin Diamond miners will begin creating blocks with a new proof-of-work algorithm, and will consecutively develop and enhance the protection for account transfer and privacy based on original features of BTC. This will cause a bifurcation of the Bitcoin blockchain. The original Bitcoin blockchain will continue on unaltered, but a new branch of the blockchain will split off from the original chain. It shares the same transaction history with Bitcoin until it starts branching and coming into a unique block from which it diverges. As a result of this process, a new cryptocurrency was created which we call “Bitcoin Diamond”.
  2. BitcoinX (BCX): an intelligent contract (like Ethereum) based Bitcoin. Block 498888. https://bcx.org/. NOTE: Snapshot has already occurred; Futures are being traded, no currency has been released.
  3. Super Bitcoin (SBTC): like BitcoinX, an intelligent contract based on Bitcoin. Block 498888. http://www.supersmartbitcoin.com/index.html. NOTE: Snapshot has already occurred; Futures are being traded, no currency has been released.
  4. Bitcoin Platinum (BTP): According to the website, "Satoshi's original vision of decentralized electronic money". Around 12 December. Blocks 497757 / 498533. https://bitcoinplatinum.github.io/ko.html TIP: Bitcoin Platinum is rumored to be fake see: Bitcoin Platinum Created by South Korean Teen as a scam, the local market is erupting.
  5. Lightning Bitcoin (LBTC): A fork that is intended to provide "fast lighting fixtures". It uses smart contracts and can host decentralized applications like Ethereum (and Super Bitcoin). On December 23rd. Block 499,999. http://lightningbitcoin.io/
  6. Bitcoin Cash Plus (BCP): according to the website, "fulfilling the original promise of Bitcoin". Around January 2, 2018. Block 501407. http://www.bitcoincashplus.org/
  7. Bitcoin Silver (BTCS): According to a BitcoinTalk forum, the currency aims to "Make Bitcoin Decentralized again". Apparently, it occurs "in December." The site was up, but now it's down. This is not a good omen. https://bitcoinsilver.io/ - then see bitcointalk.org instead - https://bitcointalk.org/index.php?topic=2311582.0.
  8. Bitcoin Uranium (BUM): According to a BitcoinTalk forum, the currency aims to "Make Bitcoin Great Again." Apparently, it occurs "in December." Https://bitcointalk.org/index.php?topic=2316506
  9. God of Bitcoin: Without preminar, it is apparently a Christmas gift from Chinese investor Chandler Guo. Occurs on December 25th. Https://cointelegraph.com/news/forgive-me-father-for-i-have-forked-investor-to-release-bitcoin-god.
  10. Bitcoin Atom (BCA): Bitcoin Atom is a bitcoin fork with segwit enabled with atomic swaps, hybrid consensus and ray network. Exact fork block / date TBA. See: https://bitcoinatom.io/.
  11. UNITEDBITCOIN: LINKING VALUES AND SERVING THE WORLD! The distribution of phase 2 of the UBTC will occur at the time of block # 501878. UNITEDBITCOIN UPGRADES BITCOIN THROUGH THE IMPLEMENTATION OF INTELLIGENT CONTRACTS. Bitcoin Labor Testing and Emission Model, with new high speed smart contracts. Future Lightning Network support for faster, more cost-effective transactions. UnitedBitcoin (UBTC) will be allocated to active Bitcoin portfolios at a rate of 1 BTC to 1 UBTC at fork time. Without pre-mining, stable system with fixed reserves in fiduciary currency See: https://www.ub.com/
  12. Bitcoin Interest ("BCI") is a frictionless global payment system that focuses on three main areas of Technology, Community and Savings. Our payment system has a new integrated savings technology that allows our users to park their coins and earn interest. January 22, 2018 at 11:59 PM GMT, or in block 505083. See: https://www.bitcoininterest.io/
To summarize the above and connect some points, Super Bitcoin and BitcoinX are Ethereum competitors (as they use smart contracts like the Ethereum network), Bitcoin Platinum and Bitcoin Cash Plus are basically competitors of Bitcoin Cash (Bitcoin's competitors as currency ), Lightening Bitcoin is a blend of Super Bitcoin / BitcoinX and Bitcoin Platinum / Bitcoin Cash Plus (since both are designed to be competitive as currency and uses smart contracts), and Bitcoin Silver and Bitcoin Uranium are competitors of Bitcoin Gold ( competing for Bitcoin as a valuable store that is profitable for mine), and finally Bitcoin God is a Chandler Guo Christmas gift (simply meant to reward people for having Bitcoin).
This may sound crazy, but if you think about these as user-triggered dividends, it starts to make a little more sense.
To ensure you get your coins from the Bitcoin forks up to the Bitcoin, you are holding: Make sure to be in a Bitcoin wallet that supports the forks (Coinomi multiwallet with over 300 different coins has been good on this), an exchange like Binance with a good record of support forks (Binance supported Bitcoin Cash, Gold, Segwit2x, Diamond and Super Bitcoin and offered futures on the snapshot date or around the date of each snapshot, meanwhile as a user pointed out, hitbtc has been good at supporting forks, Super Bitcoin futures have been traded on hitbtc immediately after the fork, for example), or otherwise being in control of their private keys when forks occur (for example, in a portfolio like Bizcoin Core)!
Unknown. Here are some of the other Bitcoin HF / air drops planned for 2018:
Bitcoin Rubies (BTCRUBBY) https://www.bitcoinruby.io/ ERC20?
Bitcoin Dollars?
Bitcoin Stones?
Bitcoin Script BTCS reborn from the ashes?
Bitcoin Steel?
Bitcoin Razor?
Bitcoin Bronze (BTCB). Symbol: BTCB Decimal: 18 Total supply: 50 million ERC20 Distribution Airdrop rounds Round 1 Airdrop https://bitcoinbronze.io/
Bitcoin Iron?
Bitcoin Atomic (ATOM) Atomic Coin New Blockchain is coming out soon. Let's launch a new chain of Atomic Coin blocks with faster features. Then, deposit your atomic currency for exchange in the Web wallet before 1/1/2018. https://www.atomicproject.org/
Bitcoin Elliptic?
Bitcoin Hash?
Bitcoin XOR?

The Bitcoin Big Bang by Elliptic.co Bitcoin 101 - Elliptic Curve Cryptography - Part 4 - Generating the Public Key (in Python)

Elliptic is the global leader in detecting and investigating Bitcoin & Ethereum cybercrime, providing forensics, AML software and more to risk and compliance teams, investigators and law enforcement agents. Elliptic Curve Digital Signature Algorithm or ECDSA is a cryptographic algorithm used by Bitcoin to ensure that funds can only be spent by their rightful owners.. A few concepts related to ECDSA: private key: A secret number, known only to the person that generated it.A private key is essentially a randomly generated number. Elliptic's proprietary database delivers auditable proof of identity for millions of addresses in multiple cryptocurrencies including Bitcoin, Ethereum, Bitcoin Cash, Litecoin & others across thousands of real world entities.. Gain the confidence you need to investigate, evaluate and pursue suspicious activity in cryptocurrencies. The Elliptic Data Set maps Bitcoin transactions to real entities belonging to licit categories (exchanges, wallet providers, miners, licit services, etc.) versus illicit ones (scams, malware, terrorist organizations, ransomware, Ponzi schemes, etc.). The task on the dataset is to classify the illicit and licit nodes in the graph. We help Bitcoin and cryptocurrency exchanges expose risky transactions. Our software monitors billions of dollars in transactions every month, so you can enhance your risk scoring and simplify AML compliance.
