<…> The guidelines will require companies ranging from exchanges Coinbase Inc. and Kraken to asset manager Fidelity Investments to collect information about customers initiating transactions of over $1,000 or 1,000 euros, as well as details about the recipients of the funds, and to send that data to the recipient’s service provider along with each transaction.<…>
What is technically non-feasible as is, is the part I marked in bold in the quoted text. If one sends BTC from an exchange to his Ledger (or other) wallet, there is no way to associate the recipient’s information other than the wallet address itself. To comply, one would need to either change the protocol to "add" information of the recipient (not going to happen I assume, since it would require associating identities to all addresses), or the exchange would need to perform a KYC (them or someone third-party entity) on the recipient himself, thus implementing a protocol for KYC customers only for both ends of a TX. That, in principal, would seem like something that would just push people in search for more anonymous alternatives, let alone the fact that it seems pretty wild to impose and implement.
I don't understand why you think is not feasible.
They will simply keep a record for the transactions from which addresses they sent the fund to the exchange and to where they withdraw.
It's already been done by a lot of exchanges which do keep track of the addresses they customer use.
Mt gox, for example, was doing this for some of its clients.
Besides, there is a huge open public database with all those transactions, the blockchains themselves.
When you deposit from address A the address gets linked to your account. When you withdraw to address B, it gets linked to your account and identity. When somebody else deposits from address A to another account probably it will trigger some flags.
You can sue. Once they start passing laws. People can sue the SEC and CFTC and force it to the supreme court and pressure congress into reevaulating the g20 meetings.
Nope, you can't.
You can't sue the government for enacting laws, you can't sue the government for not enacting laws.
Let's all sue the governments for raising taxes
Besides, you're mistaken what the FATF and what the CFTC is doing and what regulations are they involved with.
Second, the g20 meeting is simply a meeting, the G20 has no power over internal politics.
