This means that if a customer buys $3,000 worth of Bitcoin and withdraws it to a wallet they control, they would have to not only prove ownership of that wallet but also provide their name and physical address, along with additional identifying information.
Personally, my life stands to change very little. I’ve been living entirely off of cryptocurrency since 2015, unbanked since 2016, and have never used a centralized exchange, receiving all of my coins as compensation for goods and services. But as few live as I do, we will likely see a significant impact on how most cryptocurrency users conduct their business. I would hazard a guess that most users have interacted with a centralized platform requiring KYC.
For the rest of cryptocurrency users, the newly proposed regulations would put a significant friction point on deposits and withdrawals. At present, a user signs up to an exchange, submits KYC documents for approval, and can buy and withdraw Bitcoin to a wallet they control, including a hardware wallet for cold storage. When wishing to realize gains, they can then move the funds back onto the exchange and sell for spending money in the bank.
In the future, however, they may be required to prove ownership of the wallet to which they withdraw, including providing their physical address, and similarly, prove the origin of the funds when moving back on to an exchange. This may lead many users, including the privacy- and autonomy-conscious (of which there are many in the Bitcoin world), to seek other, less intrusive ways of using their digital funds. Making payments directly for the goods and services they desire, rather than first selling for fiat currency, avoids the headache of passing through the regulation-induced friction point every time.
