The UK Just Sanctioned a Top-10 Crypto Exchange

The UK authorities have added the cryptocurrency exchange HTX to their sanctions list. That means anyone subject to UK law is now required to freeze any cryptocurrency received from addresses associated with the exchange. The sanctions have broader implications as well, but this is arguably the most troubling one.

HTX currently ranks among the world's largest exchanges - tenth among crypto exchanges for spot trading and eighth for derivatives trading on CoinMarketCap. Massive amounts of cryptocurrency flow through it every day. And now, from the perspective of the British sanctions regime - which many blockchain AML providers rely on - all of those flows risk being treated as tainted.

This is the first time a top-10 exchange has faced sanctions of this scale. It is still unclear how blockchain analytics and AML companies will react. Will they mark as "dirty" only the transactions made between HTX and its users after today's announcement? Or will they gradually begin flagging addresses that interacted with the exchange in the past as well?

Either way, this could push the amount of cryptocurrency considered "tainted" to absurd levels - unless companies like Chainalysis, Elliptic, TRM Labs, and Crystal Intelligence decide to quietly ignore today's decision. And honestly, I think that is entirely possible. Because otherwise the entire AML tagging system could end up collapsing under its own weight - along with the business models built around it.

Until the situation becomes clearer, I would strongly advise against depositing cryptocurrency to centralized exchanges. Simply because you cannot be sure that your coins did not at some point pass through HTX-related addresses - and that tomorrow they will not suddenly be flagged as violating UK sanctions, potentially leading to your exchange account being frozen.

The only reasonable exception may be assets without a traceable transaction history, such as:

• Bitcoin transferred over the Lightning Network,
• Litecoin held on MWEB addresses,
• XMR, ZEC, DASH, ARRR, and other privacy-focused coins.
