The US just cut MEXC off from its financial system — and if you trade there, this one matters more than another price dip.

FinCEN ordered MEXC Global cut off from the US financial system under the Combating Russian Money Laundering Act, with the Treasury saying the exchange facilitated at least $16 billion in illicit flows. That's not a hack or a rumour, that's the US government formally naming an exchange a laundering channel. (CoinEdition's recap of today's Treasury action.)

Here's how I read it. MEXC isn't shutting down tomorrow — the order targets US financial institutions dealing with it, not your account directly. But this is the same playbook that ended other exchanges: first the banking cutoff, then payment processors and stablecoin issuers start distancing themselves, then withdrawals get slower and messier. An exchange that loses its fiat rails becomes a much harder place to get your money out of.

My honest take: if you keep funds on MEXC, treat this as your warning shot, not your exit signal. Move what you don't actively trade into self-custody or a venue that isn't under active US enforcement. And expect the scammers to move fast — every big exchange headline this month has spawned fake "withdrawal help" and "priority processing" DMs, and this one will too. No one from MEXC will ever DM you to help you withdraw.

The bigger picture is uncomfortable: in one week we've had a $6.3B exchange hack and now a major exchange cut off for laundering. The trust problem in crypto isn't just hackers anymore — it's the venues themselves.

Do you still trust your funds on an exchange under active enforcement action, or is this the push to self-custody?
