Brazil's central bank just made moving money to your own wallet a flagged event. New rule: exchanges have to wait 24 hours after you fund your account before you can send more than $10k to a self-custody wallet or a foreign exchange. Flagged smaller transfers get held until a "documented review". Kicks in Jan 1, 2027, stablecoins included.

Honest part first: the scam flows are real. Fraudsters push victims into "self-custody" wallets the fraudster controls, and a cooldown gives providers time to catch it. I get why they call it consumer protection.

But watch the frame. They don't ban self-custody, that'd be too honest. They just make it slow, suspicious, subject to somebody's review. A state that needs 24 hours to decide if you can touch your own keys has already picked the default custodian, and it isn't you.

We're supposed to treat self-custody as the norm and exchanges as the risk. This rule flips that. The flagged, delayed, reviewed action is the one where you hold your own keys. That's the tell.

my keys, my call. 24 hours is the state asking for a head start
