A friend in Seoul can’t withdraw $700 without... proof as to why he needs more than $700. Like printed proof to bring to the bank in person.
He can however, move $500k/day on a local Korean crypto exchange.
Foreigners have sold Korean stocks every single day - mostly to domestic ultra-levered retail investors - since May 6, the longest stretch on record by far.
FYI, as this seems not widely known:
Most of the mega crypto funds have very permissive LPAs, which allow them to buy liquids in size, including BTC/ETH.
Keep that in mind.
