As I understand it, FTX outside the US offered many exotic financial products: e.g. 24/7 traded Tesla stock tokens[1], leverage, etc., which I don't believe US based crypto exchanges are allowed to offer(Coinbase stopped offering leverage in 2020, for example). The acquisition offer yesterday did not include FTX.us[2]

This may mean that the US part of the exchange and the associated customer funds were not lent out, but we shall find out.
