The crypto transfer fee is ridiculously high (.1 bnb vs .001 bnb from Binance.US, for example). But, for me, it ended up being less than the debit cards fee charged by simplex (in trust wallet) on the initial purchase (no fee on cards the first 30 days at crypto). And you can transfer from crypto to trust immediately. New funds added to binance have a 20 day hold before you can transfer them off the platform.
