Portfolio Margining for Crypto Products

i've always thought that i g out of the appeal of cryptos. I at least ave just assumed it was easy to get your money wherever you wanted. But as soon as i try to ever move money around, i realized how difficult it was. In crypto exchanges are fullstack products so everything is basically in a dark pool and no one knows what's going on. And everyone else has this like, very abstracted experience, going through two or three different companies for each trade.
