Ok I have pretty much tested every exchange. Been using binance, bybit etc on mobile been excellent. I thought to finally give ftx try. Installed ftx pro but damn one of the ugliest app in crypto space. The interference is terrible and looks like just website created as app( which might be true i think). I was just shocked to see one of the most famous exchange with such terrible app. And the i decided to trade did level 1 verification thought it would be enough as they didn't tell about any limitations on trading except amount withdrawal limit. And then was unable to do trading because now it tells me i need next level verification for derivatives trading. And i also realised it doesn't have option to use usdt for trading( not sure about it)

From every angle it looks so terrible but there maybe more to the story why it is still so famous. Can anyone elaborate it?
