In most well developed countries there are local services allowing you to buy and sell Bitcoin without going all naked, and if you buy your coins there, send them over to an exchange as Binance to trade. As long as you aren't touching fiat, in most cases an exchange as Binance won't annoy you with verification requests. Bittrex is too trigger happy when it comes to freezing accounts. They ruined my legacy account. Not my cup of tea.
