I don't think one will consider it hard to get, except if u want to remain anonymous. If u are ready for verifications u can always get bitcoin except if u are from China
Yap, those exchanges that are requiring identifications can trust you now to buy bitcoins whenever you want. But if you are using a shitty exchange like yobit then you'll really have trouble for purchasing your bitcoins. And not only bitcoin is the one that's having problem there and also many coins. Not only with the deposits but mostly with the withdrawals.
Yobit have some issues for the coins out there and also for the withdrawals but the Yobit team are always working hard to solve the problems that they currently have in their exchange. I am trading in Yobit also and based on my experience, i don't encounter any problem with their exchange and in fact, Yobit is one of my favorite because it is fast to make profit there.
