I would not want to exchange as coinbase.
coinbase can block your money that has already been before.
and not everyone can afford the required documents for trading on these exchanges for various reasons - ID card or international passport, various bank statements at the place of residence, etc.
so the community will lose not a few of his admirers DMD.
DMD, BTC and the currency of the country in which the person lives a better option for most, is my opinion.
I can understand difficulty with documentation ... how do you BTC -> Currency
Coinbase is only one I know here in USA that is fast and deposits direct to my bank account. It WAS a pain to get set up but works when I need it (DMD price too high, I just sell BTC for cash LOL).
BTC still on the rise
I will also second "Coinbase" as a great exchanger of USD -> BTC and vice-versa. I have used them for a few years now with NO issues at all. They do use KYC rules so as long as you have nothing to hide you are golden!
