What cryptocurrency exchangers do you often use?
I have been use some centralized exchange most of them in the top 10. But I have some issue with rising transaction and withdrawal fees, thats why i used to find some fresh and innovative exchange i recommend XCH4NGE to buy Ethereum,Bitcoin,XRP,Bitcoin cash, Litecoin https://www.xch4nge.com/
Should be noted that this person is likely affiliated with said site, so take anything he says with a grain of salt.
I took the time to register on his exchange, and goddamn, it's a horrific mess. Best part, after signing up to this (what i think is a sketchy site) they dared to ask me for my ID/Passport.
Seriously, what are you thinking?
