Worst cryptocurrency exchanges
So far I have found 3 exchanges that I would avoid at all costs.
Once used to trade some altcoins and then found out they got ridiculous withdrawal fees and barely any trade offers which basically forces you to keep smaller balances on exchange.
Customer support never replied to email so I went to Twitter where they blocked me right away after warning others about this problem.
On TrustPilot they are also removing reviews.
I had an account there for a while and when I came back to check my balance I found out they wiped off everything for being inactive.
Exchange that scammed PIONEER COIN for 29 Bitcoins and blocked on Twitter after that.
