I tried to trade a couple of times at Etherdelta. The first one trade gave me some profit but the second one resulted to loss of some shitcoin named as iBTC OLD. I unlocked my MEW, deposited iBTC OLD to the burse and makea bid. Then I exited and some days later after entering to the exchange again I saw that there were 0 iBTC OLD in my MEW wallet, but all the rest of crypto were in it.
There were 3312 iBTC OLD and it costed only 20-30 bucks at that moment So it wasn't a very big loss 'cause I got'em for Airdrop.
