My mistake ((I really did not properly signed the first ticket confusing name ((This is just for Europecoin. But the appeal on its designation - ERC I wrote right ... I bought the ERC on bleutrade to sell on bittrex. Then there was not any warning that the coin called ERC is different on these two markets. Now continue this coin with different protocols (v2 i v3) as stated in the same coinmarketcap - http://coinmarketcap.com/currencies/europecoin/#markets
