They are playing with these forks and no doubt that they are making big money on these coins, feeling sorry for the traders who are crying on the chat.
You feel sorry for the traders suffering from Yobit's scummy behavior? I honestly don't. There is so much going on with that exchange and a couple more in the same category, that you can't miss all the complaints.
People have no right to complain if they haven't performed any prior research. What's even more pathetic is that there are people knowing what's going on with Yobit, but they ignore everything and make use of it anyway.
In that case I actually doubt whether or not these people are mentally retarded. How can anyone knowingly put money in a scumhole that is likely going to result in nothing but problems? It's a pure form of insanity.
Research comes first, usage later, and not vice versa.
