I'm quit trading too.... I depost 1 btc when it's 700$.. I make huge profit to 22 btc when it's 3000 and I lost 12 btc and sold 10btc when it 2k8$... now it 4k4... I'm feel very bad, very sad
Did you use futures to go from 1btc to 22btc? I had a friend who used a popular chinese futures exchange and went from 0.1 to 4 btc in a week, then lost it all.
