WTF Mintpal. I sold at 18 and wanted to buy back in at 17. I have been doing this all week and have made a considerable amount, however, when I saw it rising I went to cancel to buy back in, I don't mind loosing a little as I am still up overall. I tried to cancel and I can't. Now it's at fucking 30! So i'm pissed off right now. I've basically lost half my coins, and if it keep on going then forget it, ill just put my BTC into another coin. Fuck this.
