Do you have some ground and analysis on which you base your prediction about price dump or this si just the pure guessing? Because you also suggest to sell. It' s hard to predict the Bitcoin market but at current point of view it doesn't seem that new dump is on the horizont.
After what happened on August 1, I do not presume to predict the market of crypto-currencies. To date, it even seems that Bitcoin is in danger, because of its split, because a double is possible as a Trojan horse. Maybe I do not understand this much, but it worries me.
