One thing is sure, BTC will find a bottom, everything else is just speculation. If that is Titanic type of bottom remains to be seen.
I was mining with a profit when bitcoin was at $250 (Because of the us gov. Silk_road auction dump). Today btc is at around @7000 and alot more traders and exchanges than before.. Mt. gox dump??
When bitmain can't sell any more devices for mining the price will rise.
