There's a hard fork around the corner and this will surely impact pricing. Bitcoin can also be easily stolen...the whole of it from any exchange. Mine was stolen off Bittrex yet I had the two factor authentication enabled.
A friend had a malware sent on his PC that infected the Copy and paste buttons and he was sending Bitcoins to the wrong address.
What am simply saying is that....its too risky to borrow money for such an investment...its better if its from your own pocket and you can withstand the shocks since this is new technology and it comes with its own problems

All that said...the ball is still in your court...its your money !
