bitcoin price, if you look at the charts, goes down about 90% of the time. the rest of the time it rallies up. that's the nature of iterative price discovery process.
It will bounce back?
yes, of course it will. it bounced back after crashing to 1/16th of it's max. then to 1/6th. now it's just 1/4th (if it drops to $300 which it even did not yet), absolutely no reason to panic unless you need to cash out right now.
