I don't see any reason why bitcoin will drop into bottom instantly i know bitcoin will be drop slowly but not into that price i know bitcoin will be more expensive and it will never be at that price, Our Indian mates are start adopting or imposing bitcoin to their community and bitcoin will be geting more stronger.
Yes I also doubt that bitcoin will ever cost 100$ again. Even some big hacking attak can't drop bitcoin so low. It's never late to buy bitcoin if you expect the price rising, cause bitcoin will grow higher, especially after next halving in next four years.
