I dont think there is cominga big drop again becuase the bitcoin will last for ever some body sayd to me and i need to believe him and when tyhe price is going to drop that much i am going to sell any coin i have for sure!
There's no comming big drop in bitcoin because bitcoin is getting stronger nowadays and if somebody drop the bitcoin price it just because of some wallet will going to be hacked. And i believe that bitcoin will be more expensive after the year 2016 and it will be more reliability to sell and to resell or buy bitcoins.
No there will not occur a big drop in the future maybe a small drop but that will be all, the bitcoin has a good future and it will not go down anymore than around the 600 dollar in my eyes.
I really hope the bitcoin will prove itself because it has a good future.
