i'm not sure bitcoin wll get some good achievment this year,bitcoin goes mainstream several years ago,and more popular until this year,even bitcoin price still unpredict and really fluctuate,but bitcoin not lost it hollder and adopter,bitcoin still have so many "fans" .
lets hope on future bitcoin will compete paypal more and more,and take over 2% population who hold by paypal.
But all this don't mean that price must rise astronomically. If Bitcoin succeed to takeover Paypal business ,which i can imagine is possible, it still can fall to 100$ or less because it is value not service, and can be manipulated.
Someone will say this is death or end but, no this is free trade. Everything is possible.
