Nothing to fear or worry about the future of bitcoin. All that's happening with bitcoin is positive and till date haven't shown any signs of destruction. If it is towards the end, now the entire technology advancement should have come to an end without new usage implementation.
I am worried about bitcoin future also. I am just starting my earnings and there is a lot of opportunity with it. Even though there are a lot of news that circulating about bitcoin i am still positive about it and i am not getting off myself in bitcoin. I still believe that bitcoin will surge after the occurrence of some issues.
