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.
We does not need to worry about the future of bitcoin instead we need to make our part or to deal with doing a particular thing for us to help bitcoin to developed. I think people or the support of the bitcoin user is the number one factor for bitcoin to experience development and change in terms of transactions, market, stock system and its value.
