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 can't see any reason to be worried about bitcoin. Just consider bitcoin as an opportunity to earn. Join bounties and have an invest from the bounties that is being paid to you. If price of bitcoin is falling down, it will rise up soon. Nothing to worry. Enjoy even if its a dip, grab it as an opportunity to buy.
