I dont think so, but the only one who can destroy bitcoin is bitcoin itself in which if this isnt functioning well, or the amount depreciate in its lowest peak , failed transactions, scam signature campaigns it will definitely be gone, who will gonna be interested in investing here? I think so.Some speculation may come that bitcoin will be gone if there is possible other crypto-currency who will sprout in the next few years and run Above bitcoin and where in users could be more profitable.
