How and why would the end of bitcoin (and any other cryptocurrency) occur? Value decrease? Legality issues? Different technology/ideas to supersede it?
I guess, bitcoin would end if there would be another coin or another famous campany that can overpass or surpass the bitcoin itself. Although it has a very low chance of happening, the highest chance would be the law or the government banning bitcoin to their country. But the worst thing that could happen is that the bitcoin would be hacked completely and its value will be useless.
