Although of course it seems unlikely, all good things must come to an end and someday, in the distant future, the blockchain technology will fail. When it happens, what could replace it? Is there anything out there that functions similarly and just as good and reliable as blockchain? More importantly, if nothing replaces it, what will happen to cryptocurrencies then? Any ideas?
That's one of the things that I wonder about. It must be something better. But there is nothing that goes bad for Blockchain yet. Only the price of Bitcoin is falling.
