The fact that now bitcoin has fallen in price does not mean that this is the end of the era. As with all great things, there is a great demand at first, then demand falls, then again increases, but the great remains great. just soon interest will settle and bitcoin will remain on the peaceful side, where it will be used by everyone and everywhere. I do not believe that other cryptocurrencies will ever beat Bitcoin and Ether. But this does not mean that there are no bad altcoins.
