Is Bitcoin the future of currencies? Well it's too early to say right now, but probably not.
Is Bitcoin the future of crypto currency? It is for now and will probably continue to be so for the next year or two.
When it comes to understanding which crypto will last, we can't really peer into the future and get told which coin is worth it. A altcoin could end up on top of Bitcoin a few years from now, we simply don't know.
Always thinking the same it, it is too early to say that bitcoin could become to be a main currency of all or a global currency and let's say if the bitcoin cash of other crypto's would simply move on top of bitcoin or when will bitcoin would last, or what could happen if all the coins are already mine then what is next for bitcoin in exceeding more with it's price, but a common thing that can happen is that the price would surely skyrocket to the moon but what is the last prediction with the price of bitcoin.
