The bitcoin is the currency of the future. It will help mankind grow to another level. It is like the invention of the first computer. Cryptos are the beginning of a new era and must be used as global currencies. I mean all countries must use the bitcoin instead of their currencies. It is not stable like gold but it is solid. How many times people predicted the end of bitcoin? How many times has it come back from ashes. One money for 1 world. We just need time to make it come true.
Bitcoin's main vision is to become a world currency, but I think it has failed.
the reason is because of the limited amount, there are only 21,000,000 bitcoin in the world.
and it can't be for the whole world, it won't be enough.
