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.
