The thought does not have an argument or thought that does not have a basis of origin, only the chatter of high-ranking, you must not lose your memory, Trump is only 5 (five) years, after that all talk does not mean anymore, it is a fact, Trump is not the first president in the US, remember that.

The world economy has existed and developed before Crypto was present in the general public environment, 16 years was not something that must be confirmed forever Gold, copper, silver, bronze and so on far have existed before, the 20th century AD people's lives were measured with precious metals and it continues to develop until now.

I asked the OP for what year the internet was found and developed and what year Crypto was developed, we could not measure the economy of a value that was not in the form and What percentage of people in the world understands Crypto, so the crypto currency is created not to eliminate everything that humans have, remember that.
