Quite simply, the well-known businessman John McAfee, Robert Kiyosaki, author of a collection of famous books all over the world, and many others, expect that the dollar will disappear in the future the crypto currencies like bitcoin will take its place.
crypto currencies are the currency of the peoples and not supported by governments. they are the refuge of countries looking for the future, which seek refuge to avoid economic sanctions such as Venezuela and to avoid economic crises such as Zimbabwe or to change the balance of power in the world like Russia,
Maybe we will see booms and falls within the next ten years, but in the long run all the future is the technology of the blockchain.
Here everything is correctly said, - All to the last letter. Time will tell, but judging by the fact that there are already countries that, at the legislative level, introduce Bitcoin into circulation, it means that other countries will adhere to digital currencies in one way or another.
