Imagine that economy that we know it today is not needed anymore, personal profit stimuli is just a page of a history and social and political life is just different from it's today version.
How then needs of people are solved, and on what would you spend your time and energy in that case? Did you see the crypto there, and if yes in what role?)
P.S. I know the Ideas of Karl Marks about post-komunism and not a fan of it)
The economy is improving because of that banks but since not everyone is wealthy enough to place money on banks then cryptocurrency is the answer for other people to become wealthy in the future.
The people who had invested in cryptocurrency will get profit.If you had keep your money in bank,it's no use.You will get 5-10% of interest from bank for the investments .But for that you have to keep it for certain period of time.For example,you have to hold the money for the period of one year.Cryto investments give more profit.
