If these governments want to make their people rich, they could increase their wages to upto 10 times, around $100/per hour. When wages will be high, more amount of money could be invested in Crypto.
Did you just completely ignored your high school economics and think this would make all their citizens rich? If they increased the minimum wage up to a higher level nothing would change since the people are getting a lot of money the the price of basic goods will increase as the supply of money got higher. What your proposal is basically like a careless government's solution on printing out more money to solve poverty and they completely ignored the fact that inflation is inevitable. Giving higher wages isn't the solution here to solve poverty just by providing jobs, proper education, and proper development of the country is enough for all of the people to go above of the poverty line.
