A question for anyone who says that cryptocurrencies are fading away and we will disappear

I say

Will the people who rely on trading their money in the stock market and through platforms stop trading and take their profits to open a shop or supermarket or buy real estate or a car

Has anyone withdrawn the money they earned from their electronic wallets and bank deposits or from the stock market

Of course the answer is no

So this pattern of work will continue because it is the only work that receives millions of citizens, and without it, three-quarters of the Earth's population would lose their jobs

Is this correct

With the presence of machines and robots and many factories dispensing with human labor

What do humans do? Where will they get their income?
