Thats true, if everybody knows crypto specially those who dont have stable job it will help and also it can be an extra income to others. But of of course knowledge about crypto is needed . You need to learn for you to earn a good profit.
But the market is not looking good at the moment. The probability of losing money is greater than earning some profit so it would be better to get a regular job and not rely on crypto. Learn about crypto but don't make this a regular job.
