Well, if you already have quite a good amount of earnings from cryptocurrency, then why not? You could start even just a small business. It's more of an investment actually, and it's much better to have more investments. But of course, be sure to put it in a business that you think will give a good return. It's really nice to have a passive income. Personally, I think a lot of people will really get tired of being an employee, given that there are a lot of ways to earn money online, in a much easier way.
