Although we may be unemployed one day, we must have a plan in advance for everything. But it is not recommended to take investment as your main job, whether it is investing in cryptocurrencies or other investment projects. Investing requires sufficient experience. Don't think you are a professional investor just because you have made several successful investments. Investing is a long story. You can do it as a side job.
Apart from knowledge and experience, investing requires money. How can you get money for investing if you are unemployed? I mean, borrowing money for making investments is the worst thing you can do, economically-wise. From being just without money, basically a free man, you are risking to become indebted, or, in other words, to become a slave of your debt. Don't do that.
