If your health is healed, your mind will remain clear so you can think well. Many people today are using the internet to earn income, one of which is in this forum, and you can also follow bounties, airdrops, testnets and so on. The important thing is to keep learning and learning because by learning you will get a lot of knowledge, skills and insights so that you can use this crypto technology to make money.
From the submission of the earlier reply, it suggests the perspective from which some people view crypto. Crypto is most at times viewed as a get-rich-quick platform where you can invest or trade a little amount of cash with the expectations of cashing out big as a return on their investments but things don't work in such ways. One doesn't only need to invest in cash, but also in intellects, reasons why I agree with @ndutbdut on his submission for the sick to be healed first before going back to bitcoin.
