Actually, crypto is a chance for poor people to earn money. Even if you don't have capital to invest, you can invest your time and play NFT games or participate in different airdrops, bounties, ambassador programs. It all requires time but if you need money and don't have opportunity to work in other places, it will be the best choice for you. I have heard a lot of news about people from Africa who earned a lot thanks to Axie.
I would not call your methods reliable to raise your financial condition.
In the absence of work, sitting on the net for participation in bounty programs or games is, in my opinion, a waste of time, nothing more. But of course, different countries have different needs, and I also see a lot of people here participating in bounty programs who hope to earn something. But as practice shows, almost all works are often in vain.
A better way out would be a deep immersion in the study of bitcoin, and the further acquisition of a profession that will always be relevant on the Internet.
