As much as I'd like to agree with you that Bitcoin would be the one you're looking for, I'd highly stand against it simply based on an objective perspective. Even if we're looking at it for a long term perspective, it still stands that Bitcoin is an extremely volatile asset. What you need right now is a stable asset that could simply provide you with a higher chance of success of getting profits, and Bitcoin is not that. What you're doing is similar to how a gambler goes in on a game to win it big imo. If you have extra funds, ones that you can basically afford to ignore as part of your life, feel free to do so, but if you're in need and want to spend every penny for all it's worth, then avoid Bitcoin.

Not sure if it could help since you're in a third world country, but try looking for beer money services available in your country. I use some of them myself (testable minds) which give me a few dollars every now and then if I'm lucky with the timing. Don't expect to get huge amounts from it though. There's also freelancing services out there, local ones in third world countries have low pays even with difficult jobs, so that may be quite difficult in it's own way.
