I would assume you would like to find ways to earn money that are of course related to cryptocurrencies otherwise you wouldn't post your inquiry in a bitcoin discussion forum. I would highly suggest you learn how to day-trade as it offers you the quickest profits in terms of trading. If you're open to reaping the benefits after a while, then you can study the market itself and determine which assets would be best to hodl on your wallet for a while. Otherwise try to learn a skill or work on a talent that you already have, and capitalize on it. I personally have a knack for writing stuff so for a while I worked as a freelance writer. I'm not saying you should try to write too, but giving you a bit of an idea on what you can do.
Before we talk about freelancing, someone must have a set of skills that they can offer to their client(s). But if you are not well fitted for the job then don't do it you might as well embarrassed yourself if you have no courage to finish the job. Someone must have at least an experience of what they are going to do so they will do their job right.
And as of OP that has a vast experience about computer, he might as well freelance it if he doesn't have any stable job yet. Better harness those skills that we are good at so it better pays off someday.
I mean if you're looking forward to working freelance, it's given that you should have a competitive amount of skill on a particular field otherwise you wouldn't have a chance on getting hired. Vast experience would also most of the time equate into substantial amount of skill for the client, so even if you think you're still not good at let's say writing, long as you have been writing stuff for a long amount of time, like 2-3 years per se, you should be good to go.
