Find something you can do to earn money online and choose programs that can pay you with bitcoin. This is a nice start cause u will not make much in the beginning and you can see it as hobby and save coins without cutting anything from your life before.
I always reccomend an own website/blog. It dont has to be crypto niche - you can do whatever you want (the most impotant thing is that u have fun with this niche, doing something that youre not interested in just cause it could bring a bit more, will mostly fail cause u can't hold the motivation).
Making money online is a good idea. If we are unable too save much money from our day job than we need alternatives. Getting a second income from online work is start to increase our crypto holdings. For me the best way to earn some extra cash is through ebay. Selling old stuff from the basement which I don't need anymore can make a decent profit which can all go into cryptos.
