Participating in social bounties for new ICOs has been good for some people. You can read about a lot of those in here and what you need to do to get a reward for promoting their project.
If you have a smartphone you can get some apps that pay out in tokens for certain activities. I use Storm Play and have earned about 1250 Storm tokens in the last 2 months just from playing games and stuff.
And if you have a PC with a graphics card, you might be able to mine some coins for the cost of electricity for your card.
That's all stuff I've been doing lately...haven't really put any money toward crypto, just time and electricity cost for mining. Lots of YouTube resources for that stuff if you want to learn more, or browse around on the forums here.

but be aware that this is 75% scams and the remaining 25% has no accuracy about payments
And if you have computer skills then offer here or find in service whos looking for your ability for them to pay
