If you can grow your network then try asking around for testing positions for some crypto games. A friend of my acquaintance told me they get a couple hundred from being a tester, basically a QA job for some alpha/beta crypto games. Requires you to have a network to even join in in said testing though in comparison to live and released games. 

As for anything steady and worth it, I hardly doubt there's any like that left. There are some bonuses and promos that are still up and about related to Axie Infinity but they aren't necessarily a guaranteed return to you, more like lotteries really.
