This is also what I am thinking of freelance crypto jobs and of course trading would always be the best choice but it does require some skills to maximize the profit from those two.
If you have funds then why don't you try some P2E games that are indemand right now or being hyped right now?
Try searching what game would get your attention but also try to do some research first before investing.
nft game is hype and attracting a lot of interest...
I'm also studying this, but it requires a lot of capital, for example, Axie Infinity, which requires a large amount of capital to buy characters but will definitely make a profit within 1 and a half months.
There are some NFT games that cheaper capital but assurance is the problem if those are legit like Axie infinity or just scammers.
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).
Blogger is making money these days and yeah this is one place to earn crypto in time.
