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.
Axie already jumped high and if you are going to start you needed to invest decent amount of money, but like what you said I also heard that from doing the quest you are capable to see your investment withing a couple of months.
Good enough if there's no problem that happened to the server and the game continue to run smoothly.
