The easiest legal method I’ve seen to earn crypto is Coinbase’s education program where they reward you with alts for watching little videos about them. Besides getting paid to watch many videos about alts, you can also share your referral link and earn $ each time someone else earns free crypto.
Here is my referral link (for demonstration purposes) and anyone who clicks it, signs up, and watches the video will get an extra $10 as well as me getting $10. Maybe not the get rich idea you’re looking for, but anyone can do it, it’s free, low risk, and you don’t have to pay me for the idea. You could just earn crypto with me.
