Look, just use your head. There is no such thing as free money, and so if it sounds incredibly promising and easy then it's most likely fake.
The first two look incredibly similar to each other, and the second one was
founded a month ago so definitely don't invest it that one.
The third one looks like they just took a one-page template and then had to fit an FAQ in there, so
went ahead and did it without knowing how to code anything further.
TL;DR: (is this post even that long) Don't invest in anything that gives you returns for free, so I wouldn't invest in any of those.
