best site to earn money online.....

Are they "legit"? If so, I am interested in joining it, but as I saw lately there are many scams. By the way I joined a site 2 or 3 years ago and I remember I made like 100$ in just 3 days, but what do you think it happened? It ended saying the site has problems and it had to shut down their activity... Anyway if you say this one is OK, let me know and I will join.
