You say that because you haven't heard of the latest crypto investment form. You put $140 at least 6 month in a new cryptocurrency deposit. In exchange, you get paid every tuesday during this time, you also get sent a red visa card and a premium Spotify account (you never have to pirate again!). Plus, if you're referred, you and your referrer will get $25 dollars free.
Now, when I asked where did that money come from, the guy on Twitch told me "it's like a bank, the money comes from you". The difference here is, of course, this gives you much, much higher returns than a bank while a bank can actually invest your money, and this "entity" cannot. Also the interface of some of these "investment" agencies look like a game, I guess to be more attractive [1].
In the end, the idea is always the same: crypto will only go up. So far that's been the case, though.
