Hello guys.
I met the website bitcoin-payday few days ago
http://bitcoin-payday.com/?ref=Dpejkic1006They promise up to 3% yield, which is really surprising.
So I just invested 25$ to see if it's true. I already earned after 1 day 25 cent, since they promise 1% if you donate between 10-99$.
My question is how this works and how they make money.
