Up to 3 % return on capital

[Ryou]

Hello guys.

I met the website bitcoin-payday few days ago

They 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.
