I recently found this game:
https://farmsatoshi.com/?ref=37368Satoshi are the in game money and you can pay it out, I am not sure, how much you will earn at the highest level. People are talking about 100.000 Satoshi a day.
But to achieve higher level you must make more referrals because that is part of a mission. Without referrals I think you can only reach level 7 or 8 if Im not mistaken . You can earn only dust satoshis at that level. It's better to play coinflapper than farmsatoshi. You could try it too OP.
