Woow is very surprising. I think it's a good deal for gamers, play then earn money.
I want to know how many coins we can get in a day?
Uhm? Gamers? Not so. I view this as a new kind of faucet disguised as logo quiz (or some sort) which is quiet creative and enjoyable. You should know that the bitcoins or any other coins that you can get doesn't worth that much. You can certainly earn a decent money which you can dedicate your time efficiently; and this is not one of those.
Basically, you play this for the sake of enjoyment and not earning.
