It requires the affiliate to buy a minimum of 100$ worth btc from coinbase to get a bonus of 10$, but the bonus is sent only after 180 days to both.

Oh yeah, I heard about that bonus from coinbase. But if so, then why would this site offer an option for 'Enter Address"?
They should be strictly requiring one to create a Coinbase account using their ref link or something.
Oh well, it's a thought. It would be great if it is indeed not a scam, but we see plenty of new ones cropping up and yeah, giving out $10 for posting a site link is indeed fishy.(must be a catch somewhere)
Anyway, @OP do update.
