Yes, indeed! And the affiliate system is really smart too. It's so simple it's genius.
The smartest referral system I saw had just the affiliate's Bitcoin receiving address added to the url and then payments automatically sent out.
That is brilliant.
Yes pretty good, but leads to bitcoin dust, since peope often gamble tiny amounts many times.
Infact sometimes the fee is comparable to the referral amount. (yes people gamble 0.0001)
