From the title I originally assumed you earned 1 BTC gambling, but either thats quite some earnings. How much exactly does an affiliate have to gamble to earn you 1 BTC anyway?
Yes, the title is misleading should change it to like "I made 1 BTC in one night from a gambling affiliate program".
He should be very lucky to earn such a huge money through gambling affiliate program because earlier I also got some referrals but never reached withdrawal limit yet.
