If you have 10000 and you don't have a single whale or big spender that's tough luck
Been there. Definitely promoted my reflink through shitty service that netted such.
As long as most of them are betting, then for sure, you will still get some commission for the bets they are making. I also have some referrals before in a certain sportsbook, I have only a few but I'm lucky to have bettors who are consistently betting and as a result, I was able to get some good commission.
the more consistent the bettors are playing under you, the better commission we will get from their bets.
