That's nice, is your referral link just coming only from your sig code, or are you also posting it on other platforms like socmed, blog sites, etc.? I looked at mine, only one signed up in the last 30 days. I have a referral that has already given me almost 0.017 total commission. Looking at my stats, I saw the referral wager. So that means, he also plays Multiply BTC or puts bets on betting.
This only from my signature links because I never use any platform to promote my referral links. Well, that still good to know considering I'm not good into referring or inviting but most likely I'd get it by posting on other boards here in the forum. If I spread it out more I think this may get more tractions. Good for you that you've got that amount of commission, though they are 10 who signed up only a few I got from it most likely they are just into free BTC rolls and not depositing bitcoin onto freebitco.in site.
