A simple honest question, I am taking for granted that your strategy works, although I have my doubts, why don't you get all these referrals for your self and make a lot of money, rather than trying to sell your service here, I have bought before services like this and they never worked maximum the refs worked 1 day, I tried for neobux and other PTC , but should be the same for a bitcoin casino, if they are not interested they will not stay active.
I am doing it, i got 1000+ referrals in some bitcoin casinos, and I had 5000+ in some cloud mining sites but they went bust later (although I still made profit) and they all generate nice comissions for me. I earn about 10% monthly with this method, everytime I reinvest, however it needs 2-3 weeks to hit ROI.
I don't know what services you bought before but they probably just used bot refs. I am providing real referrals, and I guarantee the activity of the referrals.
The accuracy of my refferrals is 1 in 28, so on average 1 out of 28 ref will guaranteed stay active.
So 1 ref costs 0.004
BTC, but you will get 28 refs of which 1 will be active and the rest of them are bonus. If the rest stays active, then all the better but atleast 1 out of 28 will always be active.
