Its not easy to get referrals for Freebitco.in .Almost everyone here joined it

And each person has also like 20 refs

Yes, but if you aren't getting paid from your current referral, simply create a new address, and sign up under my referral to get paid.

I think creating multiple accounts is not allowed, and will only get you banned.

That I did not know, even if you only use 1 of the accounts?
