Yes, they're offering each referral 100 USD but it will be unlocked by wagering from them (it has rules)
You can visit affiliates on-site
I'm promoting the site and playing for months with a bonus they're locked my account. why should i promote the site? i can invest that money on the site i didn't make that deposit on the site it that a mistake? or I'm promoting the site that is a mistake?
If I deposit in my account will be safe? what about the deposits I have made a few months back, there didn't see that??
If there's a wagering requirement for the referral bonus to be claimed, why would they lock your account? Did you pay people to sign up only or complete the wagering requirement too? If so, that's not going to be good for bc game but they haven't set such rules for the referrral deal I think. Did you try to get them responsed here? Please PM the bc game representative of bitcointalk and asked him to reply here.
