Oh, not at all as they were still new when I signed up on the site. No bonus but reflink which gave wagering bonuses to the referrer.
So basically, those who created an account using the bitcointalk code is nothing of use and only the referrer will receive bonus rather than the one who created an account using the bitcointalk code. Am I right?. I also think that the bitcointalk code used to create an account will give you bonus when you referred a gambler using your referral link or code and since the account is created with the bitcointalk code then you will receive wagering bonuses.
Hey, there is a +5% deposit bonus as I've mentioned in the first reply to @notblox1. +100% deposit bonuses will be introduced next month if this is something you're looking for. On the other hand there are many other promotions for already registered players that in my opinion provide more long-term value

As for the referral program, you can find more information here
https://thunderpick.com/en/profile/referral (you've to log in though).
Long story short, you can generate your own code and link (using any of those will connect referral with your account) and receive a % of their wagers (a sort of referral rakeback

).
There is also an affiliate program for any of you interested - more information available here:
