This is the same campaign, we just needed to create a specific topic.
We apologize but can't process duplicated FREE BETS.

I have credited your account. Additionally as you have a pioneer account (email and not username), I have also updated your account username to "tonyq"
From now on you can use both your email OR email to login.

Have a good day.

If you want true unlimited limits & profits, it can only achieved on a sports betting exchange. A bookmaker will always cut yourself off when you start profiting too much..

Your account was already credited more than 24H ago.

We have changed the pool because we had to remove the FreeBet References on this topic so that it could remain on the gambling zone.
Another topic was created on Games & Rounds about the freebet.

From now on use THIS LINK to talk about FREE BET campaign and related.

BetBTC FREE BET

We will be giving to each Sr. Member or higher the equivalent of 3 x Minimum Bets as Free Bets (mBTC3).

All you have to do is create an account on BetBTC (if you don't have already) with the same username as you have here on Bitcointalk.
The Bitcointalk account must have at least Sr. Member Rank to be eligible for this FREE BET:

• If you are Sr. Member or higher, we will attribute you a 3 mBTC FREEBET.

After you create/have it, all you have to do is post your username on this topic, claiming your freebet.
We will then manually verify the account and credit the correspondent balance as soon as possible.

The bonus must be wagered at least one time (3mBTC) before a withdrawal is requested. Minimum withdrawal conditions apply (regular rules).

UPDATE:

You will have to leave a short review / feedback / suggestion on one of the following topics, before we process your freebet withdrawal.
