Re: [Primedice.com] Bingo Competition! - Win up to 4 BTC Each - Positive EV Gambling
Heh i missed this one. WIll you have similar promotions in near future?? I need to put in work my account with over 500btc wagered 
In the first post it says this.
So most likely there will be giveaways quite often.
"Upgrade to Primedice signature and avatar to enjoy exclusive benefits in this and future contests and giveaways!
You must not switch your avatar & signature around. Primedice hosts giveaways often so you will be entitled to benefits regularly. People who do not hold the signature & avatar for the duration of the contest (Or at least majority of it) will not be included in the bonus. Once you set a PD signature and/or avatar, please leave it."
