You shouldn't be advertising betcoin.ag given their current situation and how they handle problems/themselves.
That being said, I would advise everyone else being enrolled in that campaign to do the same, drop it.

WARNING: Based on recent evidence players are advised to proceed with caution when playing Betsoft games offering jackpots. It would be wise to play at reputable Betsoft casinos only since it appears the individual casinos may have control over the frequency of jackpots.

WARNING: avoid Betcoin.ag since they are using phantom and/or imaginary Terms to withhold jackpot payouts.

Rogue Casinos: the worst of the worst

Betcoin.ag
Betcoin.ag is one of a new breed of casino that operate solely using crypto-currencies such as Bitcoin. In mid 2016 we were approached by Jason, a player that claimed that he had been stiffed of a million mBTC progressive jackpot payout on a Betsoft slot, The Glam Life. Jason won the jackpot with five yacht symbols across the middle payline. Or so he thought. Instead he was paid a 1000 coin win and told, after several changes of story, that he didn't qualify for the jackpot because the winning spin occurred during the game's free spins bonus round. This was not documented in the paytable at the time, and after the controversy Betsoft later updated the game's paytable with a poorly worded statement that attempts to state this exception. The bottom line is, he was ripped off from a once in a lifetime win.

While the issue was no doubt caused by Betsoft, either through incompetence or malice, Betcoin.ag did itself no favours in its handling of the matter. While other casinos were dropping Betsoft games altogether after our investigation into their jackpots revealed several irregularities, Betcoin continues to offer Betsoft's crooked games. They instead told the player that they couldn't do anything, its all up to Betsoft and they are just a poor innocent intermediary caught in the middle. Eventually Jason was paid off with an amount that no-one will divulge and forced to make public statements proclaiming his love for Betcoin and Betsoft. In other words, they paid him to shut up and stop complaining about his rightful win. Betcoin.ag is not licensed or regulated by any recognised authority and they have demonstrated that they are a rogue casino willing to run crooked games. Avoid.
