We are continuing to research this matter in great detail,
we had to convince the CEO of Betsoft to make a payment here
It sounds like to me that you have already done more then enough research on the issue.
And no, I would not trust any other online casino that still uses BetSoft games. However the other casinos did not direct a player to a game in which the player won the jackpot but did not receive the full jackpot amount. This player went to "betcoin.ag" when they were playing this game, not one of your competitors.
Any casino that does decide to continue running BetSoft software also has the option of paying out any jackpot that BetSoft does not honor that should have been paid out -- which would be the right thing to do.
