It sounds as if you are making changes to Bet King that could potentially risk the funds of the investors - ie. you're switching to the MoneyPot model. That includes exposing your investors' coins to games with less than 1% house edge, which they didn't sign up for. It would be better in my opinion to require the investors to withdraw from the existing site and deposit to the new one. That way you are sure that they consent to the changes you are making.
Actually with they would have to withdraw and redeposit using the Money Pot account system.
...Still if people are gambling with pretty nice amount of bitcoins they would'nt be as comfortable as they would be on PD or JD cause the owners carry their honesty by paying thousands of coins when they had to .
However , nothing is perfect in the beginning and let's see what they provide to the gambling community.
BetKing.io has been running for over 2 and a half years (as pocketrocketscasino.eu) and has paid out many thousands of Bitcoin, there's been 35,000 Bitcoin withdrawn in the last year.
We've had players bet hundreds of Bitcoin at a time, up to 1300, and have had many withdrawals over 500, some over 1000.
We've had the biggest Bitcoin investor bankroll for over a year, 5000 at peak, currently 3000.
I think it's unfair to say it's not as trustworthy as PD (considering we look after more player funds at any time than PD) or JD.
