By now we know we got scammed by Magic Dice.
I don't quite get the exit, but maybe the business was just slowing down too much.
The key thing is that it wasn't that bad.
What we got scammed out of was the tokens and corresponding divident payments. But the magic dice formular was provably fair. Nobody lost funds from the game or depositing into the casino.
This is much better than a casino holding customer funds and running away with it, or an exchange getting hacked.
The next step
We need more than just provably fair transactions, we also need tokens with decentralized governance as well as apps that run natively on the blockchain.
This would prevent such exits from happening. Maybe steem-engine could provide such functionality, or maybe we need a different kind of blockchain.
