The tokens were never really worth much anyways. You needed over a million to make even 1 Steem a day, which means you had to lose hundreds or thousands of Steem on average for the privilege. I'm not sure how smart contracts would have saved anything here. They didn't really steal much money, they just stopped operating and took away their bankroll.

As I said, perhaps you should look into makerdao and how it operates.

But to get you started on your journey; Smart contracts are programs operating on immutable blockchains... So yes, when properly coded, exit scam like this couldn't happen. Oh, since we're talking of gambling, check Augur as well.
