As far as I am aware one of the only ways to actually stake in a relatively secure way is to do it with a very established coin, like Ether instead of tokens.
I can't call it secure way. Risk the same. You staking real crypto (eth) for some tokens, which if site/service disappear will cost zero.
This risk is involved in any cryptocurrency however some crypto is less risky compared to others that are riskier. However, when we talk about gambling casino tokens, it's easy to judge them as we know how much gambling casino is popular and what is their progress. Based on this we can increase or decrease our accumulation of gambling site tokens.
