Don't expect anything as we have no idea about the intentions or motives of the casino owners, few years from now.
So to play safe, bet small if you really want to bet on some lines here.
For long running items, if you are not comfortable, then don't. You can't blame them anymore if they are gone.
But hopefully, the futuur team will be active here as they are offering unique betting platform, wherein, some players do like a change of gambling atmosphere.
This is not specifically about Futuur team, however putting all of your money into a casino and using them as a wallet would basically be the perfect method to lose all of your money very quickly to an ill intended place. I would trust exchanges more than I trust casinos and I do not keep my coins even in an exchange, I rather own a hardware wallet and put them there but even if you do not then non-custodial wallets would be even better than putting somewhere else. Remember "not your keys, not your coins".
However if you would like to gamble then the best method would be depositing after you lose what you have, put in 50 bucks, lose that, put another 50 bucks and keep repeating that instead of putting it all at once. This way you would be guaranteed that if anything happens then you would not have too much money in the casino at anytime.
It is not 50 in 50 or any other amount, there must be a prior plan. You should always understand the action of a deposit in a casino as a risk investment, as you would with any other type of asset.
The plan includes the size of your bet, the benefits you want to achieve and consequently the strategy to follow, nothing can be left to the good faith of luck, even in what type of game you are going to place the bets, when you add everything that, you get the correct deposit.
Now, if someone who is going to make a deposit in a crypto casino has to explain him the basic theory of safeguarding their assets, things start very badly.
I think, every gambler has their own strategies on how they fund their account in casinos. But you have to make sure that you are at least securing your funds by not storing your coins long term in those casinos, just like in exchanges. Better send when you play, and withdraw it afterwards. At least, you know if in case there will be problem, you will know early. And you won't be depositing again.
