I usually not consider the opinion of gambling with Bitcoin as smart enough normally but seeing that it's the new innovation at various casinos, I can't say any more but to allow people who wish to give it a trial, Bitcoin for me is a supposed investment and so I see no reason why I should channel it into gambling where I stand a big risk of loosing it.
Ofcourse moat of the casinos may now stand to be a whale, they have a good number of btc in their possession, we have the likes of other big casinos here on the forum, they all have got a good holding that enables them run the crypto casino because they need a substantial holding to be able to run such so truly they are considerably whales.
If you buy and hold Bitcoin for investment, of course, you wouldn't deposit it into a casino to gamble. But if you have Bitcoin for transactions like you would with money, I don't think it's a problem to deposit Bitcoin for gambling. I also gambled with Bitcoin in the past. But now I use stable assets like USDT. Bitcoin is becoming increasingly valuable, so collecting it for the long term isn't wrong. Casinos accept deposits in other ways, so we can still have fun without losing Bitcoin.
