What I think is that the casino owners must be anxious, the more value the BTC has, the more everyone plays, of course the thing with the fees is another thing, however with all the adrenaline of seeing the BTC above $100k this is something great for everyone, both for the holders, the BTC holders and for the casinos, they know that the business will increase in clients, in plays, in everything, so it's a win-win for me, of course that's my thought, I don't have a casino, but wherever I did I would think that way, I don't see any other way.
I'm not sure about it, maybe they will continue to play, but I do not think that they are going to used their BTC as obviously the price is going up again and we are on the 6 digits. Also, casinos are only anxious if some big whales have won, not the price going up as they also have a stockpile of BTC and so when the price increase their holding and profit also goes up.
So in any case, casino are still going to win no matter what, and as gamblers we really have to think twice to used our precious BTC or just hold on them and uses like other altcoins or even USDT so that we can still keep on playing.
