I think yes they are, because they are also dealing with crypto. Obviously an increase in crypto price can mean more profit for them. Another plus thing is it might lead for them to gather a lot of customers because people are excited about their profits and one activity they can think of to spend with it is by playing gambling in a crypto casino. 4 topics about $100k BTC price seems too much already but I think there actually more than that, that I see here in our forum. Yes, topics are like that.
It usually questions the readers and the readers can give a response if what they think of the question. Casinos are a business, so there must be a change. Either they are losing or profiting. Whatever their status are but as long as they can still sustain the casino, then yeah it will still be a business as usual and it doesn't also matter if the BTC price is skyrocketing or dumping.
To answer this question , we will have to get statistics or data that gives a valid analysis of the situation. I did a brief search but couldn't find anything reasonable. But with the rise of Bitcoin to this price, gamblers who are hodlers will have more money to spend if they sell their coins. Maybe it might make them increase their gambling budget which will be beneficial to casino companies. However, I have observed an increase in casino signature campaigns in the forum since the bull run this might be a sign that the season might be benefitting casinos.
As a gambler myself, I find it hard to save or invest. So I'm thinking that successful people like that, may not really be into gambling. The increase in casino signature campaign, might only be a coincident to what is happening in the BTC price now. And maybe the casinos actually think of the possibilities you said there earlier. So they just take the risk. If this goes well, then congrats to them. That shows that the risk they take is really worth it.
