To me, running a financial market always seemed more profitable than running a casino.
But in crypto, is it the other way around? Are casinos making more money than trading platforms?
You can't really tell, both have different business models and ways of making revenue, and both are really profitable businesses, given they have enough users using their platform on a regular basis. However, there is one big difference that I see between both models, which I think is an advantage for an exchange platform and a disadvantage for a casino.
See, in a casino, when someone wins a big amount, the casino has to pay them from their bankroll, regardless of whether they have made that much that day from other users' losses or not. For example, if someone manages to win $500k as a jackpot or something, while the casino itself has made only $300k in revenue that day, they will be at a loss of $200k for that day, even though they will surely recover that money soon, but it is what it is.
In an exchange, almost everything is done using the funds of their customers. Even if someone is getting liquidated in futures, their money doesn't just go to the exchange, but they are given to someone who made profit on the other hand. Like, if you have shorted Bitcoin, and I have longed it, if you get liquidated, I make profit, so the money from your liquidation is used to pay for my profits.
