only question i can answer is the profits are guaranteed in any casino

Most crypto casinos make money from in-house games, the slots by pragmatic are often rev-share and a smaller %.

In-house game max bet is determined by the amount of money you have in bank, since well... users bet against the house,

i can answer you a few questions if you need.

1. a casino should have as much as possible as reserv capital. but the casino should always go in the + if ur not ur doing something wrong but ofc make sure that ppl win from time to time if they will only lose they wont come back.

2. a casino should have as much payment methods as possible crypto/card etc. but try to do a casino without kyc. since most ppl are underaged or just simply dont want to share any infos.

3. as ur casino gets more players get mroe staff.

4. the win lose ratio should be pretty fair. but the casino always wins for example 40/60. but most casinos have it way more (in the casinos favor ofc.)

5. sure

How much would it cost to open a casino (illegal and a legal one)

Depends on what you're willing to spend on the build. There's source code built out there for around $500-$1000, but what you get is pretty basic. Or you can have a custom built for $10k+

If you want to legalize it, it's around $20k-$30k if you find a good country to fund the yearly gambling license, on top of the first time fees, etc. I would say $60k for the first year, then $20k every year after that.

Is a crypto casino a better option then a regular?

Yes and No. It's better for crypto if you keep it illegal. Regular casino is better if you're legal because you'll reach a bigger audience.

How many staff members should a casino have?

It depends on the scale. Realistically if you just keep a small online crypto casino. 2-3 people should be fine. A finance, a Dev, a manager.

How does a casino guarantee profits?

House always has advantage. and put p2p gamble, where house takes 5% off the earnings.
