Cryptocurrency casinos provide an easy and safe gambling ecosystem for both gamblers and casino owners.
Some of the benefits are:
1. Anonymity
2. Easy and fast Deposits
3. Better Odds and Provably fair bets.

On the other hand casino owners are benefited due to the phycological fact that gamblers are not betting in real money units such as 1 dollar 2 dollars.
When betting in unit portions you don't really understand the amount of money you are betting. It is like you are betting less because people's mind only correlate the numbers between them and not the Dollars with Bitcoins or Trons, if you see my points. Having said that, cryptocasino owners are getting bigger profits from crypto bets.
