Crypto money helps gamblers to be easier playing gambling. They can transfer and put the money to the gambling games anytime without the needs of the third party. Besides, the gambler's identity will remain anonymous in this way. Yeah, they may be just several advantages, there are other ones for sure.
Yes, that will be the reason for gamblers to choose crypto gambling. They don't have to wait for a long time to send the various coins to the gambling game. They only need to buy any coins they want, and then send it into the gambling website, and they can start to play any games.
Besides that, they can hide their identity like above me said so they could feel safe to play the game without anyone knows. They can play in their room or in some places they want while they can meet other people.
