Most people who know cryptocurrency will choose using crypto for gamble because they see that when they used crypto, they can hide their identity from the government and the banks. They can play gambling on any site which has many options for the coin to gamble, so they don't have any problem with the process verification. I think in the future, the crypto gambling industry will become popular than the fiat gambling industry because people can gamble on many gambling websites without verifying their identities. And the best is they can play gambling in their home without going to the gambling places.
I doubt you can hide from the government or banks because once you get to win a lot, at some point you'll run in to the problem of cashing out your money. There are exchanges that don't do verifications but eventually it's getting less and less as countries are starting to notice the demand for cryptocurrency exchanges.
You can hide it through money laundering such as using mixers for your transaction become untracable since mixer's solution is to transfer such balance in a way that no one would know where it transfer that certain amounts. On the other hand, government are graduly tracking them down but it's still it's currently one of the best solution for you to hide your transactions online.
