We used different deposit methods and there was a lot of fees in the past. What is the link between crypto moneys use and online gambling?
You said it yourself, there were a lot of fees before and for people who still use fiat fees are still high. On a side bitcoin that had really high fees for transactions, there are a lot of alts with very cheap transactions. With crypto we have some kind of anonymity, like others already stated.
Do you need any more informations why crypto gambling is the future?
Online gambling is industry that started to grow just in past 10 years more or less, and that industry will continue to grow, fast in my opinion. People will have a chance to choose to gamble with fiat or crypto, and who ever is aware of advantages of crypto gambling will choose that.
