I have always preferred to bet with fiat currency than betting with crypto, though crypto deposits and withdrawals are easier and faster, I prefer to bet and gamble using fiat currencies because this is the currency that is going extinct, they are losing value as each day breaks due to inflations, so I will rather spend this currency on gambling than spend crypto.
Guess it is because you can easily determine the value of your bets right? But crypto casinos now have put an option to see our crypto bets via fiat. When it comes to the ease of deposit and withdrawal, it depends on the crypto but fiat is quick too for this. This made me gamble using fiats now. There is also no fee for it. If you are to spend fiat because you are afraid of inflation, then there are better ways of doing it. Why can't you just invest it on profitable assets for instance? Although gambling in casinos still lets you enjoy.
Crypto on the other hand is gaining much popularity and their value is grow rapidly as we all have witness overtime, I prefer to hold and keep cryptocurrency as an investment rather than spending it on gambling, because $10 worth of cryptocurrency lost to gambling today may be worth even $1000 in a couple of years, while $100,000 worth of fiat currency lost to gambling today may be worth $10,000 in a couple of years from now.
The money spend while enjoying is still priceless and what if we win? There are times that the value of crypto have increased by the time my winnings arrived in my wallet, so my enjoyment is much more.
