I prefer money, strongly. When you gamble with money, you are *risking* money for a chance to win money. It is always a losing proposition. But it’s not the same as *spending* the money. If I walk into a casino with a $50 bankroll, and I walk out of the casino an hour later with $40, then I’ve had a good night. Cause losing the the money will be okay for you but on the process that you won as will you'll enjoyed more than coins, you won't have to trade anything at the moment.
But gambling with coins will involves of spending more money on the play coins. Which have no value or gain at the moment (if they have value, they wouldn't be play coins, they do just be different kind of currency) So, you’re paying for the privilege of risking something of no value in the hopes of winning something of no value. That doesn’t even count as gambling anymore; that’s paying a fee for the privilege of keeping score on a random number generator. What's your own opinion towards this?
I don't get what you are trying to say with that last whole last part. People who play with cryptos, already own cryptos. They don't buy it for that purpose, at least not anyone that i know of. And what do you mean IF they have value? How wouldn't they have value? What kind of cryptos are you talking about? I find it weird, because it sounds like you don't know much about cryptos, yet you are in bitcointalk talking about crypto casinos.
But answer to what i prefer is it depends. Crypto sites have fast withdrawing, no matter if it's weekend or not, and in theory i like to support sites that allow cryptos. But most, if not all crypto casinos that i know are outside EEA, and i need to pay taxes for the winnings. While winning inside EEA with fiat money casino it's no taxes for me and just less of a hassle in that way.
And some would call just holding a midcap crypto in a casino a gamble, as their value in fiat money could just rise or drop over night.
