It seems most of the bigtime gambler is now prefer to use the cryptocurrency when playing because of its anonymity. If ever you want to experience a good gambling game its better to use fiat currency and go to the casino and play different games. I know in online gambling it is also accept fiat currency but sometime it takes a lot of time to deposit unlike in cryptocurrency that just take few minutes. For me, I will rather use cryptocurrency in playing gambling than using fiat because I want to secure my personal information.
But not all of the bigtime gamblers does use the cryptocurrency now. I highly believe they miss the feeling of going out to go the casino to play games. Because sometimes, the best feeling of playing casino is when you have other people playing with you as well and you can see each others. But since the virualization of online casinos and gambling sites now do already have a chat box for users, it makes the feeling real as well.
If we count these days maybe big gamblers are taking their foots step a little away with crypto currency since they are losing if the value if they are holding a huge volume on there wallets and for sure some of them shake there heads for seeing the current condition that's why sometimes I rather prefer to bet fiat since I can assure that I will not lose on volatility and will get the flat amount but in other hand maybe crypto is more convenient to use and also it's so different to play online and in real time since you will feel alone and be bored if you are the one who plays at home while in gambling for sure you will became excited since the ambiance and the presence of your opponent make the game more exciting.
