Its truly important, anonymity is a crucial feature, many people don't like to expose themselves in gambling and anonymity could help the gambler from restricted country to play the game, and crypto gambling is famous because of its anonymity, so this feature is a must in crypto gambling
Yea, its really very important. Especially with the bad reputation on gambling, no gambler would be glad to be publicly known to be a gambler but instead would enjoy to play secretly why they can deny the game openly and another vital point is for the benefits of people gambling from countries where gambling is prohibited.
I have friends I have known from online casinos and most of them play from countries where gambling is illegal, they are able to do this by using a hidden vpn and am sure its truly helpful, I honestly think for as long as gambling remains, gamblers would always prefer to keep their identity undisclosed
If theres any reason why people like to keep their identity safe in gambling, I want to believe it should be more or less for safety, not because of whatsoever reputation reason you mentioned above. This has nothing to do with gambling because if the reputation of gambling was that bad, then we wont be having more gamblers by the day
Please note that gambling secretly in a country where gambling is prohibited is still disobedience to the law. Its simple, if your country declares the game illegal, then stay off, theres no point going through the back door to play. So I feel your friends are only taking a risk that is not worth taking at all.
