Agree that being anonymous makes it more comfortable especially in the world of gambling, maybe this is also the reason why many players who hide their usernames at the casino, can see on the list of winners of the $250,000 lottery
https://roobet.com/winter-wonderland-raffle there are 25 winners and only 8 players whose usernames are displayed the rest are hidden. The winners have hundreds or even 1.5Million tickets, which means they use big funds to gamble.
The most of the players want to remain anonymous while playing on crypto casinos and you could hint it form the KYC discussions we had on the forum and most of them prefer casinos without KYC but still there are some who are comfortable with level 1 of KYC also.Those who have such high number of tickets are really gambling huge amount of funds and we know the whales are playing on each casino.
