The fastest dice sites just mean you will lose your money the quickest. That's why sports betting is ideal for gambling, as each 'roll of the dice' lasts two hours.
It's a strategy of a dice player can be effective for you but not with others. Dice can be ideal for others but not for you just like your opinion and I do agree about sports betting.
I'm with you on that but the preference of op who's asking is about dice.
@op check the reputation of duckdice just like what everyone is telling you. You can try the other suggested reputable dice site but think about it first before trying them.
