Why you need a high roller account?
Is there's some bonus or high chance of winning if you use account that have past high rolls?
well i am not a high roller so i have no idea about that,but OP says there is then let it be not unless he has no good plan then that is another story so lets see if there is a possible Good samaritan that will give him High roller account.
I don't think that you would really get a high rollers account for free because it is also their name that is at stake on their account.
Who knows what you might do on their account at primedice those high rollers could borrow some money to some members because of their reputation at the site,
So it would be dangerous to give out their personal account loaning money on gambling site isn't new so they would surely avoid giving it out specially those well known gamblers.
I don't think loaning in gambling site is allowed. I know there few high roller that will dump their account and make a new one for another session.
not totally Loaning but what He meant is asking someone to share you amount to bet since High roller accounts mostly have friend in gambling sites and also trustworthy (in some manners) but yeah lets see if there will be a Donor of account here.
