Your wager determines the hourly reloads. If you buy a Primedice or Stake account you will not receive this bonus unless you have the wager to match it so this is misleading. Another reason to not buy accounts is the original owner can recover the account after you deposit.
There's actually no reason to buy an account when you can just make your own because everything is wager based for bonuses.
Do NOT buy accounts for anything you plan to deposit money on for any website
