If you are telling that for preventing the chargeback then that will not be helpful . Because if you withdraw your funds and buyer perform chargeback then fiverr will cut the chargeback balance from your fiverr balance .And if your balance is zero then your balance will be { (-) the refund/chargeback}. So I think it will not work as you think .But this will be helpful for the new ,level one and level 2 sellers because we will get our money fast than the current period . 😀
