Like any other site, Primedice has its own limits for withdrawals. Those limits are different for each cryptocurrency that we support.
Of course, limits are something that can be changed from time to time but at any point, you can check those limits by yourself.
Minimum amounts for withdrawals are:
For BTC: 0.0004 BTC (fee is 0.0002 BTC)
For LTC: 0.1 LTC (fee is 0.0005 LTC)
For ETH: 0.01 ETH (fee is 0.0027 ETH)
For BCH: 0.025 BCH (fee is 0.00001 BCH)
For DOGE: 50 DOGE (fee is 1.5 DOGE)
For XRP: 30 XRP (fee is 0.0001 XRP)
For TRX: 400 TRX (fee is 1 TRX)
For EOS: 2 EOS (fee is 0.1 EOS)
Please note that the fee amount should be left on balance, as it is deducted from there.
As far as the maximum amount that you can withdraw goes, there's isn't any. You can withdraw as much as you want.
