What are the minimum payout thresholds?

The minimum withdraw threshold is 0.01 BTC for Bitcoin, and 0.1 BCH for Bitcoin Cash.

The threshold is per address (not per sub-account balance).
If multiple sub-accounts are set to withdraw to the same address, the total amount for all those sub-accounts must add up to above 0.01 BTC or 0.1 BCH for the withdrawal to trigger.
