There are no charges for receiving funds in HKD or USD from Stripe. Similarly, there are no charges for receiving funds in HKD from Paypal Hong Kong.
It is important to note that the withdrawal of funds from payment gateways will be in HKD or USD, as these are the default currencies of the respective payment gateways, such as Stripe or Paypal.
Please note that Stripe's policy for payouts in Hong Kong only supports HKD and USD currencies. To receive payouts in USD, you will need to enable the USD payout option from your Stripe account.
