This is a common question we've received since launching our Authorizing Selling program with Stripe.
At the moment, Stripe Balances and Gemini Balances cannot be transferred between each other. You can transfer your Account Balance to your Stripe Balance to withdrawal, but cannot transfer Stripe Balances back to Nifty Gateway.
This is because when you submit a payout through Stripe, they will begin processing the payout immediately. When you withdraw your balance via Stripe, those funds are en route to the account you have on file with Stripe, which you can see by navigating here and clicking Open Dashboard.
