As Bitcoin price increases it is getting more difficult to reach the minimum withdraw threshold and more expensive cause the fees are higher now.
Have you considered to implement Bitcoin lightning network for payouts?it is instant, secure, almost free to use and a great chance to make more people starting to use it.
Faucetpay would be a great option which serves as a micro wallet. Many faucets send a few satoshis at a time to this site when requested.
