It allows you to sell your BTC for fiat, but how (and where) can you withdraw them afterward, the bank only? Does WooCommerce have some kind of built-in wallet?
As for the fees, the website you're currently using is known for overestimating, use
Coinb.in instead.
WooCommerce has a lot of payment gateways integrated. This question is out of my plugin scope. This plugin just creates a new WooCommerce product type to sell Bitcoin, and sends it to the purchaser automatically after payment is confirmed.
Thank you for the Coinb.in suggestion. I failed to find an API here. Can you point me on the API please?
