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 doesn't have any built-in wallet, you have to integrate payment gateway on it and process transactions through your partner bank.
So in overall as I understood, you have to deposit bitcoin and then system will automatically convert it into bitcoin? Am I right?
Or you list bitcoins as a product and then customer pays via visa/mastercard and bitcoins are automatically sent from your wallet?
