Is there any fiat (visa card etc.) to bitcoin payment gateways for online webshops? Can only find the other way around, bitcoin to fiat.
You want people to buy in your store using Visa, but you want that value to be immediately converted to bitcoin and go to your wallet?
Personally, I think that this will be expensive when available
There are costs involved, like exchanges and mining costs.
Why dont you just send money to an exchange and buy bitcoin, after receiving your payments? This might be less expensive.
You can also add btcpayserver.org in your website. People will be able pay using visa in your current payment method but you can also add bitcoin.
