As a business owner, this is definitely interesting ! For myself, I'd love to see smooth, cost-effective website integrations that allow people to pay with a variety of popular cryptos, and then have them settled in HBD.
The issue is that there are all kinds of e-commerce platforms people use, so plugins for the more popular platforms (Shopify, Big Commerce, WooCommerce etc) as well as an API-type integration for other platforms (e.g. Bluepark, which I'm just switching over to) would be ideal as well as. But any data interchange would have to be banking-level secure and provide enough of an audit trail & reporting to satisfy UK tax requirements.
