Has anyone looked into Paybear? They have a fully functioning service (provide a payment gateway) for ecommerces and are on the verge of launching their token, so basically all the current webshop owners who are already accepting the big cryptos with their API will automatically be able to accept the token as a payment method, does this sound big?
You have services such as coinpayments which have support for vast amount of crypto already. Problem here is that however you are relaying on 3rd party service when in reality you don't have to. These services are okay since they host nodes and all that but with free APIs and a little of work you can create your own version of payment system and without the need to pay somebody for it. But easier way is to go with such payment services as they make it very easy.
