Hivepay really is a great addition to Hive, and creates a lot of use case, one thing that just struck me is swap.btc and swap.eth too, if enabled in Hivepay the Hive blockchain just solved the scalability of sending and recieving Bitcion and Etherium with 3 second transactions, all available for merchants who wants to accept those on their sites but not the hassle of waiting for the native blockchains to complete the tansactions.
