One thing that I really like is the "Fast Transactions, almost instantly"
It will not run as Ethereum network, where you have to wait for many confirmations, which sometimes takes a really long time?
Have you tried using any of the products to confirm the transaction speed? I assume it will be faster as they are an independent blockchain.
I think in the country I live in I can not test the app yet. For that I have to wait until 2019. But maybe there are already reports from someone else?
