Sorry but the killer bitcoin app is digital gold. Bitcoin will never be optimal for payments until LN is operative.
Bitcoin (at today's exchange rate) works fine with the type of merchants who accept it anyway: online shops that mail the goods to you. For that, instant confirmations, or even confirmation in the next block just isn't needed, the goods will take a day or more to arrive anyway.
This is just ignorant. The high fees are causing havoc for both merchants and customers. Merchants don't want to send an order unless they know 100% that it is going to confirm. This is causing huge headaches for businesses that accept bitcoin.
