I mean the LN can bring plenty of new concepts of payments to the table but are they really necessary and benefit the average joe?
I like how you remain neutral here. I'm sure that by the time LN is mature enough to handle these uses, we'll see a whole lot more coins being added for much wider exposure because there is more than just Bitcoin.
We have more than clear evidence that the services opening themselves up to a large number of crypto currencies are doing way better than their competitors just sticking with Bitcoin and Ethereum for example.
We might even see tokenized fiat currencies being easily divisible and transferable be used for micro payments. Bitcoin's progress motivates the rest to follow and you can be sure that they will follow.
Average joes don't care about decentralized currencies, they just want to use money in the most convenient possible way.
