It's nice seeing that there's always some sort of enthusiasm for a new invention. The intelligent part of this innovative technology is that it incentivizes you to think likewise.
I think that one of the problems Bitcoin will be facing over the long term is the aftermath of some disastrous events. I'm talking about events leading to internet blackouts or power cuts.
I think that's fearmongering.
Everything is built to operate online; the whole world moves (and has already moved) their businesses to the internet. There are stores which only exist in the internet. Part of the education system is done from distance. The communication etc. Saying that one of the problems Bitcoin will face is this kind of disastrous event is trembling the least.
Lots of other events will occur in such scenario which will affect the economy much worse.
BTW,
lightning doesn't always require internet connection.
