The idea is so fantastic and as it was given in 2017 , so now it can be more good with the growth of technology. Hope one day it will be implemented worldwide.
Lets hope the lightning network is NOT implemented worldwide. It's not a solution at all and gives just back power to big financial institutions and power to companies like blockstream who toke over bitcoin, making it slow and bad to make money out of it. Wake up, bitcoin is not anymore what its used to be or what it should be. BTC is not Bitcoin.
Running an payment hub as an normal person does not fit current worldwide laws and that makes it illegal for you. That's why Bitcoin as it should be, is not illegal because its peer-to-peer.
As soon as you transfer funds for another person to another, you need a financial service license. Which means in other words couple millions of dollars, lawyers and much more.
Besides that, literally no one is using the lightning network right now or wants to do so. There are about 20 merchants worldwide accepting the lightning network. And I'm not talking about big merchants, I talk about some student resident in south America and ski hubs in Italy.
All those lightning fanboys don't even get what it really is about.
