Yeah LN is pretty sick. I haven't used it myself but I've watched videos of people using it and they hit the button and literally a second later (or less) the other person has received the money.
As a network protocol its got some tradeoffs and still seems to need work and improvements that will hopefully hide some of those tradeoffs, but in terms of being able to send cheap and instant payments with Bitcoin its pretty amazing.
Bitcoin base chain is great for storing wealth and moving money around and buying things on the internet, but LN makes Bitcoin work for buying things in person where you need that instant payment.
Yes. Also, how long has LN been around? I think the first transaction was only in 2019... so it's just a baby, and it already performs beautifully... maybe a few kinks to work out, but it just needs a few years and it will only get better.
I believe it was January 2018 when it officially launched, if I'm remembering correctly, but it was in like super alpha stage for that first couple years. Even now it seems like it is in like a beta stage, it works but there is still plenty of development to do for it to be super reliable and easy for the average person to use and not have occasional issues.
