I looked at statistics, the usage went up around last half 2019 then tapered off. looks like not that terrribly popular although not died.
IT seems stagnated. Are there benefits starting to weigh in?
I wonder if major wallets are supporting or starting to support LN?
LN is definitely not stagnant or dying,but it's definitely not growing rapidly.BTC transactions on the chain are fast enough,so there's no need to such offchain solutions like LN right now.I don't see any major benefits of using the Lightning Network right now.Maybe when the Bitcoin Core blockchain gets stuck again and the overall transaction fees and confirmation time increases,many BTC users might start using LN for a while.
However,I don't believe that the die hard Bitcoin Core fans will ever adopt LN.
i would consider myself diehard bitcoin core fan due to extensive studies I made in the past, but I am for LN, if not for LN, how are you going to solve the 7 transaction / second problem?
