It's just that talking about LN, I'm curious why currently there are still many people who don't try using LN? Am I wrong in retrieving the data? Or is there something that keeps people from popularizing the use of LN? Because honestly I just found out about LN some time ago and what I know is that the network is much cheaper than the main BTC network.
There is nothing wrong with using the Lightning Network, but for a one-time transaction, it doesn't make much sense. If you and me, for example, transact on a regular basis, then LN is useful. If one of us is only supposed to send BTC once, we aren't saving anything in case we have to open and fund a channel and then close it afterwards.
