The main Bitcoin network often crashes due to the density of transactions, in 2017 I carried out Bitcoin transactions for almost a week to get confirmation 1. Bitcoin lightning network transactions, even in small amounts, can be done in less than 1 second, with almost free transaction fees. Bitcoin lightning network users will only be charged transaction fees when the payment channel is closed and will be adjusted to the current Bitcoin transaction fees, so the Bitcoin lightning network will be very suitable for users who frequently carry out Bitcoin transactions.
