For a large number of users, LN is too complicated to use. At the same time, I am talking about those who are not Bitcoin beginners, but also those with crypto experience. If there is no significant change, I don't see that LN can gain significant popularity. That's why I don't see any solid reasons to implement and emphasize support for Lighting.
Lightning network is not complicated. Probably you have not used it before is the reason you think it is complicated. Or because of the previous wallets that support it in a complicated way. If the bitcoin mempool is not congested try Phoenix, Zeus, Aqua or Muun and see how simple the wallets will open a channel for.
I have been studying lightning wallets for few weeks ago and I made this topic for it
Lists of open-source bitcoin lightning wallets. You can see the ones I said are good for beginners. Just let the mempool become less congested and try any of it.
You are right; the commission costs situation seems quite unstable, especially after the halving period. Currently, the situation has normalized, but this will only last until the next wave of multiple transactions. In this sense, the Bitcoin Lightning Network appears more attractive. Many CEXs are already organizing its acceptance. Monitoring also includes exchange services for various directions with Bitcoin LN.
I can see lightning network on exchanges like Binance, OKX, BitMart. Coinbase recently is also now supporting lightning network. There are still many other exchanges that has it. If you want me to name them, I can name them here but I do not think there is any need for that.
I am not going to lie. I am one of those users who failed to use LN even when it has been around for a long time. In most cases, i just end up paying the high Bitcoin fees. Anyway. it'd a good one for those who know how to use it.
Why not just try it with small amount of bitcoin? You will like it. Try and read through my topic by clicking on the link I have on this post. It is not good for tmhuge amount of money but it is good for small amount.
