And here you are right. Most users will not create their own nodes. Will this affect decentralization? We'll see.
Because of the lightning network technicalities, people can not go through the stress of the technical know how about having lightning nodes, setting up a channel and making use of noncustodial lightning wallets for it. Even on some wallets that are noncustodial, you can see a centralized lightning network on it in a way that only what the wallet users needs is the payment invoice, just as it was on Bluewallet before.
This is very funny, the fee for withdrawing to BEP20 is cheaper than the fee for withdrawing to the real blockchain in filecoin, it was mainly promoted because using BEP20 is cheaper and faster. It is difficult to find a faster blockchain than BSC because they are fully centralized, there are only 21 validators and these validators are all connected to Binance even if there is an error Smart Chain will be Halted.
I mean the fee for withdrawing filecoin is cheaper, yet Binance ki6ed about faster confirmation for its BEP20.
Do not trust what you see Binance doing. Filecoin transfer from noncustodial wallet to another noncustodial wallet takes some seconds, not more than 15 to 20 seconds. You can try that if you think that I am wrong. Although, its withdrawal on Binance is also fast but they are representing it wrongly.
