actually this is a problem of the work system. where all use work methods that aim to provide good service to users. but if it reduces the working power of speed, of course this is a new problem
Not sure what you're trying to say here.
The Lightning Network doesn't have much incentive to run on BTC itself due to the low rewards for hosting a node, it's completely different when you host a node on an already existent profitable masternode though, which also makes the whole thing decentralized
I actually have seen one or two posts in the pasts from someone sharing their lightning node income and it's actually not bad at all. Satoshis actually do stack up and if you've got a good node connected to a lot of channels, those micro fees add up over a day, over a month. Plus we're talking actual btc, which is a hundred times better compared to any masternode income.
