I recently came across this article regarding setting up a bitcoin lightning network node which was highly up voted on Reddit
107 upvotes is hardly "highly upvoted"
https://www.reddit.com/r/Bitcoin/comments/8toaze/the_lightning_network_a_huge_opportunity_to_learnby this guy presumably from lightning labs
i can not find any affiliation between the author (Marc van der Chijs) and Lightning Labs. if i am missing it please give me the link.
unfortunately i can't answer your questions but i feel like he is exaggerating some stuff for some reason and people on reddit are also skeptical about it.
the thing about LN is that it is like a competition for lower fees. so if a node is asking for a high fee it will be ignored and the other nodes will be used with a lower fee. (the cheapest route will be chosen). so i don't think the returns he is promising are possible, at least not now with low number of transactions on LN. maybe in a year when there are millions tx/day we can see higher returns.
Yeah you're right, it's not that highly upvoted I just remembered it from the top at one point. I don't get what this guys motive is blowing his returns out of proportion or why he totally made up the "theoretical models" of 80% returns per annum. Very weird.
