1. Say I have a payment channel open with a friend with a 1 BTC limit.
What happens when I want to increase that limit? Must we close down the payment channel entirely (settling all balances on-chain) and opening up a new one with a higher limit of funds?
2. How are fee's charged for each hop? Nodes just set a fixed rate? A %? Is it resonable to think fee's on LN might drop to zero if only a handful of altruistic crypto-zealots decide to run well funded LN nodes to funnel all zero fee transactions?
We know TOR works and that has zero fees. So I would assume it could work for BTC as well. Right?
Let's please avoid any argumentation pro or against the Lightning Network and focus on the two question.
Thanks (:
