Here's a question - if you open 5 lightning channel with 5 UTXOs, each with a different 'cost basis' themselves and you start receiving sats (say from Stacker News...)

Do you have to keep track of individual sats going to each individual channel? Sometimes if you generate a receive invoice you don't know where exactly the sats are going, the (Lightning) wallet software does this for you.

And remember that the tax authorities want cost basis 'per utxo' but... Lightning is based on channels not UTXOs. So you have to track each channel, take a screenshot, for each one for record-keeping?

Why aren't people asking these types of questions? Why isn't there clear guidance?
