Oddbean new post about login | logout Wouldn't you say custodial lightning is a form of ETF?
Yes, but the lightning network has different trade-offs. People are more likely to use ETF's for retirement. I would never tell someone to keep their retirement on WOS. Keeping 100,000 sats on WOS you plan on spending anyway is a different story. I used my own self-hosted my own lightning address before, but payments failed all the time. Because of this, sovereign lightning addresses pose more risk (not recieving zaps) than using custodial lightning solutions.
