It's unavoidable imo. No matter shitcoins, fiat, commodities, stocks - everything better be convertible in Bitcoin and vise versa with ease. That's more liquidity and adoption. I believe many true hodlers heard about LN but never tried it, and now altcoiners have the opportunity to feel the speed and smooth of Lightning payments, and discover zap culture via Nostr protocol. How only-BTC exchanges and other artificial obstacles could help to orange pill more plebs? Often the real adoption of bitcoin comes after the disappointment in altcoins - why not to provide them easy way to change their shitcoins for satoshis?
