📝 Original message:Most solutions only work with a single Bitcoin address (terrible for
privacy, and also potentially a security risk) or xpubkey (also terrible
for privacy).
I think the best solution here is some kind of store-and-forward server,
where you trade a little bit of privacy (to the server, that is), but get
the convenience of using (for example) an email address as the account.
I like for example BIP75 for this, and I hope the community can work
towards a solution like this. This could potentially work good with LN as
well. https://github.com/bitcoin/bips/blob/master/bip-0075.mediawiki
