BChat can be switched off in Settings, so people who find it distracting can use that.

BChat IS adding BCH to NOSTR, that's the whole point. It runs on NOSTR backend. Yes, there are thousands of apps, but if the BCH community does not have its own venue for discussion than it will 100% guaranteed eventually be censored or manipulated by outsiders - that has been seen over and over again. Also, BChat drives non trivial transaction volume, even with its small community, which is something the BCH community desperately needs to find a way to do.

I do agree we need to find ways so that it doesn't become a circlejerk of BCH users telling each other how great they are. No free tips stops it being about beggars, but we need to raise the discussion further than BCH alone over time anyway.

Multisig, vaults & so forth for security are also something we are thinking about quite seriously. But it's a big development effort, may be superceded by the imminent XO templates, and it's only relevant to a far smaller pool of dedicated users (not the average person being onboarded to BCH).
