you're going to send bitchat via bitchat to another user who doesn't have bitchat you mean?

yes, would be cool for a bitchat user to tap "send bitchat" and drop it onto another device without it, like an airdrop but a "bitdrop" Maybe you can share an apk another way from a phone to another phone but may be simple for not techy user to share the app when you can't download it in a grid down.
