I'm a bit confused about what this statement means:
Since there's no registration, it's recommended to send your tip private, in case someone sees your tip and tries to be funny by exchanging it to a coin you don't want before you

https://poorbot.ioHow can someone change our choice of coin if an exchange has been requested? I thought being public or private only hides the tipping process, but any exchange is done in the background. Is this related to how Stake tipping works?
