Okay, but "buying at 97 cents" means selling Hive after it just crashed 20%.
That isn't buying low; it's selling high.
So the bot needs access to another stable-coin like USDT that has a better peg.

So the bot needs to be able to:

• see the opportunity
• sell USDT reserves into Hive
• transfer the Hive on-chain
• sell the Hive into HBD
• be able to do the opposite when the peg is higher than $1
  • or at least trade back into USDT when the $1 peg is returned

This is a lot of steps and requires API access to the exchange holding the USDT.
Many things can go wrong.
