After the implementation of the HBD Stabilizer, $HBD has actually been incredibly stable with variations of 1/100th of a cent. Don't be fooled by what some aggregators display as they are missing liquidity in the internal market as well as DEXs.
Also, @godfish has suggested we, as individual users, can use Hive's internal market to make some gains with arbitrage and help keep the $HBD price stable in the process. win-win. I am not an expert trader, so I don't feel qualifies to make a tutorial about this, but I'll gladly contribute my video production skills to collaborate with someone who can break down these concepts and would like to share this knowledge with the community.
