Yes, you're right. On the other hand, we currently have a 30% debt ratio limit set, which makes HBD "safe" for a while - we're currently at 7%. As long as the HBD Stabilizer works and Hive keeps over say $ 0.15, I'd personaly consider HBD in Savings as a great option. Having a different opinion is fine with me, obviously, that is a subjective matter :)
I just don't have and have never had anything in Savings because I dispute the whole concept of HBD insterest and taking advantage would be hypocritical. Also, I care about Hive :) That's also why I am against the interest :)
