as for hbd let me use gpt because it's a lot of writing and I see that it spits out a reasonable result:
Summary of HBD Issues and Blurt Developers' Decision
Main Issues with HBD
Susceptibility to manipulation – Speculators can artificially inflate the price of HBD and then exchange it for HIVE, allowing them to accumulate more tokens and drain the ecosystem.
Lack of stability – Although HBD is intended to be a stablecoin, its price often deviates from $1, undermining its credibility as a payment method.
No real backing – The token is not backed by assets such as gold, dollars, or Bitcoin, making it vulnerable to devaluation during financial crises.
Risk of a downward spiral – During sharp declines in HIVE’s value, HBD conversions may not function effectively, leading to further destabilization of the ecosystem.Why Blurt Developers Abandoned HBD
Lack of control over stability – The Hive system uses algorithmic conversion mechanisms that do not always maintain HBD at $1. Blurt’s developers recognized this as a serious risk.
Protection against market manipulation – By excluding HBD, Blurt prevents large investors from exploiting price fluctuations to accumulate wealth at the expense of regular users.
No need for such a token – Unlike Hive, Blurt opted for a simplified economic model that does not require an algorithmic stablecoin.
Avoiding Hive’s mistakes – Hive has faced ongoing issues with HBD’s stability, so Blurt eliminated this system to ensure a more predictable and sustainable ecosystem.
Final Conclusion
Blurt developers abandoned HBD because it is unstable, vulnerable to manipulation, and lacks real backing. They chose a simpler financial model without an algorithmic stablecoin to create a more reliable and transparent ecosystem.
