If you are interested in how secure is HBD at the moment, this place can give you some info.
Some important parameters from above:
- HBD Marketcap 9.4M (HBD in DHF excluded)
- Debt 2.5% (max allowed 10%)
- HIVE price when haircut starts 0.23$
- Interest for HBD in savings 12%
Probably the most important parameter is the debt level, that now is super low at 2.5%, indicating a great stability for HBD.
The max allowed debt is 10%, after which the value of 1$ HBD is no longer guaranteed by the blockchain. In the next hardfork this debt level should increase to 30% providing more security for HBD investors.
The HIVE price when the haircut starts is another interesting parameter, although this is dependent from the other metrics like HBD supply, debt, and can change in time. At the moment, the 9.5M HBD is safe until HIVE hits 0.23 :)
