The main flaws I reference are:
- Environmental damage due to vast power consumption
- Financial harm to individual investors due to extreme instability and lack of regulation

- Helping organised crime organisations due to untraceable finances

Suggestions for additional flaws of similar importance are welcome.

To resolve YES, it must be shown that all listed flaws have either had their impact reduced >90%, or to within 10% of that by conventional currencies, whichever happens first.
