I have (no?) idea what if anything BBR has to do with the bytecoin scheme.
I would put it more strongly: Event though it seems probable that CZ involved in cryptonote development, and hence in bytecoin development, there is nothing to link him directly with the pre-mine scam. If CZ was involved early in development but not in the fraud, almost certainly he was at least aware of it, so perhaps the distinction is too fine. If he was involved late, he could have been aware of it, but have no culpability in it. The closeness of the association, however, still would damage the risk profile of BBR in the market's view.
Scenarios in order of increasing investor risk:
1) CZ had nothing to do with BCN, and is not AS.
2) CZ is AS but had nothing to do with BCN.
3) CZ was involved in BCN, but after the pre-mine.
4) CZ was involved in the fraud, but is reformed.
5) CZ was involved in the fraud, and plans to exploit the next suitable opportunity to take money from more honest people.
In the best of these scenarios, BBR still suffers from the risks inherent in centralization of governance. It just gets worse from there on.
, so they have no investor risk. It is implausible that there is any way for CZ to take money from more honest people using Boolberry, so scenario 5 is extremely unlikely. Oligarchy is just as centralized as monarchy.
