How did >3,094 BTC turn into 1169 BTC without this being a scam?  

~60% of the funds have been disbursed to the team according to milestones and the remaining ~40% (probably more due to forks) are likely to be refunded pending a vote, which is in progress: https://nvo.party/

Some folks here seem to use a definition of a scam as "anything less than 100%" but the initial 30% distribution was set in stone basically (end if ICO / start of development) and the other 30% seems to be quite straightforward too (availability of beta wallet software IIRC) so there isn't much room for a scam unless the escrow actually runs at takes some or all of the 40% with them.

Where did the 10-78 missing BTC from the BCH sale go?  Is there something quoted above that is not true?
