Police has started investigation and i handed all evidence i got to my lawyer and the police. They are now trying to find out the identity of escrows and nvo team members/ceo/whatever.
Nothing to say much at this point. German police is not the fastest but they search purposefully.

Yeah sure! I work in a web-development company - with the funds worth 500 bitcoins our programmers would finish a fully functional operating system in a year. (Okay, i am a bit sarcastic, but i think with this amount of money you can hire 50 top programmers which would have finished this "little" project in no time)

They banned me from slack - that says everything. I was not rude in the slack channel and i did not insult anyone - i only stated that i´ll file a lawsuit against the nvo team and the escrow.

By the way:
I´ve saved everything posted in that slack channel since December 2017 - so i don´t care that they banned me (to prevent me from collecting evidence maybe?)
i reported to the police yesterday and handed everything (Screenshots, Posts, the Slack Conversations, Bitcoin-Wallet Adresses, the Names of the Bordmembers, the "names" of the escrow) to them and to my lawyer today who made contact to a lawyer which handled such cases before - none of the nvo board members tried to contact me yet to clarify anything and change my mind.

So, let´s see what happens.  
 

Nope.

Yep.

I recieved this message today in the bitcointalk forum:
"
NVO project is one of the largest frauds to take place to date.The "milestones" are only used as a pretext for extracting and misappropriating millions of dollars of investors money in unjust enrichment of a group of scammers who had no intention of finishing this project.This is all an act or drama they are playing out now in order to close in huge profit playing good cop/bad cop between themselves.The argument between the devs is only an excuse/smokescreen so they can walk free and clear with millions of dollars and hand you back a pittance after using your coins for over a year with bitcoin multiplying in price and stealing all the forks from those coins.

It is fraud and theft on a massive scale.
"
I contacted my lawyer who now makes contact to a specialist for economic crime in the eu - i am willing to fill a lawsuit in the European Union against all members of the nvo board and also against the escrow - i don´t know if any of them lives in Europe, but i hope so. The first step is to file charges at the police in Germany, which will be done today. I have a pretty good legal expenses insurance which will pay for the lawyers - i would be even fine with a legal settlement, but i would prefer to see some of these scammers in court.
it´s not even about the money, i "only" invested 2 btc - but i am so pissed about this team, the miscommunication and where all this led to. Nevertheless, i am not very confident that this will head anywhere - but at least i will give it a try.

I think the team only developed the "wallet" for the milestone. The escrow holds still most of the coins - so the escrow is also in possession of the fork money (BCC, BCG, BCD etc.) - they have no right to keep that money.  

I liked the concept too, but this smells all too fishy - the delays, tswrs shilling, the murder story told by ton, the story that imed is a psychopath, the disappear of yanni and so on - that all sounds like a very bad mexican daily soap.

Just fyi.

THEY DID NOT COMPLETE TWO MILESTONES!

The Wallet ist not working at all - it is a mere alpha. They should not get anything for that. So add the funds they get for the second milestone to the refund value. They burned about 1000 BTC for nothing.

3.  Really people need to stop calling it a scam.  I would call it a shitshow but it wasn't a scam. For some reason, people think the money collected was considered an investment.  All funds collected are considered a donation to the team.  The team has no duty to provide details on how the money was spent.  The escrows are the ones asking for a vote by the community to refund the remaining funds.

Nope, this is complete nonsense and bullshit - an ico is not a charity event for donations for the team - it´s a round of financing for a product - so everyone who gave the money to the team is in fact an investor (which you stated in point 2)
