Blockchain technologies and about 700 different crypto-currencies with its prominent opponent Bitcoin were joined a year ago by Etherum. We investigate a new case of binary options and etherum fraud.

Who did run an Etherum investigation already?

DFC! Please PM me only.

Ok, Ethereum -) I am not perfect.

I guess I can post publicly that the spelling is Ethereum.

Also it is not (or not only) a crypto-currency like Bitcoin.

Ethereum is "a platform" (whatever it means) and the currency on that platform is Ether

Ethereum is a complex issue. Did PM you a cryptographic analysis dated June '17 which I co-authored.

Investigation

https://www.sec.gov/litigation/investreport/34-81207.pdf

Violation Sec 5

Report of Investigation Pursuant to Section 21(a) of the Securities Exchange Act of 1934 The DAO (Decentralized Autonomous Organization)

From April 30, 2016 through May 28, 2016, The DAO offered and sold approximately 1.15 billion DAO Tokens in exchange for a total of approximately 12 million Ether (“ETH”), a virtual currency used on the Ethereum Blockchain. As of the time the offering closed, the total ETH raised by The DAO was valued in U.S. Dollars (“USD”) at approximately $150 million.

Ethereum, developed by the Ethereum Foundation, a Swiss nonprofit organization, is a decentralized platform that runs smart contracts on a blockchain known as the Ethereum Blockchain

Why was it not possible to catch the thief of 2016 DAO hacking and theft? Ethereum claims to be ledger of all historic transactions, what piece of evidence was missing?

A future theft will therefore be sucessfull and not 'catched' also, right?

As FBI was involved, who can share insights for the good to learn (oppose RolfGutmann's request to PM)?

Well, not that IF it was involved anyone would know anything about it (or be allowed to talk about it), but point is that there is no record of any FBI involvement.

All the bloomberg article says is that a few guys involved with the DAO talked with some FBI officials and shared with them some of their own info, but there is no evidence of an actual investigation.

It is also to be seen if the "theft" took place, in the sense that it is not clear at all if an actual "crime" took place, there are arguments in favour of it being an actual ""theft" and thus an actual "crime", but there are also arguments about the particular "smart contract" being only highly unethical.
http//www.ibtimes.co.uk/legal-experts-examine-dao-attack-ethereum-fork-1566318

As seen from the outside, if you decide to create something to "disrupt" the "traditional" means used in the economy where the "novelty" (and "selling point") is that "the contract is Law" and that it is self-regulating and independent from *anything* creating diffused inherent self-trust, and expressly conceived to be outside (and above) the Law of any country, it seems a bit difficult to be able to ask for remedies to the Law (or to its enforcement agencies).

On the other hand, in the (allegedly) words of the (alleged) DAO hacker
https://pastebin.com/CcGUBgDG
the situation is reversed, according to him/her, while the "hack" did not infringe any Law, Law can be used (by him/her) to "get the money".

The whole thing seems however a lot like "cheating legally" in a Las Vegas Casino, the FBI won't do anything if you manage to count cards at the blackjack table and win a lot of money.

Got response from Bitcoinsuisse AG about the '16 theft of Ethereum (not BTC)

Hello,

My name is x.y. (removed by me). I am a % (removed by me) with BitcoinSuisse and coincidentally I have also been affected by the DAO hack.

From what I know, we have little information about what happened later. We have been occupied with the work.

Last thing I heard, the attacker went on to exchange coins using Shapeshift and other services, that don't require KYC/AML documents.

It is possible to see the transaction chain but not necessary get any identity behind that.
