After digging a little bit deeper, I don't buy
this explanation from CZ that he ignorantly thought it was just a standard network upgrade:
Done, unvoted. 1 oversight on my part. Miscommunication/upgrade rubber stamp. 2 @binance have no interest in chain governance. We stay neutral. 3 will continue to support regular upgrades/hard forks.
I'm not familiar with Steem so I can't verify all the blockchain evidence, but this sounds pretty damning:
Early March 2nd, 2020 the exchange Poloniex.com began a process of embezzlement of an unknown number of user accounts funds. The funds, primarily a crypto currency called STEEM were loaded into the Poloniex account, with the amount embezzled equalling roughly 2,283,437.60 STEEM, which was locked away in a manner making it impossible for users to access their funds for trading or withdrawal from the exchange. This was done by locking up the STEEM by converting it into a form called STEEM Power (SP) which can be used to vote on things or gain influence within the STEEM blockchain.
Two other crypto currency exchanges exhibited similar behaviour which included embezzlement of users STEEM currency via means of converting it in STEEM Power as Poloniex did. These exchanges are Binance.com and Huobi.com, both of which received a substantial transfer which I believe a bribe in order to get them on board for this embezzlement scam, which lead to all 3 exchanges using their ill-gotten STEEM Power, derived from embezzling their users STEEM currency to elect their own delegates on the blockchain, essentially taking it over via the custom software they had deployed.
In the attached image(A1) show a transfer from an account called "steemit" which is owned by Justin Sun, the person who also owns Poloniex.com transfering 2,000,000 STEEM to the account "deepcrypto8" which is owned by Binance.com. This is bribe money from the owner of Poloniex Justin Sun given to the owner of Binance.com in order for them to become a part of the scheme to embezzle their users STEEM funds, convert them into STEEM Power and use said STEEM Power to elect their own delegates onto the STEEM blockchain.
In the attached image(A3) you see a 1,000,000 STEEM tranfser to huobi-pro account from an account called misterdelegation which is also owned by Poloniex.com owner Justin Sun. This is another bribe in order to get them on board to embezzle user STEEM funds, convert them into STEEM Power (which cannot be withdrawn by exchange users) and then use them to elect their own delegates.
CZ's claims of ignorance already look like a cop-out. A direct transfer of 2,000,000 STEEM from Justin Sun to Binance adds fuel to the fire.
I'm also concerned about the allegations about locking customer STEEM and converting them to STEEM Power. How does this process work? Did the exchanges have enough STEEM on hand to meet their customer obligations after doing this?
