Binance Hacker Consolidates Stolen Bitcoin to Seven Addresses

The hacker(s) who performed a large-scale security breach on Binance, the world’s largest crypto exchange in terms of trading volume, have now transferred the 7,070 Bitcoin (BTC) they stole to only seven addresses.

Hackers Also Obtained Users' 2-Factor Authentication Codes And API Tokens

On Tuesday (May 7th, 2019), Binance suffered a damaging hack in which hackers managed to not only steal bitcoin’s valued at over $40 million, but they also reportedly gained access to users’ 2-factor authentication codes and API tokens.

According to a report published by The Block on May 9th, 2019, the stolen Bitcoin was transferred from Binance’s hot wallet on Tuesday via a single transaction - which consisted of 44 outputs. Notably, 21 of these were Segwit, of Bech32, crypto addresses and 99.97% of the funds have been moved to them.

Moreover, the hacker(s) have now consolidated the stolen bitcoins from the 44 crypto addresses to only seven addresses. At present, six of these addresses hold 1,060.6 BTC and one address is holding 707.1 BTC.

The addresses reportedly containing the stolen BTC are as follows:

  1. bc1q3a5hd36jrqeseqa27nm40srkgxy8lk0v0tpjtp (Bech32 address holding 707.1 BTC)
  2. bc1q2rdpyt8ed9pm56u9t0zjf94zrdu6gufa47pf62 (Bech32 address holding 1,060.6 BTC)
  3. bc1qx3628eh9tdnm0uzculu8k6r2ywfkc5zns2hp0k (Bech32 address holding 1,060.6 BTC)
  4. bc1qnf2ja3ffqzc3hskanjse6p8zag52fm6jgmmg9u (Bech32 address holding 1,060.6 BTC)
  5. bc1qw7g5uxxl750t0h2fh9xajwuxp4qt634yh3vg5q (Bech32 address holding 1,060.6 BTC)
  6. 16SMGihY94H8UjRcxwsLnDtxRt7cRLkvoC (P2PKH address holding 1,060.6 BTC)
  7. 1MNwMURYw1LkPnnpda2DQkkUsXXeKL9pmR (P2PKH address holding 1,060.6 BTC)

Before The Block confirmed the list of addresses above (which currently contain the stolen funds), Confirm, a London-based anti-money laundering and counter-terrorism (AML/CTF) firm had revealed via Twitter that it found that 1,227 BTC was initially moved from the Binance hot wallet to two other crypto addresses, one of which contained 520 BTC and the other held 707 BTC.

Binance CEO Considers Chain Reorg After Hack

Following the 7,070 bitcoin hack, Binance CEO Changpeng Zhao (or “CZ”) had initially proposed the idea of performing a chain reorg - which could reverse the set of transactions made by the hacker(s). This, CZ had first said, would help recover the funds and serve as “revenge” against the malicious actors.

However, the crypto entrepreneur decided not to attempt a chain reorg after consulting with various experts in the cryptoasset industry.

Bitfinex Wants to Offer 100x Leverage For Crypto Derivatives Trading

  • Bitfinex will offer 100x leverage trading for cryptocurrency derivatives
  • According to the exchange's CTO, the hedging product is "ready for prime time"

Cryptocurrency exchange Bitfinex revealed it wants to offer derivatives products with up to 100x leverage for cryptocurrency traders. 

Hedging On Cryptocurrency Derivatives

Chief Technology Officer Paolo Ardoino told The Block on June 25 that the cryptocurrency exchange was ready to ship a 100x leverage product for certain users. According to the post, the project has been under development for some time and is “now ready for prime time.” 

The product was referenced in last month’s whitepaper published by Bitfinex for its $1 billion private token sale of LEO, stating

“Qualified Bitfinex account holders will be able to trade a new hedging product through a derivatives wallet.”

The whitepaper originally claimed that the new hedging mechanism would be released by the end of June, a timetable that fits with Ardoino’s “ready for prime time” statement. 

Ardoino confirmed that only “verified” customers will be allowed access to the product, given the risks involved in such highly leveraged trades. 

The CTO also took to Twitter to quell user concerns over Bitfinex’s existing 3.3x margin trading. Ardoino explained 100x leverage will be “optional,” and that their current leveraged trading products will be unaffected by the release. 

Big Risk, Big Reward

Bitfinex is looking to compete with rival exchange BitMEX, who already offers 100x leverage through its bitcoin perpetual swap contract. However, Bitfinex claims its product is designed as a legitimate hedging tool for clients, rather than a gambling mechanism. 

Max Boonen, CEO of trading firm B2C2, believes the product will only appeal to retail hedgers, as large investors will shy away from the risks involved in 100x trading. 

According to Boonen, 

“There’s nothing wrong inherently about 100x. But as a commercial hedger you want lower leverage margin. The larger investor wouldn’t want to take the risk of 100X, typically. They don’t want to go balls to the wall.”

The cryptocurrency derivatives market has been heating up. Last week bitcoin-bull Mike Novogratz’s Galaxy Digital announced plans to offer cryptocurrency options contracts.

Binance has also reportedly been exploring futures trading. On June 24, Binance CEO Changpeng Zhao tweeted the exchange had executed its first margin liquidation for a BTC short.
