ChainCatcher news, Coinbase's research director David Duong stated that recent claims about the "largest short position in ETH history" are greatly exaggerated.He pointed out that in June, the net inflow of Ethereum spot ETFs reached $1.16 billion, while the short positions of leveraged funds on CME Ethereum futures increased from $466 million in early May to $1.6 billion on June 24, which is consistent with the inflow of ETF funds.Duong explained that this phenomenon is mainly driven by basis trading. Since the basis yield of CME Ethereum futures compared to spot has risen from an average of 6% in February to 8%-9% in May and June, it has attracted more institutions to participate in arbitrage by buying spot and selling futures, which does not indicate a pessimistic outlook on ETH.

ChainCatcher news, Coinbase executive Conor Grogan stated on social media that the "14-year dormant Bitcoin ancient whale transferring $8 billion BTC" yesterday may involve the possibility of private keys being stolen or leaked.Conor discovered that one hour before the large-scale transfer of BTC assets from the whale wallet, one of the wallets conducted a test transaction of Bitcoin Cash (BCH) and immediately transferred out all BCH. Conor believes this behavior pattern is unusual, as other BCH wallets were not utilized, and BCH is generally less monitored by whale tracking services. This could be a discreet way to test the private keys, and he speculated that these wallets are unlikely to be exchange wallets.Conor stated that while this is just speculation, if true, it could be the largest digital asset theft in human history.

ChainCatcher news, Coinbase's product head Dor posted on the X platform stating that this week they handled a fraud case. After choosing to pause transactions and request more information from users regarding the transactions, they decided to deny the transaction and restrict the account due to the inability to contact the account owner, in order to prevent account theft. The goal is to protect users from unauthorized account access and withdrawals, but this has led to frustration for a legitimate user (who must go through the account recovery process).Coinbase is balancing this situation and has already reduced account restrictions by over 80%.

Coinbase CEO Brian Armstrong responded that it is crucial for the platform to reduce account restrictions while ensuring customer safety, and finding the right balance is essential.
