A whale portfolio linked to former BitForex CEO Garrett Jin has opened approximately $900 million in long positions on major cryptocurrencies, according to on-chain analytics platform Arkham Intelligence.

The positions include $733 million in Ethereum, with additional exposure in Bitcoin and Solana through leveraged derivatives on Hyperliquid.

This marks the trader's return to aggressive positioning three months after allegedly profiting from the market crash in October 2025.

What happened

Arkham reported on Friday that the wallet increased its existing long position on Ethereum by $66.2 million, bringing the total combined exposure on ETH, BTC, and SOL to over $900 million.

The same wallet address had generated an estimated profit between $190 and $200 million by shorting Bitcoin and Ethereum less than an hour before President Donald Trump announced a 100% tariff on China on October 10, 2025.

This perfectly synchronized short triggered wide-ranging insider trading accusations, which Jin categorically denied on social media.

'I have no ties to the Trump family,' Jin said in October, adding that the wallet belonged to a client.

On-chain investigators initially linked the wallet to Jin through Ethereum Name Service data showing connections between the addresses 'ereignis.eth' and 'garrettjin.eth'.

Why this matters

The new long positions represent a dramatic reversal from the bearish bet in October, suggesting strong conviction that the current market momentum will hold despite macroeconomic headwinds.

Jin's October trades occurred during the largest single-day liquidation in crypto history, with $19.13 billion wiped out globally as Bitcoin briefly fell below $102,000.

This timing – less than 60 minutes before Trump announced the tariffs – triggered a close examination, particularly from prominent figures such as Binance co-founder Changpeng Zhao, who shared the accusations with his 10 million followers.

However, leading on-chain investigator ZachXBT suggested that the trades may have been executed by 'a friend of Jin' rather than by Jin himself.

BitForex, which Jin led from 2017 to 2020, collapsed in 2024 after losing $57 million in hot wallets amid allegations of fraud from Hong Kong regulators.

The current positions of $900 million utilize high leverage on Hyperliquid, creating significant liquidation risk if Bitcoin and Ethereum reverse their recent gains.
