Arthur Hayes, BitMEX co-founder and Bitcoin billionaire, has bought back Ethereum (ETH) at a higher price just a week after selling a significant amount. On Twitter, he announced, “I pinky swear, I’ll never take profit again.”
An Interesting Turn from Selling to Buying
Onchain data shows Hayes sold 2,373 Ether, worth about $8.32 million, when the token was trading near $3,507. This sale locked in profits before Ethereum’s recent rally.
However, last Saturday, Hayes moved out $10.5 million in USDC across multiple transactions to buy back ETH at prices above $4,150 — significantly higher than his previous exit point.
He tweeted, “Had to buy it all back, do you forgive me @fundstrat?” tagging Tom Lee, co-founder and head of research at Fundstrat. Hayes added, “I pinky swear, I’ll never take profit again.”

Hayes Issues Crypto Market Warning
As CIO of Maelstrom Fund, Hayes warned last week that mounting macroeconomic pressures could pull Bitcoin back toward $100,000.
Citing renewed tariff fears following weak July Non-Farm Payrolls showing only 73,000 new US jobs, Hayes noted that sluggish credit growth in major economies could weigh on nominal GDP and push Bitcoin and Ethereum lower toward $100,000 and $3,000, respectively.
In anticipation, Hayes sold over $13 million worth of crypto, including $8.32 million in ETH, $4.62 million in Ethena, and $414,700 in Pepe tokens.
Institutions Accumulate $4.17 Billion in ETH
Since July 10, unknown whales and institutions have accumulated approximately 1.035 million ETH — valued around $4.17 billion — through exchanges and institutional trading platforms, according to data gathered by EmberCN.
This buying surge coincided with Ethereum’s strong price rally, climbing from $2,600 to $4,000 within the month — a 45% increase.
EmberCN noted that most of the ETH held by these addresses likely belongs to institutions or US public companies building ETH reserves. This excludes publicly known entities like SBET. The average acquisition price for these holdings is estimated at roughly $3,546.
