BitMEX co-founder Arthur Hayes sold $8.32 million worth of Ether (ETH) last week, citing concerns over the market slump.

However, Hayes seems to have changed direction, as just a few days later, with prices soaring to $4,200, he bought back $10.5 million worth of Ether.

The quick repurchase suggests that Hayes may anticipate a rise in Ether again, which contradicts his previous predictions of a market slump.
