Justin Sun, founder of the Tron network, has applied to unlock 52,905 ETH from Lido Finance, raising concerns about a potential sell-off as Ethereum approaches the $4,000 mark. This withdrawal is part of a larger stash of 392,474 ETH he acquired earlier this year, realizing a profit of approximately $349 million. Additionally, Sun has been active in selling other assets, including moving 198,380 EIGEN to HTX, further indicating his profit-taking strategy amidst the recent bullish momentum in the crypto market.
