币界网报道:A $1.6 million crypto purchase on Binance has sparked market manipulation concerns after a trader rapidly bought 658 Bitcoin in 25 minutes, causing a 5% price spike. Blockchain data shows the buyer accumulated over 1,000 BTC ($42 million) across exchanges within hours. While some suspect manipulation, analysts note the purchases could represent legitimate institutional accumulation. The incident highlights ongoing debates about transparency in crypto markets, where large trades can significantly impact prices due to relatively low liquidity compared to traditional markets. Binance has not commented on whether it's investigating the trades.
