There was a technical problem on the US stock exchange. Buffett's Berkshire Hathaway sold 46 shares at $185.1, with a price of $630,000 per share. This person made $85 million for nothing. This was pure speculation based on luck, which was a mistake of placing an ultra-low price and waiting for the market price/automatic stop loss. If the transaction was finally valid, he could brag about this order for the rest of his life.
