On February 28th, the US stock market fell sharply again on Thursday. The three major indexes collectively closed down, the Dow fell 0.43%, the S & P 500 fell 1.59%, and the Nasdaq fell 2.78%. The technology sector led the decline, and the seven giants collectively fell and lost nearly 550 billion dollars in market value. Among them, Nvidia's latest financial performance was "good but not amazing", which caused the stock price to rise 2% from the opening to close and lose more than 8%, and the market value evaporated by more than 270 billion dollars. The crypto market plunged again, led by technology stocks. Bitcoin fell below $80,000, hitting a new low since November 11 last year, a 24-hour drop of 4.7%; Ethereum fell to around $2,100, erasing all gains since August last year; SOL fell below $130, the lowest in five months. At present, from the historical high, Bitcoin has fallen by more than 25%, Ethereum has fallen by more than 45%, SOL has fallen by more than 55%, and a large number of counterfeit products have also fallen to an all-time low in the past two days. Market sentiment continues to be in a state of extreme panic. Although the decline is huge, there is still no sign of stopping the decline.
