On February 28th, it was reported that US President Donald Trump will give a speech later on Friday, and market volatility appears to continue to increase. Griffin Ardern, head of options trading and research at crypto finance platform BloFin, said: "Domestic policy in the United States has become volatile, and the White House seems happy to take advantage of this instability. Given the challenges investors face in obtaining accurate forward guidance, many prefer to hold low-volatility assets. Traders need to liquidate positions to reduce exposure to specific assets before moving on to other markets, which explains the decline in almost all asset classes, including cryptocurrencies."
