Amid the recent downturn in the crypto market, something unexpected happened again. Whales and institutions once again brought up the Mentougou black swan event, causing Bitcoin to fall to a low of $58,378. Coincidentally, there have been reports of continuous selling of Bitcoin in Germany recently, casting an endless shadow on the market. Regarding yesterday's strong rebound in Bitcoin and altcoins, many people in the market believed that it was whales and institutions who lured more people to sell, but some analysts believed that altcoins were almost halved. The season of altcoins has arrived, and we will wait and see the different views on the market.
