I remember that four years ago, the halving of bitcoin brought not only anticipation, but also a sudden crash that caused 90% of investors to lose money overnight. Recall that on March 8, 2020, Ethereum suddenly fell from $250 to $210, a drop of 17%, and Bitcoin also fell from $9,200 to $8,300, a drop of 10%. The market, which originally looked like it would rebound, suddenly changed its face, and everyone panicked. The next day, the U.S. stock market announced a circuit breaker, and the market fell sharply again. Ethereum and Bitcoin continue to slide, and panic spreads. After two days of consecutive declines, although many people have lost, they are still optimistic that the worst is over, and some people have even started to go long again. But by March 12, everything had changed, especially Ethereum, which plummeted from a high of $1,500 to $150. I couldn't hold back either, and I threw myself all into it, trying to seize this opportunity. Almost everyone thinks it's time to go long, and those of us in the group of bears are starting to want to buy the bottom. That same night, because of the panic caused by the epidemic, the US stock market broke again, and the prices of Ethereum and Bitcoin plummeted. At that moment, I thought that the currency circle was coming to an end, and there was no hope for the entire industry and the entire circle. All of them lost a lot of money, and no margin could stop this decline. But just when I thought it was over, a lot of people started buying bottoms again, and there were people trying their best to continue struggling in this market. You think that's the end of it? After a brief rebound, the prices of Ethereum and Bitcoin were hit harder, and the prices were directly hit lower. The decline of altcoins is even more incredible, falling dozens of times. The needles are endless, and they are miserable. All this tells us that in the currency circle, the only thing that can be determined is uncertainty.
