During an economic crisis, BTC's performance is not stable, its price will fluctuate greatly, and there may even be a liquidity crisis. For example, in March 2020, due to the circuit breakers of the three major US stock indexes, the Bitcoin market collapsed and prices fell sharply. However, after the fourth circuit breaker of the US stock market, Bitcoin did not fall again, showing signs of stabilization. In addition, the importance of BTC is also reflected in the crisis. Only BTC, which is backed by computing power, can recognize only private keys and not people, ensuring the ownership of assets.
