As for what's going to happen to bitcoin (and the altcoin market, too) after COVID-19, I get a queasy feeling in my stomach when I think about what'll happen when interest rates start to rise or if unemployment starts to go up, in addition to the inflation of the USD that I've been expecting for years now. In other words, if the economy in general gets fucked up bitcoin and all of its little duckling alts are going to suffer. Massively.
The economy has already suffered as a result of the pandemic and still continues to suffer with some signs of recovery, because governments and the population have already come to terms with the ongoing pandemic and have found ways to continue economic activity. Therefore, after the end of COVID 19, it seems that we should expect an increase in economic activity, but it is not fully clear how this will correlate with the inflated stock market and whether this will lead to another crisis. In theory, in the subsequent crisis, bitcoin will have to behave as a protective asset, but not immediately and not constantly, last year's events about the exchange rate of bitcoin clearly hint at this.
