After the crisis of covid-19, many will have to withdraw their assets in BTC
Nope, I don't think that will most likely to happen. Crypto enthusiast knows that there is an important event that's about to come and will possibly initiate a bull run. People are still very optimistic about the effect of block halving and that explains why Bitcoin didn't fall deeper than the $4,000 bottom. While the global economy is down, cryptocurrency didn't seem to be affected by a great number and currently doing well these days.
So, If you're a smart investor, don't withdraw anything until you hit the target.
