many people have already answered this question in this thread, I just want to add something that I noticed that nobody spoke. Well, since I am on the forum I see most people talking about Hold, this means that most people are looking at cryptocurrencies as a way to make a profit. it is clear that for most people in the crypto world, cryptocurrencies are investment and not currency. if you look at things from that point, then people will prefer to use Fiat to buy food and when the coronavirus situation is controlled they will think about investments.
