I don't blame it on covid but yes covid coul prove to be a like fuel to this fire. If there is a big famine we will be having a crash just like 1929 great depression which most of the economist have actually warned about. But I don't think this sort of famine would harm the whole world today most of the countries have tried to become agri self sufficient there are a very few major countries which are entirely dependent on other countries for staple diet.
I don't want to sound rude or anyway want to sound negative but this sort of thing is actually good for BTC as it will realy show peolle how worthless can fiat be. Moreover we have seen btc prices shooting up in times of anarchy so this may be a case.
