I can't promise you that bitcoin will sustain your needs during this pandemic,so NO you can't rely on bitcoin, since it is a very speculative investment I can't give a 100% guarantee, we should just thank our lucky stars that we are able to work and earn some money in the crypto world, but crypto alone can't save us, so we still need everything to go back to normal.
PS: bitcoin can not prevent a country's economy from crashing, its not a "magical asset" Lol.
Bitcoin is a great tool and in the case of a massive financial crisis it will be an asset worth holding but as you say it is not a magical tool, one of the things many of those that predict such crisis never say is that under those circumstances there will be massive chaos and crime happening on the streets and even if you were smart enough to hold bitcoin before the crisis that does not change the horrible conditions we will have to live through or that your coins can be stolen the old fashioned way.
