Why not, crypto currencies may be able to withstand the upcoming crisis as long as government permits the use of it in such harsh conditions. For now we dont know whether this is possible or not because on the practical front crypto currencies are already banned in many countries and most of the countries are using it but they have not approved it as legal tender. Obviously if thats the case then there is no way that it will even help out the economic situation in proper ways. For it to accomodate those problems, it will need to be regulated first. And how will it help? Well it may just become the store value for it and thus unlike gold and silver may become point of storage for the valuable stuff.
