There is nothing to fear about the market or any possible economic crisis in the future. Cryptocurrencies particularly bitcoin can weather out this kind of crisis and their prices may even go up because investors that affected by the crisis may invest in bitcoin and other virtual currencies insread of stocks or foreign exchange.
Crypto will not be immune on any economic or financial crisis. All coins values will drastically reduce in case of such crisis.
Of course they will. After every crisis people start to pull out their money form the markets and the downward spiral starts. Crypto isn't immune to this.
