I think the best option be will be keeping some money in cryptocurrencies because this way globally the countries would be able to support each other since every single investment counts .. this way we will be able to go though global crisis easily.. even if the country's economy goes down you could still count on the bitcoins and all..
This way we could count on someone other than the governments..
The crisis will come (I mean worse than now). However, the crisis can be delayed if governments find where to get more money to cover the debt burden due to it. Cryptocurrencies can become such a tool. Look at FB, which launches the Libra cryptocurrency with the goal of making even more money from people and all these threats from regulators are nothing more than a statement for the general public.
In fact, people will give their cash to Facebook, and they will use these funds to buy short-term bonds of the US government debt and thereby support their economy.
