It will not kill the crypto spaces if in case the pandemic covid-19 cannot be completely resolved instead it will give a path for crypto to become useful in the long run as every government will likely to shift to digital payment especially if fiat is not safe anymore. For those government who didn't have a digital payment yet in their country, they will surely use crypto currencies as temporary or even a legal payment option to replace fiat just to avoid the virus.

But the investors will likely to shrink once the pandemic will likely to continue but it cannot kill for sure so the crypto is still very safe as it is a good way to earn a good amount of money/profit especially if your country impose a lock down.
