This excuse is becoming common this days kind a hot cake . But keep in mind a good projects doesn;t care about any excuses ,bcz its team work and dedication are high enough 
to go with any obstacle / pandemic  . If a project is good and acceptable for investing people will interesting for such project they'd still success no matter what happen around . For hard economic crisis excuses are not required in reality we need to work hard to overcome these kind of  economic crises. It is unreasonable to make this pandemic an excuse for a failed one we don't belive that bcz crypto and covid-19 are two different things .
