It's crypto and anything can be done without even meet the team face to face. There was a lot of crypto developers were doing teleconference to did a meeting or something else. The development will always still continue but just hope this pandemic will not be so long. It's really hurt to see so many countries are dying right now.
Since crypto is in internet so it's fully support to do through online conference, I think even for investors it doesn't matter as long as development keep going. The important thing is that the product of a project which will be displayed accordance with the promised details and on time. It won't be a problem, the problem is only the scammers.
