Ethical and moral concerns aside, CoronaToken was an interesting concept, but as with many crypto projects, run so badly that it was destined to fail.
Here's what happened
Centralization.
That's it, that's the reason for this:
Hello CoronaCoin community,
Our head dev sold the RedCross donation wallet and left the project. The team decided to continue on without him and created a new $nCoV CoronaCoin contract: 0xb80112E516DAbcaC6Ab4665f1BD650996403156C

And it shows again that blockchain does not automagically mean decentralization. This whole project was run by one person with master key access.
Anyways, I think there is a special place in hell for people running scams using the charity cloak...
