I think the crypto fans are currently out of ideas in naming a coin. What they see, and what they find will be used as the name of a coin. This is due to a lack of creativity. I think it's a joke.
There are many names idea they can have if they want to . They are using the name of corona because they know they will be benefited of it in terms of popularity everyone knows about the cotonavirus which is the world problem now.
How will they be benifited ? Ask for donation and the money donate to them will send directly to thier pocket thats thier plan thats why they create this token and use corona name.
