Whether or not the current airdrops are related to covid19, they all are far from being legit. From my point of view, as I have been watching drops posted on social media for more than an year, every airdrop either has enough red flags to be called a scam or provides not enough information for proper investigation, which also might mean it is a scam. All airdrops are remain the same, the only thing that changes is what is currently overhyped, on which the scam airdrop can be based at the moment. No matter how attractive airdrop looks, it is always better to avoid participating in it.
not all airdrop named COVID19 is a scam, I found a legit corona coin airdop
