Historically, whenever you get a free coin, it plummets in value.

Just look at:

-Bcash (bitcoin cash)
-Ethereum classic
-Every single other bitcoin fork
Uni token (its way down in btc and eth value although USD value is up)
-1Inch token

And so on, sure we might get a temporary pump if there is super low supply and a moment of increased buyers, but unless there is incentives to keep buying the token then most people will cash out some or all of their airdrops.
