At the end of airdrops their price must skyrocket (at least i'm betting on it)
Blackbytes are not on any exchange and might never be.
That's due to their nature. They can't appear on any explorer or anything, like regular cryptos so you can't know what addresses hold them.
If they are not easy to trade, I wouldn't expect them to rise in value.
They are actually quite easy to trade, if someone is interested. There is an excellent bot who uses smart contracts to do the trades. Here you can see the recent trades:

The only point is that blackbites cannot be traded in usual exchanges. So they should be bought just if you want to own them for future use, not if you want to gamble them.
