What is happening with the new version of it is only an attempt to silence public opinion and to make them be patient with those who lost their savings because of Luna, including the trading platforms themselves that must list the new currency in the hope of recovering as much money as possible which They lost by the Luna collapse.
The new version is the other way of the developer to milk the project aside from what you stated. It is obvious from increasing daily emissions to forking the original chain of Luna. The airdrop is just some strategy to shut the complaint up while abandoning the holders of the old chain supporters.
Even the new luna that was created in order to make the veteran holders feels reimbursed was such a massive failure, doesn't mean it gonna makes everyone hesitant in investing in major coins instead, the brand luna already being judged as really bad and I doubt the new luna gonna survives.
Instead most of the people gonna sticks with ETH and bitcoin
I agree the airdrop is to make old holders feel that they are being reimbursed but the result was really a joke. They are giving old holders a token that is made out of some code with unknown value in exchange for their huge money losses.
