Lol $50,000 is nothing if you were around in the era of ICO. Airdrops were so rewarding, even the ones that were of meaningless tokens. I remember getting an airdrop of some random token and even forgot about selling off the coins, the token value would then go up to around $4k.
So yes, just like we saw faucets die out, airdrops will also become completely meaningless and a waste of time in the near future. In fact, most of them are already useless.
Airdrops as we knew them died a long time ago, because it was not only the monetary reward you could get with them, at the time the only thing you needed to do to receive an airdrop is to give the address in which you want it to receive it and that was it, now for an airdrop to be given you need to work for months not knowing what will be the specific conditions to receive it, so it is obvious that is not an airdrop anymore and it is just a way of bounty hunting.
