Honestly speaking, I wasn't aware that airdrops are still live in the crypto ecosystem. Just by checking the bounties sub-board in bitcointalk, the phenomena is almost dead since two years at least after the wave of apps lunching in telegram offering free tokens such as $Dogs and $Cats.
Airdrops haven' been profitable since 2017 ICO trends, except for few airdrops lunched by already established projects like Uniswap airdrop that has been almost the most profitable one. However for all the other airdrops, all of them are either scam projects are failed coins that are starting without a budget and just aim to get some volume to reach trading in exchange platforms.
$DOGS, $CATS does not have an ecosystem, more like memecoin.
Airdrops still exist, new altcoin projects continue to emerge with the advantages of the ecosystem they offer, including the most AI agents we know, of course they follow the market trends that are currently hype. --- You know in the end fail.
The best Airdrop is in 2021, the easiest is ARB [Arbitrum] and many more, because now the trend has decreased due to the bearish market, it is no longer feasible to work on airdrop now.
