NFTs require arbitrary data storage, which not all blockchains support (or are prohibitively expensive).

You cant remove pocket and telemetry without recompiling. That’s why its not just a config file.

Essentially it’s a giveaway/handout/distribution to people who fulfill some criteria. There was one coin that gave away significant amounts (>1k USD) to early users and since then it has become kinda popular. Because who would turn down something free?!

Except its not free. For starters, you’d usually have to pay significant network fees to claim the airdrop, and second the money has to come from somewhere. It’s the same with government printing money and distributing some to the people, in the end we all pay for it with inflation. So yeah, pretty scammy overall.
