Is $25 XLM worth your privacy (identify).
You are linking your identity only to those $25. Nothing else. You dont link it to your salary or. Well you probably already linked that in past. and is mouch bigger figure probably then $25.
$25 is worth different to different people. For some is not worth the time, for others it is worth.
$25 doesn't sound much but multiple times of $25 is a different story. Many people made a fortune from this airdrop of XLM by cheating on KYC. Even if they didn't cheat, then I agree with you that $25 is a decent amount to many people, especially in third world countries, when they care less about their identity over many other financial concerns.
But you dont link you identity to your wealth. You link it just to those $25. If I have 1000 BTC and i apply on that exchange and KYC there, my 1000 BTC wallet was not KYCed. Still no oen knows whose that wallet is. What people will know is that I own $25 of stelar.
