These past few days, lots of projects' airdrops are using palm print verification...

For small accounts it doesn't matter, but try to use your own for main accounts. If they ever do a second verification, that's when you're really screwed.

Also, from what I've heard, this app scans your palm print and then generates a unique ID based on a specific algorithm that gets stored on their servers for future repeat verifications.

Based on this trend, it looks like future project airdrops will likely use social accounts + palm print ID as a trinity to determine eligibility. For sure some projects will integrate this data to use as a standard for judging Sybil attacks.

Everyone needs to keep their accounts unique...
