interesting.
Reminds me of that vial of DNA with 1 BTC encrypted in it given out during a World Economics conference in 2016. (if I remember correctly)

Nobody ever claimed it before the expiration in december 2017 (I only discovered it q couple of dqys before the deadline, or I'd have tried to convinced someone in the Uni with access to a sequencer to give it a go with me)

Reading the post title I thought someone had literally put it in their DNA XD
