Yeah no, thats crazy. This could work with a electronic implant that is your hardware wallet key. Otherwise hell no.
I was thinking about someone that has like hundreds or thousands of Bitcoin that wish to keep his Bitcoin safe in cold storage but still in reach for many years, as a bet that Bitcoin's market cap will eventually beat other payment processors.
You keep those until its time to retire, then take it out and cash out, live the good live.
And what if the doctor that implanted the chip has connections to some mobsters and tells them about you walking around with million dollars worth under your skin?
What will happen to you then?
Not very safe in my opinion.
Haha, you're funny. If its cold storage it wont be a chip. And there is no way what the "doctor" would know what it is. There is no way you should rely on a chip for storing millions of dollars.
Either its cold storage and its not a chip or its a chip for accessing it often (not cold storage).
