Put a few of my Casascius coins up for sale. They have been vaulted and tokenized by 4k.com. They can be purchased via OpenSea and then shipped to you anywhere in the world fully insured. Happy to answer any questions or entertain offers.

Why would you not tokenize a bitcoin coin on the bitcoin blockchain?
