A diamond for cryptocurrency

Sometimes, just sometimes, I start thinking about diamonds. As I mentioned in this post from 2020, I think they make for great MacGuffins in crime fiction. Precious gemstones is one of these tropes that in my opinion never gets old. So yes, sometimesI think of diamonds and I then read about diamonds. So I thus recently learned that Sotheby's will accept for the first time cryptocurrency for the auction in Hong Kong of a 101.38-carat diamond that could be worth $15 millions. Now, I don't know much about cryptocurrency, but I don't really trust it. I read this and it was like Sotheby's is selling a $15 millions rock and they'll accept Monopoly money. Something of the romanticism attached to diamonds get lost. Nevertheless, I can imagine the potential for a solid crime story, especially given the volatile (in my view) aspect of cryptocurrency and the ever darker aspect of diamonds, the embodiment in stone of human greed and the cause of so many crimes and wars. It's easy to imagine something going wrong in that auction.
