I'm a modern artist, and my work is highly sought after. To date, I have created 10 pieces of art that had a fairly high and stable value--until a break-in occurred and two of the artworks were destroyed by people who don't like art. Now there are only 8 of my masterpieces in the world and their value went up because there's fewer works of art with my name on them. Granted, I have more art in the pipeline, therefore seeing the value of those remaining 8 pieces of art worth less when my new art enters the marketplace.
In a nutshell, if there's 7 million bitcoins, and 1 million are destroyed, doesn't that increase the value of the other 6 million?
That's not what happened... some of those coins (I know for sure Meze Grill in New York) earned them by selling sandwiches.... so the thief came in and stole his hard earned work. He didn't destroy the coins, he just gave a big FU to hard work and stole them... and now is dumping them on the market.
I'd be surprised if the grill continues to accept bitcoins if this is allowed to continue.
