I'm curious about how many Bitcoins are effectively dead (i.e., lost private keys, owner dies, etc.). I imagine it is more than 10% of all coins. It will happen less and less, but with so many people who mined when they were worth next to nothing, I would think most of the early Bitcoins died. What do you think?
3-8% i think is lost, 10% so much. Most lost was on mtgox, by freezing accounts. Look on the fiats, people always lost that, more than btc. So you can to mind about that.
