I'm proud to say that I was able to acquire about $100 worth of product from the dark web using only what would turn out to be several hundred thousand dollars in bitcoin, so at least mine are still in circulation
On the flip side, when I was packing up our house, I found some old paper wallets that I assumed were empty (from a time when I was doing some experimentation with various scripts). One of them had about $2k in BTC, that I promptly added to our downpayment on our new house.
It's funny to imagine how much the one "random act of pizza" I contributed multiple BTC that I mined on my Dell Dimension Pentium machine (worth multiple pennies USD then) is worth now.
