I wonder how would I feel if I am on his shoes, and realized that my two pizzas worth a million dollars now. Haha. I hope I won't commit suicide.
If I am the one who bought that pizza, I would be really happy today since because of that transaction, Bitcoin became advertised in the way of buying Pizza. The price might not be affected that much by that transaction, it just shows how people use Bitcoin. If I will be wondering, that will be the people who recieved that 10,000 Bitcoins, did he sold it immediately? Or did he saved it and sold it last December?
