Everyone who transferred large BitCoins in the beginning (100-1,000) to buy items and 'pizza' are kicking themselves in the ass right now.
Yes, it is funny / desperate to think that someone have paid 10.000btc for pizza... I was just today thinking about that... however, actually better not to think so. Value was much different than now and very early times... somehow we´re now still at very early stage, so make sure you think how to use. I think better to save btc and just wait. Might be jackpot or just nice ride!
