One interesting story came up during the article which was that early on in BTC's history, some guy paid 10,000 BTC for a pizza. Betcha he isn't laughing now.
He did not pay his btc for pizza. He gave them to delivery guy. Pizza guy got his fiat money. Delivery guy got his 10K btc which were worthless at that time. If he did not waste this btc for gambling, he is probably laughing now.
