Most people get the Bitcoin pizza thing wrong. What it did was set the first proper price of Bitcoin. Before that, it was basically a worthless digital trinket. So Lazlo, the guy who spent the Bitcoin, will go down in the Bitcoin history books as a very significant player, doing a very significant event. So yes, right now it looks stupid, but someone had to be the first to use Bitcoin, someone had to swap it for a physical good, someone had to put a proper value on it.
Nah, she wouldn't have kept them. Few have any of the original Bitcoin left from the old days. And that makes sense, because you don't buy something at a few $ or cents and go through 4-5 major bear markets without taking advantage of the upmoves. Put it in stock terms. If you bought a big postion in XYZ at $1 and it went to $100 or $500, would you say, hell, I'm waiting for $10k+ or would you take much of your 100x or 200/300x and crystalise a damn fortune?
I would call this a barter not a currency trade Do you remember this guy https://en.wikipedia.org/wiki/J._S._G._Boggs Boggs began drawing currency in 1984, when a Chicago waitress accepted a drawing of a one-dollar bill in payment for his restaurant tab.[3][4] His drawings of currency, depicting only a single side of the note,[5] came to be known as "Boggs notes".[6] Boggs notes were both art objects and part of a performance.[7] Boggs would exchange the notes only for their face value: when he drew a $100 bill, he exchanged it for $100 worth of goods. He then sold any change he received, the receipt, and sometimes the goods he purchased as his "artwork", typically to art dealers and collectors.[8] Boggs would tell a collector where he spent the note and the details of the transaction, but he did not sell the notes into the art market directly.[9] The buyer would then track down the person in possession of the note in order to purchase it.[8] Boggs noted that after the initial transaction the notes would be resold for much more than their face value,[10] with one Boggs note reportedly being resold for $420,000
