Still on the Bitcoin Pizza day symbolic day we have 4 days left to the main day. Bitcoin Pizza Day is officially celebrated annually on May 22
Sad to know that the people he bought the pizza from did not hold on to the Bitcoin. Instead, the coins were likely exchanged or spent shortly after the transaction was made.

No, you can't blame them for not holding the Bitcoin as they didn't know what the future brings, and most of us here as well who might have known Bitcoin before but didn't invest because we think it's a scam.

But what's important is that Laszlo did something that really help boost Bitcoin's image in the early days.

Doesn't matter if it is 4000 or 10000. He was one of the pioneers and so with that, every year we celebrate that day in honor of the man. He even did replicate this with LN if I remember it correctly. So we should be thanking Laszlo Hanyecz for what he did.

I just guessed, at the beginning he must have regretted it, because humans must have regrets, especially after seeing Bitcoin currently becoming one of the legends in the Cryptocurrency world, even with a very fantastic price. But slowly he will definitely not regret it because he is the one who commemorates Bitcoin Pizza Day, and right this month we will commemorate that day on this forum Bitcoin Pizza Day Contest and this has become a habit every May.

On the one hand, maybe he slowly doesn't want to regret it anymore because like you said. He bought it using bitcoin because at that time bitcoin was not valuable, even because buying pizza with bitcoin was the first transaction if I'm not mistaken in buying and selling, maybe if he didn't buy pizza using bitcoin, bitcoin wouldn't be like it is now. So actually he didn't lose anything, besides that bitcoin at that time had no guarantee at all. Bitcoin was still very small at that time and could fail, maybe if we were in his position at that time we would do the same thing.

Laszlo had either invented or innovated on some abilities to greatly increase his mining power by implementing GPU rather than CPU mining, and so at that time, his mining equipment was winning a disproportionate quantity of the bitcoin mined blocks, and so if he found 200 blocks, then he would be rewarded 10k bitcoin (50 BTC per block), and 144 blocks are mined per day, so Laszlo could have had found 200 blocks in a couple of days or maybe within a week of mining.  So the rumor that Lazlo may have bought pizza several times for 10k bitcoin each time, is not unreasonable that he might have had ended up spending 40k bitcoin or perhaps even more for various pizza transactions since it seems that he had several transactions in which he bought pizzas..

You must like to live in fantasylandia.

When it comes to the past, I personally prefer to analyze what happened and try to figure out what happened and to get a good reading on what happened perhaps why it happened, and there can even be various versions in regards to what happened, what is the significance of what happened, where we are right now..which is based on how we got here, and how we got here might also help to inform us where we might be going.

When it comes to the future, we can have a large number of possible scenarios about various scenarios that might be possible, and some of the scenarios have higher probabilities than others, and perhaps we might have 9 or more scenarios with varying odds that might range between 37% for the higher end and 0.5% for the lower end, and so then maybe the higher end scenarios would be what we expect to be most likely to happen, even though historically sometimes lower end scenarios end up playing out and then once they play out, they affect the future possibilities based on what actually happened rather than what might have had happened, and sure yet they happen, they are somewhat locked in, even though we still might argue about what exactly happened and try to understand its significance. 

There could be some ways in which exploring alternative historical perspectives that we might be able to gain a better perspective in regards to where we are at and where we might be going, even though I still tend to not get too excited regarding the discussion of hypotheticals that did not end up happening, since the are likely less relevant in terms of figuring out where we are at, how we got here and where we might be going.

Sometimes we might agree on a lot of the facts of where we are at and how we got here, yet we might have differing perspectives and opinions in regards to where we might be going - which surely investing in bitcoin can have some of these differing scenario elements, and we might not even need to be correct about the specifics of where we are going as long as we get it right directionally, and so for example, we likely are better off to invest into bitcoin rather than not to invest into bitcoin, even though it may well be that 99% of the world's population is either not at all invested in bitcoin or they are way under invested into bitcoin.

Few people know the history of bitcoin's creation, but even those who have never bought bitcoin themselves know that Laszlo bought 2 pizzas for 10000 BTC. And the fact that he has gone down in history forever is confirmed by the fact that every year a holiday is celebrated, which he initiated with his purchase.

It doesnt matter whether 10k or 40k, on which the main thing on here that he's the one do make out that first real world transaction on which this is indeed that could be put up on history. Its understandable that there are tons of people who do make out some computation on how much it is worth now with the current price specially on the new ATH on which its on $1B as far as i remember or seen recently. For sure Laszlo do make out that regret for the rest of his life but actually it could be patched up that he would be just simply thinking that he did make a history that isnt something that could be forgotten. Its none of our business on how much he had spent, if ever that he had 40k on that time then for sure he had still some coins on his wallet up to now that its not been known in the public. Right?

I would think that many of the earliest of bitcoin adopters who were either mining or even if they were purchasing (or exchanging) what seems to be a lot of bitcoin, such as thousands of BTC for relatively small dollar values (or dollar value items), then we should imagine that many of those earliest of adopters would have had enough foresight to have had hung onto at least a few hundred coins - yet surely we have many examples of  many earlier adopters who sold way too many BTC too soon, so we know that such sales of too many coins too soon does end up happening with some people.  It is like they cannot help themselves to want to consume.

It's really difficult to know Laszlo's holding back of some coins based on the information that we know about him, and surely folks like to consider that he has regrets, yet even if he held back several hundred coins and then just spent those slowly over the years, it would be difficult to consider that he would necessarily have had put himself into a position of spending too many bitcoin too soon.

It is a bit ridiculous to look at the 10k bitcoin and proclaim that today they would be worth more than $1 billion, since even though that is true, guys do not necessarily need to become billionaires in order to be quite content with their standard of living.  Many of us may well realize that currently having at least 16.857 BTC is enough to figure out ways to have a sustainable (and perpetual) income of $80k per year, even accounting for giving oneself a 5% to 10% raise each year... so the difference between 10,000 bitcoin and 16.857 BTC is quite a lot, and there surely could have been and should have been that many of the earliest of adopters had figured out ways not to sell too many of their coins too soon.
