40,000 BTC, not 10,000 BTC. Massive regret.
I doubt he feels as much regret as most people think. He’s gotten donations over the years and surely kept some BTC that helped him achieve a little financial jumpstart in life. What most people might not take into account is his side of things. He ran software on his computer for a couple weeks, got some free pizzas, and now he’s a legend that Bitcoiners talk about every year and may forever. Sounds like a great deal to me, not something to regret.
If I was lazslo, I would feel regret or not feel regret about those pizza deals.
I would feel massive regret if I sold all my coins for those pizzas and I did not own any coin after those deals. Like if I only have 10,000
BTC or 40,000
BTC and sold them all for pizzas. Then I only got empty wallet after those deals, I would feel those deals are my big mistake and regret a lot years later when
BTC has very good parabolic price growth.
I would not feel regret if after those deals I still have coins which can help me richer when
BTC made its all time high in 2013, 2017 and 2021. No regret if with only 100
BTC or 1000
BTC after those pizza deals, I still was able to be millionaire or billionaire.
