When I read about this guy I kept on laughing lol. It was so hilarious like what could have caused him to sell his 10000

Hmm. Hunger and he had a craving for pizza so he exchanged 10,000 units of a (at that time) unpopular asset for something he wanted - the pizza.
Bitcoin for two pizzas. Was it that he was so hungry or just didn't care anymore about his Bitcoin and wanted to get rid of them?
What do you mean anymore? Stop thinking of bitcoin in today's age and time. We are talking about the beginnings were it wasn't yet valuable. There was no "anymore" in those days.
Unfortunately he later regretted selling that Bitcoin back then which could have been worth Rs 22,60,68,90,000 today. I guess he just never taught of this before he made that decision.
I think he wrote somewhere on the forum that he never regretted the decision and at the time it made sense to him. If no one spends bitcoin today thinking the value will be much higher in the future, it would never end. No matter what price it reaches, people would say, not yet, let's wait a little bit more.
