Buying pizza with 10,000 bitcoin is what I don't think I can forget, it's kind of funny but I believe if the person knows that bitcoin will get to the current price he or she won't even try it, I believe most of them believe that bitcoin will survive, I know the person will definitely regret buying pizza for 10,000 bitcoin but is late already.
according to some articles I read, in fact the pizza buyer or "Bitcoin Pizza guy" Laszlo Hanyecz doesn't regret buying 2 pizza pans with 10,000 BTC, he thinks that he has become a part of bitcoin history and people know him through transactions first bitcoin pizza. Laszlo Hanyecz is also a programmer from Florida and is currently assisting the crypto forum technical digabian to fix bugs and other things.
Yes as per his statement he doesn't regret dealing 10k bitcoins for just two pizzas but deep inside we know that he might be feeling really bad because that bitcoins are worth millions today so it can't be missed.Although there is one day specially dedicated towards it and known as bitcoin pizza day starting from him.
