This dude (lazlo), I believe might have bought pizza worth 10k btc for global recognition of bitcoin.
We were only shown the amount of Bitcoin he spends when he bought pizza but trust me i am very certain that Lazlo had a lot of Bitcoin in his wallet. That wasn't his all in all.
It like he was paving the way for bitcoin to become a big deal, sometimes it takes a strategic plan and bold moves to push something into the spotlight. He might have done what he did for the greater good of bitcoin, Because at that time bitcoin was new and was not widely accepted as a form of payments but by using bitcoin to buy pizza a very popular food globally he was sending a signal of bitcoin utility. This act might have demonstrated the potentials of bitcoin beyond what regarded of it.
Lazlo must have had some serious foresight, because if it could be accepted as transaction at early stage when bitcoin is still new. Its hard to believe he wouldn't still have some bitcoin still left in his coffers. I believe he might have definitely kept some to see how it plays out in the future.
It wasn't a plan by Lazlo. His intention was as pure as another person craving to eat pizza. He never knew it would be worth what it is today and that he would be celebrated for making a decision like that in the future. Let me tell you something, he was not the only person who accepted Bitcoin as a means of payment. People were transacting with Bitcoin then too.
