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..
It must be admitted that Laszlo played a significant role in changing the future of Bitcoin to what it is today, in addition to being a major player in fixing many vulnerabilities in the early stages of the Bitcoin network, he was also the first developer to release Bitcoin code for Mac OS. He continues to demonstrate his genius in Bitcoin technology by changing the mining landscape. Yes, before the advent of integrated chips (ASIC), at that time Bitcoin was mined using CPU. He then managed to develop a mining code transition that allowed miners to mine Bitcoins that previously used CPU to switch to GPU.
Satoshi had time to establish communication with him, he assumed GPU mining was too advanced for Bitcoin at the time, so it was no surprise that he managed to find 200 blocks or more in mining. The 10k bitcoin reward he received for mining (50 BTC per block) allowed him to do whatever he wanted, 10,000 Bitcoins for 2 Pizzas was recorded as his first transaction, perhaps by then he had spent even more Bitcoins to order his favorite food.
