The Hardware/Software Landscape
On May 22, 2010, Laszlo Hanyecz made history by purchasing two Papa John’s pizzas for 10,000 Bitcoin — a transaction worth approximately $41 at the time. Eight years later, on May 22, 2018, those same 10,000 Bitcoin were worth over $80 million at the day’s trading price of $8,041. The anniversary, celebrated annually as Bitcoin Pizza Day, served as more than just a quirky footnote in cryptocurrency history. It was a stark reminder of how dramatically the mining landscape had transformed in less than a decade.
In 2010, Hanyecz had mined his Bitcoin using a standard consumer GPU — likely an ATI Radeon — on his home computer. The Bitcoin network’s total hashrate at the time was measured in mere megahashes per second, and mining was a hobbyist’s pursuit that anyone with a decent graphics card could pursue profitably. Fast forward to May 2018, and the mining industry was dominated by application-specific integrated circuits, or ASICs, with Bitmain’s Antminer S9 reigning supreme at 14 terahashes per second while consuming 1,372 watts. The network hashrate had ballooned to approximately 35 exahashes per second — a million-fold increase from the GPU mining era that produced those famous pizzas.
Hashrate and Difficulty
The contrast between 2010 and 2018 mining difficulty illustrates the industrialization of Bitcoin extraction. When Hanyecz bought his pizzas, mining difficulty was measured in the low thousands. By May 22, 2018, Bitcoin’s mining difficulty had reached approximately 4 trillion — a figure that would have been incomprehensible to early miners. Each difficulty adjustment, occurring every 2,016 blocks or roughly two weeks, reflected the relentless influx of new hashing power onto the network.
The global distribution of mining operations had also undergone a radical transformation. In 2010, mining was distributed among hobbyists across the developed world. By May 2018, an estimated 60 to 70 percent of Bitcoin’s hashrate was concentrated in China, particularly in provinces like Sichuan and Yunnan that offered cheap hydroelectric power during the rainy season. The migration of mining operations from garage setups to purpose-built industrial facilities represented one of the most dramatic industrial pivots in modern technology history. Regions like Quebec in Canada had also attracted significant mining investment, though the events of this very week — with Hydro-Québec publishing its critical economic impact report — were beginning to reshape that landscape.
Profitability Metrics
Consider the economics from both ends of the eight-year timeline. In 2010, Hanyecz’s mining rig likely consumed a few hundred watts of power to generate Bitcoin that was virtually worthless — each BTC was worth less than half a cent. The electricity cost to mine those 10,000 BTC was probably under $10 total. By May 2018, mining a single Bitcoin required roughly 55,000 terahashes of computational work, translating to electricity costs of $2,000 to $5,000 depending on the miner’s location and hardware efficiency.
An Antminer S9 operating at 14 TH/s with electricity at 5 cents per kWh was generating approximately $4 to $6 in daily revenue above electricity costs on May 22, 2018. For a mining farm running hundreds or thousands of these units, daily revenue could reach tens of thousands of dollars — but capital expenditure was equally staggering. Each S9 retailed for around $2,000 to $3,000 in early 2018, meaning a 1,000-unit operation required $2 to $3 million in hardware investment alone, plus infrastructure costs for cooling, power distribution, and facility construction.
Environmental Impact
The Pizza Day comparison throws Bitcoin’s energy consumption into sharp relief. The electricity used to mine Hanyecz’s original 10,000 BTC in 2010 was negligible — comparable to running a desktop computer for a few weeks. By May 2018, the Bitcoin network was consuming an estimated 45 terawatt-hours annually according to the International Energy Agency, placing its energy footprint on par with countries like New Zealand or Hungary. Each Bitcoin transaction was estimated to require hundreds of kilowatt-hours of electricity.
The environmental scrutiny was intensifying in real-time. Just days before Pizza Day 2018, researchers had published analyses in journals like Joule showing that Bitcoin’s energy consumption was growing faster than many had predicted. The proof-of-work consensus mechanism that secured the network — the same mechanism that had been so simple in 2010 that a single GPU could participate — now required industrial-scale infrastructure with genuine environmental consequences. Critics argued that the energy expenditure was wasteful, while proponents countered that the network’s security and censorship resistance justified the cost, particularly when powered by renewable sources.
Strategic Outlook
Bitcoin Pizza Day 2018 arrived at a moment of reckoning for the mining industry. Bitcoin had fallen from its December 2017 peak near $20,000 to roughly $8,000, squeezing miner margins and forcing less efficient operations to shut down. The halving cycle — which would cut block rewards from 12.5 to 6.25 BTC in 2020 — loomed as an existential challenge for miners who had invested heavily in infrastructure based on 2017’s euphoric economics.
Yet the trajectory from Hanyecz’s GPU to industrial ASIC farms suggested that Bitcoin mining would continue to evolve. The next generation of mining hardware was already in development, with companies like Bitmain, Canaan, and Ebang competing to produce more efficient chips. The geographic diversification of mining away from China was accelerating, driven by regulatory uncertainty and the search for ever-cheaper electricity. And the fundamental economic proposition — that Bitcoin’s fixed supply would eventually make each unit more valuable — continued to attract capital and talent to the mining sector. Eight years after two pizzas changed history, the question wasn’t whether Bitcoin mining would survive, but rather what the industry would look like when Pizza Day 2028 rolled around and the block reward had been halved twice more.

10000 btc for two pizzas. at 80 million that is 40 million per pizza. the most expensive meal in human history
thats only counting 2018 prices. at current BTC prices those pizzas cost more than most houses
from gpu mining in 2010 to ASIC farms in 2018. the hashrate went from megahashes to exahashes. pizza day isnt about the pizza its about how fast bitcoin mining became an industry
Hanyecz mined those coins on a GPU. From megahashes to exahashes in eight years. The hashrate growth tells the real story of Bitcoin adoption.
the S9 was the workhorse of 2018 mining. 14TH at 1372W seems ancient now but those machines built fortunes
S9 was the GOAT. ran a small farm of them in 2018, ROI was tight but the machines were tanks
14 TH at 1372W on the S9. my garage was basically a sauna running those through 2018 winter
ran 6 S9s through the 2018 winter in my garage. electricity cost was brutal but those machines paid for themselves 3 times over by 2021
35 exahashes by 2018 vs laszlo mining on a single ATI Radeon in 2010. the hashrate graph is the most bullish chart in crypto history
blockfi_survivor that million-fold increase from MHash to EH/s is wild. S9 at 14 TH/s was state of the art and now a single S21 does 200+
Anders P. the jump from S9 at 14TH to S21 at 200+ TH is insane. mining hardware generations define entire eras of Bitcoin profitability
10k BTC for pizza in 2010 and 8 years later thats an $80M meal. the GPU to ASIC transition is what really tells the story though
Pizza Day is fun but the real lesson is about time preference. Holding through years of volatility is the hardest part.
time preference is the real lesson. laszlo spent 10k btc on pizza because he valued pizza over future wealth. most of us would have done the same in 2010
laszlo said he had no regrets. dude just wanted pizza and made history. absolute legend
41 bucks for two pizzas and eight years later its 80M. every pizza day i remember the altcoins i spent on coffee in 2013 and cry a little
10k btc for two pizzas and 8 years later its an 80 million lesson. the gpu to asic jump is what really changed the game though
S9 at 14TH pulling 1372W was a space heater that occasionally paid you. ran three through winter 2018 and my garage was 40 degrees warmer than outside
s9_survivor_ knows. antminer s9 at 14TH pulling 1372W was the real workhorse. ran 4 of those through winter 2018 and barely broke even
s9_survivor_ those machines were tanks. bought 5 used S9s in late 2018 and they still mined profitably through 2020. try doing that with any modern ASIC
Chulmin Y. S9s were tanks. 5 used machines mining through 2020 on the pizza day anniversary is wild
s9_survivor_ ran 4 S9s through winter 2018 too. garage was basically a sauna but those machines were indestructible. try running a modern ASIC for 3 years
Laszlo mined 10k BTC on a GPU in 2010 and bought pizza. no regrets from him apparently. guy just wanted lunch and accidentally made history
Laszlo mining 10K BTC on an ATI Radeon in 2010. the jump from megahashes to 35 exahashes in 8 years is the most bullish chart in crypto
S9 at 14TH pulling 1372W was a space heater that paid you. ran three through winter 2018 and barely broke even but those machines were tanks
