A Bitcoin discussion board submit printed on Sept. 7, 2010, has resurfaced 16 years later after an early miner described a projected $5.68 electrical energy invoice for mining a 50 $BTC block as “a internet loser.”
The calculation was real, however it didn’t imply that spending $5.68 assured the miner a block. The determine represented an anticipated electrical energy price based mostly on the miner’s computing energy, Bitcoin’s issue and the typical time wanted to discover a legitimate block.
The discussion board participant, utilizing the identify TTBit, measured a pc consuming 140 watts whereas producing about 2,200 kilohashes per second. A mining calculator estimated a mean wait of 338.05 hours, or roughly 14 days and two hours.
Operating a 140-watt machine for that interval would eat roughly 47.33 kilowatt-hours. At $0.12 per kilowatt-hour, the electrical energy invoice could be $5.68. The arithmetic within the authentic submit is due to this fact constant.
“It could price me 47.327 Kwh to supply a block,” TTBit wrote, earlier than calling the projected expense “a internet loser.”
An Web discussion board consumer 16 years in the past measured their pc’s electrical energy use and estimated it will take roughly two weeks to supply a Bitcoin block. With the block mining subsidy then 50 bitcoin, their estimated electrical energy price was $5.68, which they referred to as “a internet loser” pic.twitter.com/1YE68hzOCE

That conclusion mirrored Bitcoin’s restricted market and liquidity in 2010. It shouldn’t be learn as proof that the miner rejected a assured 50 $BTC cost.
Bitcoin mining was already a likelihood contest
Bitcoin mining has by no means promised a block after a hard and fast variety of hours. Miners repeatedly hash block headers, trying to find a end result beneath the community’s goal. Each try has a likelihood of success.
The 338-hour determine was a mean derived from TTBit’s 2.2-megahash-per-second charge and the problem at the moment. The miner might have discovered a block instantly, waited for much longer than 14 days or by no means discovered one earlier than issue modified.
This distinction issues as a result of some retellings describe $5.68 because the mounted manufacturing price of fifty $BTC. It was as an alternative the electrical energy price related to an estimated solo-mining interval. {Hardware} prices, cooling, web service and tools failure weren’t included.
Miners now generally be part of swimming pools, which mix computing energy and divide earnings in line with contributed work. Pooling doesn’t change the anticipated financial return earlier than charges, however it reduces the acute variation confronted by a solo miner.
A contemporary instance reveals that the lottery-like ingredient stays. In July 2026, a small Bitaxe miner discovered block 957,382 and picked up 3.1382 $BTC, together with charges, as crypto.information reported. Such outcomes are potential, however they don’t set up regular profitability for small machines.
Bitcoin’s 50 $BTC subsidy had little greenback worth
The Bitcoin protocol initially awarded 50 $BTC for every legitimate block. Its guidelines cut back that subsidy by half each 210,000 blocks, or about as soon as each 4 years, in line with the developer documentation.
Bitcoin had no deep or standardized market in September 2010. Historic worth data fluctuate as a result of buying and selling came about throughout small exchanges and casual transactions. Out there data point out that Bitcoin remained beneath $1 all through 2010, with estimates generally inserting late-2010 costs between $0.10 and $0.30.
The exact market worth on the discussion board submit’s date is tough to ascertain. That makes the consumer’s “internet loser” description a private evaluation slightly than a universally verifiable revenue calculation. Promoting 50 $BTC might additionally contain restricted liquidity and counterparty threat.
At Bitcoin’s present worth of roughly $78,810 on Sept. 8, 2026, 50 $BTC could be value about $3.94 million. That comparability makes use of right this moment’s market worth and doesn’t characterize worth {that a} miner might reliably receive in 2010.
The community now not points 50 $BTC per block. The April 2024 halving lowered the subsidy from 6.25 $BTC to three.125 $BTC. Transaction charges are added to that subsidy, so the entire block reward varies.
For a broader clarification of the issuance schedule, associated protection of Bitcoin’s halving explains how every discount locations recent stress on miners whose prices don’t fall on the similar charge.
GPU mining was starting to interchange residence CPUs
TTBit’s submit captured a technical transition already underway. The miner in contrast the pc’s 2,200 kilohashes per second with experiences of graphics playing cards producing roughly 25,000 kilohashes per second.
One other participant reported round 33,000 kilohashes per second from an Nvidia GTX 260 whereas drawing roughly 200 watts. On these reported figures, the graphics card produced about 10 occasions extra hashing work per watt than TTBit’s CPU-based setup.
The dialogue additionally included a submit attributed to Bitcoin creator Satoshi Nakamoto, who estimated {that a} 24-core AMD system might attain roughly 66,000 kilohashes per second. These figures had been casual experiences from discussion board individuals slightly than standardized {hardware} benchmarks.
Nonetheless, they documented the aggressive drive shaping Bitcoin mining. As soon as one group gained entry to extra environment friendly {hardware}, different miners wanted to improve or settle for a smaller likelihood of discovering blocks.
Graphics processors later gave method to field-programmable gate arrays after which application-specific built-in circuits, or ASICs. Trendy Bitcoin ASICs are constructed particularly to calculate SHA-256 hashes and function at terahashes or petahashes per second slightly than kilohashes.
TTBit’s machine produced 2.2 million hashes per second. Stay analytics on Sept. 8 positioned the whole Bitcoin community close to 966 exahashes per second, though hashrate is inferred from issue and up to date block manufacturing slightly than measured instantly. That community estimate is about 439 trillion occasions the pace of the pc described within the submit.
Bitcoin mining prices stay decisive in 2026
The dimensions has modified, however the query raised in 2010 stays central: does the anticipated Bitcoin income exceed the price of electrical energy and tools?
Bitcoin’s issue adjusts each 2,016 blocks to maintain common block manufacturing shut to 10 minutes. When extra computing energy joins, the protocol usually raises issue. When miners disconnect and blocks gradual, it lowers issue.
Stay estimates positioned issue close to 127.45 trillion on Sept. 8. That determine can change at every adjustment, whereas shorter hashrate readings can fluctuate as a result of block arrivals are random.
Mining situations weakened throughout components of 2026. Bitcoin’s issue fell 19.9% from its November 2025 peak to about 126.23 trillion by late July, as beforehand reported. Estimated hashrate additionally retreated from ranges above one zettahash per second.
These actions supplied some reduction to miners that remained on-line, however they didn’t make CPU mining aggressive once more. Industrial operators usually negotiate electrical energy contracts, deploy hundreds of ASICs and handle cooling, upkeep and financing prices.
The 2010 dialogue additionally anticipated one function of that competitors. TTBit wrote that it might turn out to be “fairly tough to generate cash” if the development continued. That was a forecast, not a certainty on the time, however the path proved right as specialised machines displaced general-purpose computer systems.
What occurs subsequent for Bitcoin miners
Bitcoin’s subsequent scheduled halving is anticipated round 2028, relying on the tempo at which blocks are produced. It should cut back the block subsidy from 3.125 $BTC to 1.5625 $BTC.
The date can’t be identified precisely prematurely as a result of particular person block occasions fluctuate. The protocol triggers the discount at a block peak, not on a hard and fast calendar day.
Till then, miners will proceed responding to Bitcoin’s worth, transaction charges, issue, vitality costs and {hardware} effectivity. Operators with excessive energy prices or older machines could disconnect when anticipated income falls beneath working bills.
Some giant mining corporations have additionally directed energy capability towards synthetic intelligence and high-performance computing. In associated mining protection, a number of operators generated rising income from>FAQs
Did $5.68 assure the miner 50 $BTC?
No. The miner calculated the electrical energy required throughout an estimated common ready interval. Solo mining remained probabilistic, and the precise wait might be shorter or considerably longer.
Was 50 $BTC the complete reward in 2010?
The protocol’s block subsidy was 50 $BTC. A profitable miner might additionally accumulate eligible transaction charges, though charges had been minimal throughout Bitcoin’s early interval.
Why did the miner think about 50 $BTC unprofitable?
Bitcoin had restricted liquidity and a really low market worth. The poster’s conclusion mirrored the anticipated electrical energy expense in contrast with the worth obtainable at the moment.
May a house pc mine Bitcoin right this moment?
A pc can technically submit hashes, however strange CPUs and GPUs can not compete economically with fashionable SHA-256 ASICs. A house miner’s solo likelihood could be extraordinarily small.
What’s the present Bitcoin block subsidy?
The subsidy is 3.125 $BTC per block following the April 2024 halving. The following discount is anticipated round 2028.
