How Does the ViaBTC Mining Guide Explain Bitcoin Mining?

Bitcoin mining is a competition to produce valid SHA-256 proof of work, not a process in which an ASIC simply “creates” BTC. Bitcoin began in 2009, its block subsidy started at 50 BTC, and the 2024 halving reduced it to 3.125 BTC at block 840,000. ViaBTC’s guide explains the operating chain around that protocol: choose compatible ASIC hardware, supply stable power and cooling, connect through Stratum, submit accepted shares, monitor pool-side hashrate, and receive payouts under a selected settlement method. Recent ViaBTC network data listed Bitcoin at roughly 1,044 EH/s with difficulty around 127.17 T, showing the scale facing an individual machine. Profit depends on effective hashrate, electricity use, uptime, network difficulty, pool fees, transaction fees, and BTC price together, so a 200 TH/s ASIC cannot be evaluated from its advertised hashrate alone.

Bitcoin’s mining process starts with a candidate block assembled from valid transactions. Mining hardware repeatedly hashes block-header data and changes available inputs until the resulting hash is below the network target. One terahash per second equals 1 trillion attempts per second; 200 TH/s therefore represents about 200 trillion hashing attempts every second. ViaBTC’s published material uses TH/s, PH/s, and EH/s because modern Bitcoin mining has moved far beyond the CPU-scale computing used around 2009.

A miner is not solving one long mathematical problem. It is making an enormous number of independent SHA-256 attempts, with each attempt having a very small probability of satisfying the current target.

That probability explains why network scale matters. ViaBTC recently displayed network hashrate near 1,044.04 EH/s. A 200 TH/s miner represents only about 0.000019% of 1,044 EH/s before considering downtime or rejected work. Adding another identical ASIC roughly doubles the operator’s share, but the operation remains tiny compared with the entire network; the next issue is how Bitcoin keeps block production from accelerating whenever more machines come online.

Bitcoin addresses that issue through mining difficulty. The protocol targets an average block interval of about 10 minutes and reassesses difficulty every 2,016 blocks, roughly 14 days at the intended pace. ViaBTC’s network data recently showed difficulty around 127.17 T and an estimated next adjustment of about -1.03%; figures change with network conditions, so miners should read them as current measurements rather than permanent assumptions.

A simple example shows why difficulty deserves attention. Suppose one operation contributes 1 unit of computing power to a network totaling 100 units: its simplified share is 1%. If the network expands to 125 units while the miner stays at 1, its share falls to 0.8%, a 20% reduction in relative share. ViaBTC uses this type of comparison to explain why a machine can operate normally while its expected BTC output changes.

The reward side has changed just as much. Bitcoin’s original subsidy was 50 BTC per block in 2009 and halves every 210,000 blocks. The subsidy became 25 BTC in 2012, 12.5 BTC in 2016, 6.25 BTC in 2020, and 3.125 BTC at block 840,000 in 2024. The 3.125 BTC subsidy remains in place until block 1,050,000, while transaction fees provide an additional, variable part of each block’s miner compensation.

A 50% subsidy cut does not automatically produce a 50% drop in every miner’s dollar revenue because BTC price, transaction fees, difficulty, network hashrate, pool settlement rules, and machine uptime can move at the same time. The table instead shows why electricity efficiency becomes more important after successive halving eras: the protocol issues fewer new BTC per block while miners continue paying for power every hour.

Hardware therefore has to be examined in watts as well as TH/s. ViaBTC’s educational material notes that modern Bitcoin mining relies on ASICs rather than the CPUs and GPUs common in earlier years. One example cited by ViaBTC, the Antminer S19 XP Hydro, reaches 257 TH/s on SHA-256; specifications alone still do not tell an operator whether the machine will cover electricity, cooling, maintenance, and equipment costs.

Consider a hypothetical 3.5 kW ASIC. Running 24 hours consumes 84 kWh per day, or about 2,520 kWh in a 30-day month. At $0.05/kWh, electricity costs about $126 per month; at $0.08/kWh it rises to $201.60, a 60% increase. At $0.12/kWh, the same hardware uses about $302.40 of electricity monthly before cooling, hosting charges, pool fees, repairs, or capital cost are counted.

Efficiency can be compared in joules per terahash. A 200 TH/s machine consuming 3,500 W operates at 17.5 J/TH, while another 200 TH/s machine drawing 4,500 W operates at 22.5 J/TH. The second machine consumes about 28.6% more power for the same nominal hashrate, which can materially change operating margins across thousands of continuous hours.

That cost comparison leads naturally to uptime. A miner advertised at 200 TH/s but online only 95% of the month delivers roughly 190 TH/s of time-adjusted nominal capacity before rejected or stale shares are considered. At 90% uptime, the figure falls to about 180 TH/s. ViaBTC advises monitoring worker status, average hashrate, accepted and rejected shares, temperature, fan behavior, hardware errors, reward records, and connection status over hours and days rather than relying on one screen reading.

A local ASIC dashboard and pool-side reporting measure performance from different positions. Short-term readings do not have to match exactly because pool hashrate is estimated from submitted work over a measurement window.

Pool-side measurement matters because a mining pool cannot pay miners merely from the hashrate printed on an ASIC’s specification sheet. Pools use submitted shares to measure contributed work. A share proves that the machine found a hash meeting the pool’s assigned share difficulty; it normally does not meet Bitcoin’s much harder network target and therefore is not itself a Bitcoin block. ViaBTC tracks accepted shares and estimated hashrate from this submitted work.

That distinction also explains why pool mining differs from solo mining. A solo miner receives the applicable block compensation when it independently finds a valid block, but a small operator can face very long periods without one. A pool combines many participants’ hashrate and allocates proceeds according to its settlement rules. The pool does not increase an individual ASIC’s 200 TH/s capability; it changes the frequency and distribution of payments.

Pool size affects the statistics of block discovery. ViaBTC reported in 2026 that its BTC blocks mined over the preceding year represented approximately 12% of Bitcoin’s total, while the company states that it serves more than 2 million users. A pool controlling a larger percentage of network hashrate would generally be expected to find blocks more frequently over a sufficiently long period, although short periods can still differ from statistical expectation.

Miners can inspect current ViaBTC Pool Hashrate alongside network conditions rather than judging a pool only from its brand or historical rank. Pool hashrate mainly affects expected block frequency; it does not guarantee a higher net result for each participant. A miner’s own effective hashrate, pool fee, settlement method, electricity price, rejected-share rate, and uptime remain separate variables.

ViaBTC also explains three settlement choices: PPS+, PPLNS, and Solo. PPS+ credits valid shares under its stated payment rules and includes a transaction-fee component; PPLNS bases payment on the miner’s proportion of the last N shares around blocks found by the pool; Solo preserves a much more block-dependent outcome. ViaBTC’s 2025 guide described PPS+ as suitable for miners seeking steadier payment timing and discussed PPLNS for operators willing to accept greater short-term variation.

Before any payout method matters, however, the ASIC has to communicate reliably with the pool. ViaBTC’s 2026 setup guide describes a normal configuration as a pool account, worker name, current Stratum server address, compatible electrical supply, cooling, network access, and any required payout address. Wired Ethernet is recommended where possible because interrupted connectivity can reduce submitted work.

Stratum provides the communication layer between ASIC and pool. ViaBTC describes a Stratum address as containing a protocol, hostname, and port; one documented BTC example uses port 3333. A wrong character in the server information, an unsupported protocol, or an incorrect worker name can leave a miner offline or cause work to be associated incorrectly, so current connection information should come from the pool’s official configuration page.

Once connected, accepted-share percentage becomes more informative than a simple “online” label. If 99% of submitted shares are accepted, roughly 1% are not being credited as accepted work; if acceptance falls to 95%, the gap has increased fivefold relative to a 1% rejection baseline. Network latency, stale jobs, configuration errors, firmware problems, and unstable connections can all affect what the pool receives, so several hours of pool-side records give a better picture than a single minute.

Operating temperature and cooling belong in the same review because every watt consumed by an ASIC eventually becomes heat that must leave the room or facility. Ten machines drawing 3.5 kW each create a 35 kW continuous electrical load and consume 840 kWh every 24 hours. At $0.07/kWh, the ASICs alone use $58.80 of electricity per day, before ventilation or other facility equipment is added.

For a larger installation, small percentages become large dollar amounts. A 1 MW mining site running at 95% average utilization consumes about 684,000 kWh in a 30-day month. At $0.05/kWh, that is approximately $34,200 in electricity; a 10% increase in the tariff raises the energy bill by about $3,420 for the same consumption. Hardware selection therefore cannot be separated from the electricity contract and expected operating hours.

Mining revenue should be examined with the same discipline. ViaBTC explains expected output as the miner’s effective hashrate relative to total network hashrate, combined with available mining rewards and then adjusted for factors such as pool fees, settlement method, downtime, and rejected shares. If network hashrate rises 25% while a miner’s own hashrate remains unchanged, the miner’s relative network share falls from 1% to 0.8% in the simplified 100-to-125 example.

Bitcoin price adds another layer because operating bills are usually paid in local fiat currency while mining output is denominated in BTC. ViaBTC recently displayed BTC near $64,176.63 while listing approximately 939,187.5 BTC, or 4.47% of the 21 million maximum supply, as remaining to be mined at that snapshot. Both price and network statistics can change quickly, so profitability estimates should use current measurements rather than figures copied from an older hardware review.

A practical review therefore uses several time windows. A miner can check connection and rejected shares over minutes, effective hashrate over hours, uptime and electricity over days, pool settlement over payout periods, and difficulty over the 2,016-block adjustment cycle. Comparing a single 10-minute interval with a monthly electricity bill mixes measurements that describe different periods and can give a misleading view of performance.

ViaBTC’s guide is most useful when read as an operating model rather than a promise of mining income. Bitcoin supplies the 10-minute block target, 2,016-block difficulty cycle, 3.125 BTC subsidy era, and SHA-256 competition; the ASIC supplies measurable TH/s at a measurable wattage; Stratum carries work between miner and pool; submitted shares provide pool-side accounting; settlement rules determine payment timing; electricity, cooling, fees, downtime, and BTC price determine whether the operation remains economically workable.
