Smart Contract Audits: What They Catch, What They Miss

Cryptocurrency Miners is an independent crypto news and education publication with a real mining specialism. We cover Bitcoin, altcoins, blockchain technology, trading and NFTs and Web3, and, unlike most crypto news sites, we cover mining properly: The Miner's Dashboard with live hashrate, difficulty, block reward and halving countdowns, honest hardware coverage, and clear proof-of-work versus proof-of-stake guides.

The domain was registered in 2025 and the publication relaunched in its current form in 2026. We state it that way deliberately rather than claiming an older, more established-sounding founding date, because an inflated history is exactly the kind of trust signal a reader cannot verify and should not have to take on faith.

No. We are a news, education and data publication. We do not custody funds, run a mining pool, sell hardware, or operate any trading product. Nothing here asks for your wallet, your seed phrase or your keys, and no legitimate service ever will.

No. All content, The Miner's Dashboard and every tool are free and work without registration. There is no paywall and no sign-up wall. The only optional email we collect is for The Hashrate newsletter, which you can leave at any time.

It is a live board of the metrics miners actually watch: network hashrate, mining difficulty, the current block reward, block height and the next-halving countdown, for Bitcoin, Litecoin, Dogecoin and Bitcoin Cash. Data is proxied from public block explorers on our own server. It also carries a profitability estimator that combines that live network state with your hardware and electricity inputs.

It depends, and it changes constantly. Profitability is decided by your electricity cost, hardware efficiency, network difficulty, the block reward and the coin price. Our calculator gives an estimate from your inputs and the live network state; it is never a guarantee and never advice. At many consumer electricity rates, current-generation hardware does not cover its power cost, and we will show you that plainly rather than hide it.

A halving is a scheduled cut to a chain's block reward, written into its protocol. Bitcoin halves roughly every four years, or every 210,000 blocks, and Litecoin every 840,000 blocks. It matters to miners because it halves the revenue side of their economics on a known date while their costs stay the same. The Miner's Dashboard shows a live countdown.

It depends on the coin and algorithm, your budget, your electricity cost and your goals. Where a mature ASIC market exists, such as Bitcoin's SHA-256 or Litecoin's Scrypt, general-purpose hardware is not economically competitive. GPUs remain relevant only on algorithms that resist specialised hardware. There is no single right answer, and this is not financial advice.

Yes. The Miner's Dashboard currently tracks Bitcoin, Litecoin, Dogecoin and Bitcoin Cash, covering both the SHA-256 and Scrypt algorithm families, and we cover the hardware that targets them. We also cover staking for proof-of-stake coins, since that is where the equivalent yield question lives for non-mineable assets.

Network hashrate, difficulty, block reward and block height come from public block explorers, primarily Blockchair, with mempool.space and blockchain.info as fallbacks for Bitcoin. The halving countdown is computed from live block height and each chain's protocol schedule rather than being read from any single source. Coin prices come from our keyless price layer. Everything is cached server-side and dated.

Coin prices and the ticker refresh on a short cycle, typically under a minute. Network hashrate and difficulty refresh roughly every ten minutes, which matches how quickly those figures meaningfully move. Block height and the halving countdown follow the same cycle, with the countdown ticking live in your browser. Every surface shows when it was last updated.

Because the inputs differ. Many calculators assume a default electricity rate, ignore pool fees, or use a stale difficulty figure. Ours uses the live network hashrate and the block reward computed from current block height, applies your stated pool fee, and shows the power cost separately so you can see exactly which side of the equation is hurting. We publish the formula in our methodology.

It is a market-sentiment gauge scored from 0 to 100, published by Alternative.me and shown in our header for context. Low readings indicate fear, high readings greed. It is a sentiment summary, not a prediction, and it should never be used on its own as a reason to buy or sell anything.

No. Everything here, including news, analysis and mining profitability figures, is informational and educational only, not financial advice. Crypto and mining are volatile and you can lose money. Hardware can stop covering its own electricity cost. Always do your own research, and speak to a qualified professional before committing money.

Our hardware coverage is research-based and clearly labelled as such, built from manufacturer specifications, public teardowns and operator reports. Where a genuine hands-on test has happened, we say so and label it explicitly. We never claim to have run a rig we did not run, and we never publish a fabricated rating.

Editorial content is published under the Cryptocurrency Miners editorial desk, an honest collective byline, with a human editor accountable for every claim. We do not invent named personas, fake biographies or stock-photo author headshots, and we do not publish under a raw admin account. If named journalists join and consent to a public profile, they will appear with genuine credentials.

No. Editorial prose is written by people. Our live data is machine-generated in the sense that it is computed from public sources, which is exactly what it should be, and we document how in our methodology. What we do not do is publish spun or synthetic articles as though a person reported them.

Through advertising and clearly disclosed affiliate links, for example to mining hardware retailers and exchanges. We never take payment for favourable coverage, and affiliate status never changes a verdict or a number. Affiliate links are kept off safety-critical content. Our full position is set out in the affiliate disclosure.

Proof of Work secures a network with computation and energy: miners race to find valid blocks, and the cost of that work is what makes rewriting history expensive. Proof of Stake secures it with capital instead: validators post coins as collateral and can lose them for misbehaving. We cover both, including mining on the one side and staking on the other, without pretending either is objectively correct.

Start with the Learn section and the Beginner Trading Guides, especially How Blockchain Works and Top Exchanges and Wallets, and keep the Glossary open in another tab. If mining is what brought you here, read the proof-of-work versus proof-of-stake explainer before you look at any hardware, and run the profitability calculator with your real electricity rate before you spend anything.
