Is XMR mining better than mining Ethereum Classic?

XMR mining is usually the better fit if you want to use a normal computer’s processor. Ethereum Classic mining makes more sense if you already have an efficient graphics card or dedicated mining machine. Neither is automatically more profitable: your hardware, electricity price, and mining software matter more than the coin’s name.

Start with the hardware you already have

Monero uses RandomX, a mining algorithm—the set of calculations your computer performs to help secure the network. It favors CPUs, the general-purpose processors inside everyday computers.

Ethereum Classic uses Etchash, an algorithm better suited to GPUs, or graphics cards, and compatible ASICs, machines built specifically for mining.

For you, that creates a practical split:

• A desktop with a capable CPU: XMR is usually the more sensible option to investigate.
• An existing graphics-card mining setup: ETC may make better use of your equipment, but compare it with other GPU-mineable coins.
• A compatible ASIC: ETC may be an option, though power costs and competition still matter.
• A thin laptop: Neither is especially attractive for earnings. Heat, fan noise, and wear can outweigh small rewards.

Ethereum Classic is not Ethereum. Ethereum stopped using mining in 2022; Ethereum Classic still uses it.

Compare net earnings, not advertised rewards

The useful comparison is net earnings: what you keep after electricity, fees, and equipment costs.

Monero produces blocks about every two minutes, with a continuing base reward of 0.6 XMR per block. That predictable supply does not mean predictable earnings for you. Your share changes with competition, and its cash value changes with XMR’s price.

ETC also has changing competition and a scheduled reduction in mining rewards over time. Neither reward schedule alone tells you which is better.

Use a live mining calculator with realistic inputs:

• Your measured hashrate, meaning how many mining calculations your hardware completes each second.
• Total electricity use measured at the wall.
• Your electricity rate.
• Pool and software fees. A pool combines miners’ work and shares payouts.
• Equipment purchase costs, if you are buying hardware.

Do not directly compare XMR and ETC hashrate numbers. Their calculations are different, so a bigger number does not necessarily mean better returns.

Browser mining changes the comparison

If you want to mine through a browser, XMR is the more relevant option—but browser convenience comes with major limits.

RandomX benefits from substantial memory and processor resources. Its fast mode uses a dataset of about 2,080 MB, and efficient operation generally needs about 2 MB of L3 cache per mining thread. L3 cache is fast memory inside your processor; a thread is one stream of work.

Browser restrictions and extra processing overhead can make performance much worse than dedicated mining software. Do not assume native-software calculator estimates apply to your browser.

Also check what a browser service actually mines. Some services mine another coin and pay you in XMR. Payment in XMR does not prove you are mining Monero.

The bottom line

Choose XMR first if you want to experiment with CPU mining on equipment you own. Consider ETC if you already have suitable graphics cards or a compatible ASIC and measured returns justify running them.

For browser-only mining, treat convenience as the benefit—not guaranteed profit. Test actual power use and accepted mining work before committing money, and avoid services promising fixed daily returns or demanding payment to unlock withdrawals.
