Is it more profitable to mine Monero or Bitcoin?

Monero is usually the more practical coin to mine with a computer you already own, but that does not guarantee a profit. Bitcoin can be more profitable if you have specialized mining machines and very cheap electricity. If you mean mining in your web browser, neither is a reliable way to earn money after costs.

Your hardware decides which comparison makes sense

Monero and Bitcoin reward miners for using computing power to help secure their networks. But they are designed for very different equipment.

Monero uses RandomX, a mining method that favors CPUs—the main processors inside everyday computers. You can try it without buying a dedicated mining machine, though an efficient desktop processor usually has a better chance than an older laptop.

Bitcoin mining is dominated by ASICs, machines built specifically to perform Bitcoin’s mining calculations. Your laptop or desktop cannot compete economically with them.

That gives you a useful starting point:

• Already own a computer? Monero is the realistic option to test.
• Have cheap power and money for specialized equipment? Bitcoin may be worth comparing.
• Only want to use a browser? Expect very limited earnings, not a dependable income.

Compare profit, not the coins you receive

Mining revenue is the value of the coins you earn. Profit is what remains after expenses.

For either coin, your basic calculation is:

Profit = mining revenue − electricity − fees − equipment costs

Include cooling and maintenance where they matter. If you buy hardware, you also need to recover its purchase price before you have made an overall profit.

For example, a computer drawing an extra 100 watts continuously uses 2.4 kilowatt-hours each day. A kilowatt-hour is the unit your electricity supplier bills you for. Multiply 2.4 by your electricity rate to estimate that daily cost.

Bitcoin equipment can produce much more revenue than a household CPU, but it also costs more and typically consumes far more power. More revenue does not automatically mean better profit.

Also compare returns in your local currency, not the number of coins earned. One XMR and one BTC have different values.

Browser mining changes the answer

Mining Monero in a browser generally performs worse than using a dedicated mining program. Browser limits and implementation choices can prevent your processor from working as efficiently.

RandomX also needs substantial memory. Its fast mode uses a dataset of about 2,080 MB, plus additional working memory. That makes efficient browser mining challenging.

Bitcoin mining directly in a normal browser is not economically competitive with ASICs. If a website promises meaningful Bitcoin earnings from your browser, check what it actually does. It may pay rewards in Bitcoin without your device mining Bitcoin at all.

Be especially cautious about guaranteed returns, unclear withdrawal rules, or demands for a deposit to unlock earnings.

The bottom line

For your existing computer, Monero is generally the better mining choice—but switching it off may still be more profitable if electricity costs exceed earnings. Bitcoin only becomes a serious comparison when you consider specialized hardware, cheap power, and operating costs.

Before spending money, use a live mining calculator with your measured power use, electricity rate, hardware speed, and fees. Check several price and mining-competition scenarios rather than trusting one estimate. If you are mining through a browser, treat it as an experiment first, not an investment plan.
