Browser-based crypto mining: an easy way to earn or a dangerous trap?

Have you ever wondered if you can earn crypto just by sitting on the internet? Browser mining promises exactly that — profit without expensive equipment. But is it really that simple?

The History of the Return of an Old Idea

Browser mining emerged back in 2011, but it truly made a comeback in 2017 alongside the crypto boom. At that time, it was indeed an innovation: users could embed JavaScript code on websites, and visitors would automatically “work” for the miners behind the scenes.

How does it work in reality?

The principle is simple: you download a special browser ( such as CryptoTab or Brave ), create an account, and while you are surfing the web, the system uses the power of your device to solve cryptographic tasks. Rewards are automatically sent to your wallet.

The most suitable currency for browser mining is considered to be Monero (XMR) — its RandomX algorithm is specifically designed for general-purpose processors, rather than expensive ASIC miners. This is done to maintain the decentralization of the network.

Why is this attractive?

✓ Zero investments in equipment ✓ Saving on electricity (browser consumes much less than ASIC) ✓ Available to everyone with a stable internet connection ✓ Full control — you can start/stop mining at any time

But there is a serious catch — crypto-jacking

The dark side: many malicious websites embed mining scripts WITHOUT your consent. This is called cryptojacking. Your computer works for someone else, the battery drains quickly, and you get nothing.

Security is the main issue

Cryptocurrency browsers depend on server security. If the server is compromised, an attacker can gain access to your wallets. Therefore:

— Use only verified browsers (Brave, official CryptoTab) — Regularly update the software — Choose complex passwords — Avoid suspicious websites

Is it really profitable?

Income depends on your PC's power, the current crypto price, and network difficulty. Realistic? You can earn from $1 to $20 per month with the browser working continuously — more of an interesting hobby than serious earnings.

Conclusion: browser mining has a right to exist if you use legitimate tools and understand the risks. However, you shouldn't expect a large income. It's more of a passive earning from the unused resources of your device.
