I'm looking for free Bitcoin mining options and found these 8 choices worth testing. If you want to start earning with cryptocurrencies without spending anything, you can use your PC or even your phone for this.

I started with Awesome Miner, which runs on Windows and Linux. It’s from 2014, so it has a history. Then I discovered BetterHash, which is very intuitive and automatically chooses the most profitable coin to mine at the moment. BTC, ETH, ETC... you can mine several.

For those who only want Bitcoin, StormGain is well known. The good thing is that it doesn’t consume much energy and runs even on a phone. It has a Portuguese interface, which makes it quite easy. CryptoTab is different because it works as a browser—you mine while browsing the web, on Windows, Mac, Android, or iOS systems.

Kryptex is another Windows app that promises to pay for your PC’s power. According to them, you can earn around R$520 per month with a basic computer. ECOS is also a Bitcoin miner, but it charges—offers a free trial, but then it’s paid.

There’s more: PEGAPool is a mobile app that mines ETH, promising 0.01 ETH per day. MinerGate works on various systems and automatically chooses the most advantageous coin.

Bonus: EarnCrypto isn’t a traditional free Bitcoin miner, but you earn cryptocurrencies by doing simple tasks—watching ads, surveys, those kinds of things.

But hey, watch out for scams! There are many fake sites asking for personal data. Always check the platform’s credibility, its history, and what kind of security it uses to protect your data. Don’t fall for too-good-to-be-true promises of free Bitcoin, because there’s usually a trap behind.
