Just so you know, I tested several free cryptocurrency mining sites and found it interesting to share which ones work best. I started with Awesome Miner, which runs smoothly on Windows and Linux since 2014. The interface is very simple, just download and start mining, nothing complicated.

Then I tried BetterHash, which has that motto of getting your PC to work. The cool advantage is that it automatically chooses the most profitable coin to mine at the moment, so you don’t have to think about it. You can mine BTC, ETH, and ETC there.

Now, if you want to focus only on Bitcoin, StormGain is top. I know people who even use it on their phones, download the app, and activate mining. The good thing is it doesn’t consume much energy or crash the system. And it has a Portuguese interface, which makes it much easier for us here.

There’s also CryptoTab, which is quite creative because you mine while browsing. It works on Windows, Mac, Android, iOS. The referral system is interesting because it multiplies your earnings if you manage to get friends using it.

Kryptex is another one I recommend, especially if you have a simple PC. They say you can earn up to R$520 per month depending on your equipment. Install it, activate, and it runs automatically.

For those who only want Bitcoin, there’s ECOS too, but that’s cloud mining and ASIC, which is no longer free. It offers a trial period, but the costs can get heavy.

PEGAPool is interesting for mobile, you can mine ETH just with your smartphone. Download it from the Play Store and start with one click. They say you can get 0.01 ETH per day.

And there’s MinerGate, which is very versatile, runs on Windows, Mac, Linux, Android, iOS. The software itself chooses the most advantageous coin based on your device and market conditions.

Bonus: if you want to earn crypto without mining, there’s EarnCrypto too, where you complete tasks, watch ads, do surveys. It’s slower, but you earn some satoshis for free.

An important tip: when using any free cryptocurrency mining site, do thorough research on its history, see if it’s trustworthy, and what security measures they use. There are many scams out there promising free Bitcoin just to steal data. So be careful, verify the source, and then enjoy. The market is full of options, but not all are legitimate.
