Wanna mine some bitcoin, but have no farm? Now you don’t need it! Just install CryptoTab, the world’s first browser with built-in mining features. Fast, convenient and easy-to-use, it will mine BTC while you’re browsing the web or just keep window open and active. Check it out - CryptoTab Browser

Overview

CryptoTab Browser is a brand new Bitcoin CPU miner that allows you to mine Bitcoin while browsing. The browser looks exactly like Chrome. It will use up your CPU resources, but will only use the unused portion, so you can browse normally without anything crashing. You can also use many devices to mine at the same time to increase your profit. (Your electricity bills will slightly increase, but mining is profitable because it uses the most profitable cryptocurrency and converts them to Bitcoin.)

Mining

To start mining, drag the mining sped to the hashrate your prefer. The higher the speed, the faster the mining is, but will use more CPU resources. Your hashrate depends on the type of CPU you use and the difficulty. (I use an iMac 2019 so my hashrate is about 300-500 per second.) Keep in mind that your antivirus software may block the miner, so you will need to whitelist the miner. It's not a malware, just a false detection. The miner can be kept on all the time, even when you go on vacation or sleep, but you will need to lower the brightness. Every 10 minutes, your balance will update.

Withdrawal

If you manage to reach 0.00001 BTC (1,000 satoshi), you can withdraw to your wallet. (Keep in mine that it only support the "Blockchain" wallet - Blockchain Wallet. If you use another wallet, you will have to create a Blockchain Wallet and then send it to your main wallet.) When you withdraw, the system will review your withdrawal and then check the fraud. If it pass, your Bitcoin will be sent and be confirmed. The process only takes 2 days (more during network congestion due to low transaction fees used). 

There is also a payment journal to ensure that withdraws are paid, because some people think they don't pay.

Referral Program

Mining Bitcoin by yourself isn't enough to earn a good profit due to the difficulty increasing. You will have to invite some referrals if you want to have a good profit. To invite people, you can share it on social medias or copy the referral link to use in a chatroom. CryptoTab has a ton of promo materials to increase your profit. The referral earning is 15% - 10% - 5% - 3% etc. You can create more links to track earnings of each sources.
