Bitcoin Values - BTC Miner web with CPU

While using the PC and browsing other pages, we can leave 1 tab open by mining and generating satoshis with the CPU; What interested me about this, is that it is NOT necessary to invest, it is NOT trial and does NOT use 100% power as a free user, but it does so for Upgrades Levels, both CPU utilization or speed to use (in both starts with 10% to 20% power); To generate more power, obviously, you have to invest (150,000 satos are needed for Level 2).
What is generated updates it approximately every 2 minutes.

Give a 10% commission x RD

The minimum is a little high (0.35 BTC) but as I said, there is no overuse of CPU and we can leave it at the 2nd level working

Is it that what CryptoTab does?
