But I have just found https://goo.gl/nmFzQa - it is FREE while allows you to do mining and got 10 level deep referral systems, so do you think this is worthy? And is it not better than mining by our self?
Will love to hear people’s view!
It's a Google Chrome extension which you have referred. It may connect your PC to the mining pool and use you PC power to mine bitcoin and if it still gives you the 100% of the BTC mined from your computer power then you will not be in any kind of profit.
My advice is just stay away from those kind of extension else it will secretly use you pc power without rewarding you. If you want to mine then start it professionally.
