Browsehash is a new mining pool that's works for free, it was launched 29th of last month they have about 1500 members now, all you have to do is open the site in your browser( Chrome) laptop or mobile device input your dogecoin wallet address then select your thread, the larger your amount of thread the higher your mining speed and the more work on your CPU. So far I've seen withdrawal in blockchine but I haven't withdrawn my self. Minimum withdrawal 10dogecoin and you get 10% of every single person you refer. I'll drop my link and a screenshot below.
