I like mining crypto, but with my i5-6500 intel cpu, and a nividia 960 graphics card it doesn't really make sense. But I tried out CryptoTab browser. It uses cpu power and mines crypto, but this is actually effective. When you activate mining you can increase it by using the browser. Let's say I'm going to watch youtube for 2 hours, I'll actually get more watching on CrytpoTab than mining on Minergate or other services and using a normal browser. It's worth a try.
