Hey guys I found a miner called CryptoTab. It's a browser exactly like Google Chrome with a BTC miner. I just started mining and apparently it only uses CPU for mining. The payment threshold is at 0.00001 BTC(0.036 USD), which is quite low compared to other miners. Its average hashrate is about 350H/s. So it mines about 0.0000002 BTC every 10 minutes. You can browse the web with the miner on and it doesn't even interfere or cause your PC to lag. You can also earn extra BTC by referring others.
I didn't get any payment yet but I am nearing the threshold pretty fast so I will post an update once I get the payment.
Get the browser here: CryptoTab

UPDATE: I asked to withdraw at 0.00001 BTC and it took 12 hours to get the payment, which proves that this miner is legit and working well.
