Yes, forgot the way using laptop to mining in this difficulty, if you mining with laptop 2 years ago, you can mining lots of bitcoins, but now, with lattop mining for 1 year, you may only get less than 0.1BTC, so just forget it.
Use CPU like I7, the hashrate is about 0.04M, now our product is 200-200G hashrate, for about 0.06 BTC this day.
You can caculate how many you can mining with computer cpu now.
Try a real bitcoin miner if you want into bitcoin mining, or just learn more before going into this risk market.
