Yeah they claim that you can earn 1BTC per day by paying them to "upgrade" your account. Looks like most of their business lies in their "Affiliate" program, which is otherwise known as a Ponzi scheme. I'd stay away from web based miners. Setting up a miner and joining a reputable pool isn't very difficult. If your problem is lack of decent hardware, no website or other software is going to be able to change that for you.
