hi..
i just see lots of miners address on blockchain.info
i tried to register of eobot and kc miner but they say to pay fee and install a software on your pc.

my question..
1.cant i have that i pay the fee only and i don't need to install a s/w on my pc/laptop and keep it running all day.

suggest me any mining site in which there is no need of my pc/laptop.
i am willing to join under your ref..
please explain me in detail if i am wrong in any part.
thank you..
