Don't be rude please. Some of us just want some hashrate without buying some expensive ASIC miners. I think cloud mining is great way to get involved in Bitcoin mining in no time. I personally love to wait for mined mBTCs and then trade it or use it to buy another contracts, services which can be bought by Bitcoin etc. I used to reinvest every single satoshi mined by cloud mining services but I plan to use mined coins to pay for webhosting of my projects every month.. what's wrong with that? Just don't expect to get rich and be careful - don't invest too many BTCs, that's all imho.
