Well that may be true, I'm not a professional nicer and i can tel you that i won't know what to do with my equipment if i had it deliver to me. but i can tel you that i did make money on my contract on nimbus they where the only one who did not have more fees after you paid for your basing and they let you chose you're pool !
any way my experience was positive and i can only recommend them.
If you picked a pool that was mining a fresh pump and dump coin and you managed to sell the coin quickly you could make a profit I guess, but that is not something 95% of people could reproduce.
