It's rather simple really,
If the people renting out their miners to nicehash could make more money by solo or pool mining, they would do so... They rent out their hashrate because they're getting more money from people that rent their ASIC time, than they would get if they would mine directly. So if YOU rent their hashrate, you'll mine less coins than your renting price.
Does that mean there is no way of making a profit? Not really, but in order to make a profit by renting hashrate at sites like nicehash, you'll have to investigate and mine coins that currently have a low diff, but have a potential to rise in the future. A second way of make a little profit is constantly monitoring all prices, and buy when, for some reason, the price dips for a couple of minutes.
By just renting hashrate at nicehash and pointing it to BTC, LTC, DASH,... you'll probably lose money.
Very well explained and i do agree on such thing.If you are really wise enough you will really target those altcoins which do have lower mining difficulty and with this way this would somehow give you the chance to be profitable but if you do stick on those Giants like BTC,LTC,ETH,DASH which do have enormous mining difficulty then its expected profits would really be lesser.This is why i dont really tend to rent any hashpower because i put always to my mind that its better to have my own physical miner than on renting on others hashes.
