Cloud mining actually encourages centralization. If gives the cloud mining company are larger presence and the "gift" of your purchase allows them to either build or buy their own private farm which they make a profit off of and then "offer" to you 3 months after they made their share. Rinse & repeat.

You are right. Most of the company now support cloud mining as it is a big business and can get a decent profit sometimes more. For example, if you buy 1 GHs. You will get ~1/12 of the
BTC you send every month. In annually, you will only get the
BTC you spent with a small amount of
BTC, say 0.001 . There is no profit at all, when we convert it into USD. Instead of doing that you can mine at home or trade
BTC. If you are good in trading, you will atleast get $10 as profit. A simple way in trading is buy 1
BTC when the USD/
BTC price is low( >550$ ) and you can sell it when it reaches atleast $600. Now you got $50 profit. It is a simple way. Remember, sometimes you have to wait for a few months to see the increase in USD/
BTC price but when comparing it to cloud mining, trading is more better.
