Look at this statement below
Study case: I bough a 1 year contract for 1MH/s ETH mining. I've paid 0.11BTC for it (equivalent of 45$ at the time). In one year, Genesis gave me back 2.38ETH (equivalent of 69$ now), so you could say that I've made a profit. But you would be wrong!!! That's just because the price of ETH is high now (29$ versus 12.5$ one year ago).
If I would have kept my 0.11BTC, now it would be worth 135$.
If I would have bought ETH with the 0.11BTC back then (I would have gotten 3.66ETH, that's 1.3ETH more than what they gave me back), now it would be worth 106$.
Could mining is a scam! Works only for the cloud owners!
go here for more review about cloud mining site from users :
https://www.cryptocompare.com/mining/genesis-mining/bitcoin-gold-mining-contract-lifetime-small/Buying cloud mining contracts in my opinion is a bad idea,
because you will get profit if the price keep increasing and the difficulty fixed(not increasing).
but it's impossible for difficulty to not keep increasing due to demand of the users.
which mean you will get less than before everydays/months/years later.
and if you buy a contracts in there and it's no longer profitable because of the expanses that you need to buy.
they will close your account without permission.
some of them complained about their account closed by the site,you can find it in there .
how about renting the hash if you keep insisting to mine ?
you can get more than buying the contracts in cloud mining site,
rent 24 hours hash power and mine the coin that you want to mine and use the calculator.
i believe you will get more than buying the contracts,
