Is it cloud mining profitable? Let's investigate what services are proposed now.
I consider 5 cryptocurrencies: Bitcoin, Litecoin, Ethereum, DASH and ZCash. Coins exchange average rates from coinmarketcap API at July 16, 2017:
$ ./mine2.py
BTC_USD: 1893 USD
ETH: 0.0768 BTC
BTC: 1.0 BTC
DASH: 0.0652 BTC
LTC: 0.02001 BTC
ZEC: 0.07936 BTC
Cloud mining proposal consists of the mining cost and maintenance fee for offered hash rate power. I've took the mining price list from Hashflare and Genesis-mining:

The calculation results sorted by annual percent from investment:

So, the most profitable is LTC mining with return of investment in about 7 month from now (July 16, 2017).
Below is shown calculation graph examples (June 30, 2017) for 100 USD investment for each of considerate currency. The "outcome" line presents our expenses growth per day from 100 USD initial payment for hash rate power. Our revenue presented by "income" line. The "profit" line is the difference between "income" and "outcome". Since the cost for mined coins are higher than maintenance fee, the income is increasing faster that outcome. When income line cross outcome line, the profit changed to positive - it is a point of investment return.
The Ethereum mining have no maintenance fee (it is included to mining cost), but ETH contract is time limited. Important! Ethereum blockchain will probably switch from PoW to PoS algorithm till the end of 2017, so mining turned off and investment may not returned. The BTC and LTC contracts are unlimited and could continue to generate profit. Keep in mind that network mining complexity is constantly increasing and hash rate power you've bought will not cover maintenance fee in future. In that case only coins exchange rate growth could compensate your investment.
BTC return in 222 days
investing: 100 USD for 364 days
revenue: 270.4 USD
maintance: 106.2 USD
profit: 64.2 USD (64.2 %)
