The situation is drastically changed since my last report two month ago. Now the BTC is the only currency from considered cloud mining services with ROI less then 1 year.
Bitcoin just punched 7000$ level! At same time Bitcoin mining difficulty increased more then 4x from 2017 beginning:
Difficulty
Coins mining at current difficulty level:
Coins: # 2017-11-01
BTC: 0.00000173 # coins per day for 10GH/s
LTC: 0.00046488 # per 1 MH/s
ETH: 0.000017555 # per 100 KH/s
DASH: 0.00000262 # per 1 MH/s
ZEC: 0.00000176 # per 0.1 H/s
XMR: 0.00118151 # per 60 H/s
Genesis-Mining (GM) currently propose only ETH, ZEC and XMR contacts, other currencies are out of stock. Hashing24 is sold out. Please be aware that Hashflare (HF) had voluntary changed BTC contract rules from Sept. 1 and will terminate already sold lifetime contracts in 1 year. I wrote about it in my previous post.

All other coins cloud mining contracts except BTC will not return investments in one year at the same price level. Investment in BTC (SHA-256) contract will return in about 6 months and 1 year profit makes up 109%:
BTC-HF: # return in 5.8 monthes
investing: 100 # USD for 364 days
income: 294.3 # USD
maintenance: 84.9 # USD
profit: 109.4 # USD (109.4 %)
The calculation was done with assumption of constant price and difficulty level. This is just my personal research and not an investment advise.
