At this point cloud mining is pretty dismal in terms of returns.  With decreasing BTC and providers trying to keep a profit at this time most cloud mining operations you can buy in low however it is uncertain if they will pull out of low returns anytime soon.

The best I heard so far is LTCGear (bitcointalk thread: https://bitcointalk.org/index.php?topic=759743.0) decent ROI and as far as I am hearing the few that people are still pretty optimistic about.   Give it some time to buy shares though (always sold out lol - can check https://ltcgearcalc.com/ they have a good automated checker if things are in stock)

No referral needed just helping a fellow miner out =P lol
