Expected difficulty
This site shows incorrect information, do not trust it. On the next adjustment difficulty will not go down 16%, it will go up about 13-14%. Do you own calculations, calculate average block time manually from https://blockchain.info/blocks.
Expect at least 10% difficulty increase on each adjustment (on average), I would say 12-13% on each adjustment even more realistic.
Is it even worth it to buy hash power from cloud mining sites such as this one right now?
I don't see a point since hashpower is so low while your bitcoin value is so high.
Maybe when it was worth half as much two months ago and have it rise since then.
But not now.

It makes no sense to buy hashpower on most of the cloud mining sites. When 1 TH/s price is 400-500-900 dollars it is way too overpriced and just will not pay out in BTC (so you invest for example 0.5 BTC and get 0.25 BTC back, awesome, isn't it?). The price at Hashflare is $150 per 1 TH/s that will pay out and technically can bring some profit, but Hashflare is just not paying.
I believe they are going to scam people.
