@eightcylinders- First off- thanks for having a level head and not screaming "gaw sucks! Ponzi!"
Props on the rating system, I really like it. However, I feel it doesn't place enough emphasis on profitability, and that's what we're all here for, right? Last time I heard, wasn't cex.io mining negatively?
For KNC- yeah it's definitely legit. They tend to fluff their customers over, so I don't really see cloud mining going much different. JMO.
Mining activity- True on the 'mining in due course'. When I purchased, I interpreted it as I was getting a payout from zenpool, which generated payouts from mining, renting, etc. I really think this category is up for debate based on technicalities. Also, Have you read the latest WSJ [Suspicious link removed]j.com/moneybeat/2014/12/01/bitbeat-under-fire-gaw-miners-ceo-garza-takes-on-his-critics/?KEYWORDS=paycoin) I trust WSJ as a reputable source, so I believe in the 28,000 btc address. With scrypt, can't they be mining other scrypt coins as well?
Backing- I thought is was out of ten, so my rating is 10-16ish? I feel a rating somewhere in there is appropriate.
VH- primes and zens mine(or should be at least) zenpool, which gets it's income from a variety of sources. It's an issue though.
Longevity- I bought in August 23rd, as was under the impression that zencloud had been around for a couple months.
Peer review- Members here are pretty quick to shoot stuff down. For every nay-sayer here, there is another supporter over on hashtalk. I understand why they created it- I mean what company wants the first thing their customers to hear to be "Terrible investment! Ponzi!"
For the market, anything in excess of 50mhs will take a while to sell, simply because the majority of investors aren't throwing hundreds or thousands of dollars at it. I listed a single zen a couple days ago, and it was gone in seconds(literally)
I bought in at 16/mh, so yeah, that's why I've gotten my money back. Regardless of the site, everybody has a slow roi right now.
