The only thing about their operation that doesn't make sense to me - from the scam perspective - is why they announced a change to the contracts. Normally, a scam site just runs with the money, rather than remaining in operation while shooting themselves in the foot. If it was just that my assumption would be - at best - that they are just really really bad at business. Maybe they sold more than they had, maybe they assumed they could get hardware in faster than they ultimate could, and then realized the only way to stay in business would be to retroactively change contracts to free them from that burden and then use increased fees to try and glide back to profitability. Playing devil's advocate, that is the most positive way I could spin this, but even that wouldn't make them trustworthy enough in my opinion because by retroactively changing contracts they broke international law and are therefore vulnerable to several lawsuits.
Before, I ranked them higher in trust because their parent company - hashcoins - makes miners. My assumption was that they used the cloud mining contracts to help ramp up production and ran the cloud mining contracts during the hardware testing phase in which case the miners they sell would have been used for a number of months and then transitioned over. However, didn't they fail to deliver on product and then converted that product to cloud mining contracts? Has anyone ever received anything physical from hashcoins at all? and if so, was it recent?
Another way to spin this is that they built the cloud mining as a way to deal with their own hardware, but were out competed in the hardware department and couldn't keep up with orders or efficiency so are stuck using the miners from other companies and are too embarrassed to admit it.
Maybe they are really good at buying when low and selling when high and have introduced delays as a way to exploit those highs and lows to try and glide further.
Whatever the explanation - scam or bad business -I don't trust them. and that's a real shame too. According to my own profitability calculator that I wrote in Java to estimate how long it would take to reach a certain daily income through automatic reinvestment I'd make way more money from them in just the time it would take to get the AntMiners in the mail, even with one year contracts, but I just can't trust them. If, for example, they didn't change contracts retroactively and only had new contracts limited and if they didn't hike fees and withdraw minimums the way they did I might still be buying rather than going through the investment in my home electrical system. (Although, the first warning sign for me was learning that they don't honor referral bonuses if they use automatic reinvestment)
Oh, and if anyone is curious, here's my calculator. It's unsigned so you have to give it permission to run if your Java is updated, but it works:
https://drive.google.com/open?id=1Efbo-Y7EL7C0vBs43fXeS8lKaO5HRgbX I only spent around 12 hours programming it a few years ago and mostly wrote it to save me time later. It's based around unlimited contracts and so doesn't account for one year contracts. If there's any interest in that I might make a version two, or rewrite in C++ with a GUI, a program that takes expired contracts into account.
and, to anyone who actually wants to experiment with it and hashflare (which I don't advise) this is how much they are currently paying per TH per day after fees (based on last payment) : 0.00013627377
