Why I'm not surprised? In fact I don't know any cloud mining service that was actually legit and made to keep their business. At the end all users of such services lose their money.sooner or later.
That is why I always say that to keep away from cloud mining is the best decision you can make. But still there are always people who will fall for their tempting offers.
We keep on telling people not to invest into any cloud mining sites even into the oldest ones like HF and Genesis since we do already know on what would
be the possible circumstances we would faced up in the end. I didn't even expect that there are still some scammy cloud mining sites as of today yet they
had already been bust up already but still peoples greed will always be the reason for this scammers to continue to pop up.
It really doesn't matter how much we tell people such sites are scams in the end, as not everyone in crypto browses these forums unfortunately, and as you said, greed takes over people very often. It's sad that things like this happen, but they'll continue to happen for quite some time.
One feature typical of most scams besides the most obvious things most people notice on the surface include the site requiring a deposit in order to withdraw funds, something that happened in the thread linked.
