Trust me don't even try to ask for facts. I asked for equipment they use or a verification from a manufacture and he each time does not anwser but tries to say something bad about me. I still want to see equipment verification that is more important to me then a weekly payout as a payout really does not show it was mined and not ponzi. But I have given up with him. Chances are he will attack you and even me for posting this in a post.
There are legit sites. I as always suggest for people to research any investment especially cloud mining. You should not be pushed into buying. But do some research find a company you feel comfortable with. Then after that work on ROI see if it's a fit for you.
Seems shady, a ponzi scheme doesnt have to be a 2-3 month duration adventure with 500% daily gains.
It can be a 50 year old scheme with 2% gains/month. Ask Madoff, he knows how to operate one for 30+ years

Now I`m not saying they are a ponzi, but it certainly raises suspicion.
I feel I have been pretty nice on it I never attacked his company or him. I just asked for proof of the mining equipment. That has got me on his mad radar ever since. So at this point I just avoid. I still would like to see mining gear if they want to say they are legit.
My main thing is like I said I push people to research. I make 0 money off of what people decide on cloud mining. So I don't push, just tell them to research before doing investment.
