Hi Ulam or Roman,
I have great respect for people, especially when they are knowledgeable, in your case unfortunately I am struggling.
First of all, as you did, you should start your own thread. I do not want to be mixed up with you. I will never post in yours, not even if you had 1M replies and I had none.
In your 5 sentences post, there are more than one discrepancy.
On this post What psu for 6x (or 7) r9 fury nitro? dated March 17th 2017 you are asking help to build your own very first rig so saying you are building rigs since January is contradictory…
Also a quick glance over at your Poloniex chat history (very recent) polonibox.com it seems you haven’t much of a clue on how to get around the crypto world (asking how to exchange ZEC to GBP?!) … I wonder what kind of support and advise you give to your clients after you sell them a 48 GPU rig!!!
I welcome honest competition, I am confident of the product and service I offer but despise liars.
Get your things together and move on please.
P.
