so i recieved minimum requirements (by mail):
i dont say its something expensive, but still its not what a common miner can offer in great numbers (like 30 gpu with 5 cpus .... this means i need to buy rests for 30 PCs ... or for 5 at least)
till i dont know income per day, its "a bit huge" investment
