Help to build up a mining farm and trade cryptocurrency

Hi I have my own miners (15 based each on 3 graphic card rx 570 and 580 4 gb). I would like to start with the beginning: -How much do you pay for electricity (usd/kW) This is a way to start optimizing your earnings. for instance i am paying in Romania 0.1 Euro per kW. -Do you have a person to mode the bios for your GPUs? Other way you will get only 60 of the cards full capacity. -Based on my experience, to change your miners software daily in accordance with the coin value it is a waste of time. What i mean is that: if you choose today to mine for ETH and tomorrow to mine for Zcash it means that you want to have monthly earnings...based on monthly trades...cos if you have mined today ETH and if you do not trade it at its peak in the same day you have lost the understanding of optimizing... To avoid such a story i suggest to spread your equipment to mine several coins and start trading the coins when it is really profitable ....not when those have encountered a growth of 2-5%...but next month when the value has increased with 10%. Get in touch with me for a more detailed chat, Thank you
