I figured with the current situation its a good way to make back my investment for the hardware. Then when i make enough money for a new miner every couple of months then i can purchase new hardware and slowly build from there.

All this being said, it sounds like an S3+ wouldn't be my best investment. I don't want to invest all my savings but i figured i could really get ahead because of the free energy situation. What would you guys/gals suggest a good startup ASIC be?

I'm new to Bit Mining i want to see how profitable i would be with a small investment. I'm not looking to make a lot, but i think the situation i'm in could really help me get ahead and later on invest more money into it. I own a computer business and i don't have a electricity bill (covered by land lord) The internet fee is covered by the company and i have the technical knowledge to maintain the hardware. I can get a used AntMiner S3+ at 453Gh/s for about $150. I have 680 watt psu that can be used for the system free of charge. What do you think my profitability of this setup is?
