Oh well, you live and learn! But I feel like I’ve gotten better at making decisions now that I have my wife to consult and get a second opinion. Her input really helps me think things through 
You were ahead of 99% of people setting up a mining rig . I wouldn’t sweat a mistake in hindsight . If you aren’t making mistakes, you aren’t taking risks. If you aren’t taking risks you are just a chump . Haters gonna hate . Peace
I do not have the technical skills to set up my own mining rig. The rig that I bought was already used by the original owner. All I did was follow the assembly instructions by the owner and insert my cryptocurrency wallet address. That was the reason I was only able to use it for a short time, but it was definitely fun.
