Hi @zeartul, i want to thank you for tat video. A friend and I were about to buy 2 antminer s9 but after looking at your video I start to change my mind, just had to tell my friend that the better device is double price than the S9. I will dig a little more about it because those minig converters are not really accurate sometime. We want to start a little farm here in Thailand because electricity cost is cheap and we also have a house to do it just have to make it cooler inside as the weather here is hot and humid. Big thanks ^ and follow you
