That's cool that you're doubling your farm size. Have you actually got room to do it?
Well, "hoping" to double it. Will need the loan first.
I have the room in my mining room in the house to add eleven (11) more rigs. More than that and I will have to build a shed in the back yard or lease a small warehouse. I prefer to have a shed built out back. I'm considering a 16 feet wide by 32 feet long by 17 feet high to be built in the back yard "IF" I can get a loan.
I may be forced to wait till this time next year by depending on profits made from mining and trading the remainder of this year. However, the profits I make from mining and trading this year may only be enough to replace the remaining AMD rigs I have with NVIDIA rigs "WHILE" leaving my AMD rigs off-line for a few months. Once the new year (2019) begins, I'll have to wait a few more months for profits to accumulate to build the shed out back and get a power upgrade. Again, this is WITHOUT a loan and assuming revenue/profits from mining and trading will be similar to previous years.
Then once the shed is built and power upgrade installed, I would be able to move EVERYTHING to the shed and get the AMD rigs online.
