I have a place which is pretty cheap in electricity and would have good circulation being a warehouse. The warehouse is huge and while it is used for other things there would be a dedicated area for the miners so they could run uninterrupted 24/7. The only issue is there are so many miners out there today and a lot of them are either sold out or on preorder and I am wondering what would be the best investment for a medium scale operation?
There is no "one-size-fits-all" when it comes to choosing a mining gear, it's a combination of a few factors.
1- Your power rate and voltage
2- Your budget
3- Your power and space capcitity
These are a few major factors that need to be considered, there are a few more, but you basically want to evaluate all things to make the right decision, the only common thing would be to avoid mining gears that are known to have a high failure rate, other than that, it's case-by-case.
