What do you think are the advantages and key differences? Is NiceHash a better option for those just starting out in mining? Do you think experienced miners might ditch their physical farms to just buy a ton of EH/s on NiceHash? And how does the tax work in this case? Do they handle it, or is it on you?
Why buying hash rate for mining? If you are capable of having a physical farm, why not go for it? Having a mining farm is better. If you have enough amount of money to have a mining farm, it is better and you can get it to the point of having a mining pool. If you do not have enough to set up a farm, just buy one or two miners or have a mining rig and join a mining pool.
