No,not at all.

I'm not sure if I will register one either, norweigan taxes isn't anything like the ones you have in the states.(far higher)
If a norweigan labels his work as a hobby, he's allowed to earn up to 12k USD a year without paying taxes.

When the farm grows larger than that, the best way for me economically is to either keep the currency as bitcoins, or alternatively change the bitcoins into USD and then buy stocks for it.
The yield from the stocks only have a 20% tax on it (which is about one third of the tax i'd have to pay as a company)
