$0.03 is the price they claimed and yes it's quite cheap. Generally speaking if you compare the price of electricity in KZK with others countries you will realize that there electricity is not expensive. This is their advantage.
About temperatures, it's arguable. It's a bit warmer than Island or Canada but it must be considered with the price of electricity they pay.
To my opinion, the price of ROCK2 tokens is maintained at a certain level....just because the team buy their own tokens below this level. So invetsors who ragequit and sell all their tokens "in one shot" are to my opinion doing a mistake.
