The $ 119 unlimited plan is monthly and I inquired three times if it's $ 119 if I use 1000kw or 20000kw and they send there's no limit.
If there is no limit then it's a bit suspicious and I feel it's a scam company. If you know it's legit then it's a good offer but I'm curious about how they generate power and why they offer unlimited power without minimum wattage or how many miners they are allowed to run at $119/month.
The fixed rate is a fair price and it is I think safe than the unlimited offer.
