So even if I waited to purchase like 4 Neptunes come march, even +10TH wont be profitable?? Also are all these btc profit calculators bogus even taking into account current diff?? Its just cant understand how mining could be that hard to make a profit at, even if you had a large amount of money to initially invest.
If companies sell overpriced equipment the it's hard to make profit.
Also because in this phase the difficulty rises exponentially every miner becomes obsolete in just a few months
