Another question:
Would someone mining with a $100 CPU make as many coins as someone with a $6000 ASIC? If not, where is this balance at exactly?
Excuse me ? You want balance between 100$ - 6000$ investment and risk ? It's fair, but not balanced ...
I'm not seeing what you mean. The ROI is completely different, normally your maintenance costs are completely different. The risks are completly different.
It's like being mad on early adopters of Bitcoin, that they made a huge profit, it was there for everyone, but not many took the baith, is it fair, yes, is it balanced no ...
Balance has nothing to do with investments, fairness has nothing to do with balance.
The way you see it, I think nothing can be fair. But it IS balanced!
The way you explain, I could buy 60 - 100$ CPU's and outmine a 6000$ ASIC, by 60 times rate. Is that balanced then ?
