It depends on your perspective of positive. If the goal is to accumulate bitcoin and that’s all you care about it then it works great. You can mine a ton of bitcoin. But now if you hope to do it profitability (in fiat terms) will then you can possibly bankrupt yourself. Paying for power and miners will crush you unless you have another source of fiat to sustain the costs of mining.

Why I think people like Darth are LAPRers because when it comes to personal finance you need some level of fiat to sustain life. If not then you would use all of your fiat to mine and get Bitcoin.
