I'm in doubt.
I got the BTC I invested very cheap. So if I get the BTC back I've invested in the chip and 50% of the money invested in a Bitburners I would be even already because of the current BTC rate.

But like Roy, I'm actually not looking for profit, I'm just in it for fun.
I would be satisfied if I just get a ROI. And correct me if I'm wrong, but even with the rising difficulty this should be possible, right?!
