There are lots of ways to invest.
There are lots of metrics to measure success.
I think declaring everyone who does not follow your strategy and metric a fool is flawed logic.
YMMV

I think anyone who looks at USD cost and return as the metric of success foolish. I don't know if that's how you view, but it must be because you seem certain that this was a good investment. However, I disagree. Anyone who has half a brain in their head should have refunded their order when BTC was at a local minima. Evaluating your investment in any other capacity is (IMO) a shallow attempt at convincing ones self they made the right move, when, outside the realm of emotional involvement it most certainly is/was not.
