That is sad and great at the same time though - feel free to share your experience in Best and Worst Investments thread! Whilst you have missed on x24 gains since the sale, you still made a superb x17 gain on the sale day assuming you held 2011-2014. S&P500 did not even double during that timeframe so you still were exceptionally lucky.
I have always been amazed at how various analysts assure people of “this is a buy” / “the market will remain bullish” and when the worst happens, they just use ex post facto arguments to say something like “yeah, it was kind of expected based on XYZ”. Only once again proves that no one can time the market, whether we are talking about stocks or crypto.
