The 2017 bubble was a pretty steady ramp from $200 to $20,000. When your frame of reference is a 10,000% increase, then yes, 80-85% doesn't seem that terrible: you're still at +2,000%. Roughly adjusting for volume (you can never tell what's 'new money' vs. trading) about half of the people that bought into the last bubble are still in the green.
This past 'crash' has been downright tame. That's not some kind of swaggering nonchalance, just a very simple assessment of the history of price action. It was suspiciously orderly until last November when some old coins moved and tanked the market.
Even if you were 'new money', you'd have to be extraordinarily unlucky to actually have lost that much. Prices were only over $15k for a brief period, and buying into a white-hot market is such an absurdly greedy play that it's difficult to sympathize with such losses.
