It's easy to imagine having early awareness of cryptoassets but dismissing them as tulips when the total market value was $1m.
It's also easy to imagine not admitting the mistake after the next 10x to $10m. In fact, that explosive growth helped confirm the skeptics' thesis that it's a Ponzi about to implode.
So now that we've 10x'd five more times since then, it would be a tremendous psychological blow to capitulate now.
Those who preferred the comfort of confirmation bias to the discomfort of admitting they've been wrong all these years have paid an enormous price for that comfort.
