Thank you for the topic, it is very informative. I was wondering, what do you mean by 'be skeptical of unrealized profits'? Should I understand it as 'be weary of daily traders going into profit taking mode'? Or something else?

Basically, it's not a profit until you've sold and the fiat is in your pocket
It's just a reminder to keep a clear head when the markets appear to be going crazy and avoid greed.
