Profit-taking, in other words.

I first encountered Bitcoin in 2011 but choked because I got skeered about keystroke malware. (Even if I had set up a cold wallet, I still needed to heat it up to sell or transfer any BTC.) Of course, I've had the "I woulda been a multimillionaire" fantasies....

But I know that they're fantasies because I was too quick on the sell trigger (in the stock market) back then: too much of a "bird in the hand" guy at that time. If I had taken the plunge in '11, I most likely would have sold out when I could've banked a double and got left behind. So I know the "BTC millionaire" fantasy is precisely that.

Fact is, it takes some - well, stubbornness - to HODL for the long term. Some people have that, but many don't. I had to learn it the hard way.

But once you do learn it, you can look at the current price & either yawn or look for a buying opportunity. And let the profit-takers take their profits.
