I follow my own advice.
And I will demonstrate you something empyrically: on 10th, September 2010 you could have bought BTC52,361 for $5,000 (the price per 1BTC was $0.095).
One year later, that amount of BTC was worth $210k dollars. If you could afford to lose $5,000, you might have followed my advice and HOLDED. I know many who did. If you couldn't afford to lose $5,000, and as in September 2011 we were in the middle of multi-month bear market, you would have sold to secure your "amazing" profits.
Now make the calculations with the current price, and you will realize how much money you would have lost in just one year and a half for not being cold minded enough to hold onto your BTC53,361
The following statement was just empirically proven wrong in the recent past:
Seriously well put. One of the most fascinating aspects of BTC is the realization of what you just said. That was one of the main hooks for me, and I'm sure a lot of other people who have gotten into it.
