So basically you are saving if Bitcoin reaches 10,000 dollars it would be a bad idea to sell.  I disagree with that.  I am not saying sell every coin you have but it would be worth it to sell some of the coins.  What if Bitcoin stays at $240 dollars for the rest of time, and you have 10,000BTC.  It might not be a bad idea to sell some of those coins and make some actual fiat cash as well.  What if Bitcoin crashes, then the best time to sell them would be now.  There are plenty of times you should sell.
