Yep, that's why holding and not looking at the price everyday works great. LOL Heck, I didn't look at the price for months at a time. Probably only reason, I still have all my BTC and a little more.
Yes, But it's really difficult to not look at the prices. Everyone wants to know that who much the coins cost at any time. But you are right. In long term the price rises, but in short somethings can happen which cause the people to panic, sell their coins and miss the opportunity.
