There is.
If you go long term and don't look at the current market conditions. You'll only get hurt if you check the price from time to time and it won't go accordingly to your plan.
I think imma stick to this idea, coz i always been robbed by being so hasty in selling my coins everytime I see it drops. So its better to just look at it once a month I think, maybe a better decision.
Seeing developments too often will endanger our investment, especially like me who is always depressed when I see prices fall and want to sell soon so as not to suffer even greater losses. After all was sold then the coin crawled back up and I could only bite my fingers.
