Definitely yes! Holding it had more positive implications to it market value in the longer term than on selling and falling market because the price value will fall. If many tends to sell its market tends to drop and its value is decreased, where as if we hold the number of investors are kept and more investors tend to get encourage to invest thus adding more players in the market place increasing more demand on the product or system.
Take for example the recent depression on the bitcoin market starting january this year up to late march many has sold out due to the downtrends in those months and price really went down.
I mean when you think about it, if everyone is holding during a price run up then people are going to be scared that the HODLERS can cause the market to crash at any moment. This is a problem, meaning that all of the people that were in here to profit from the long term growth could sell at any time and make a killing from it -- think about it, if all the holders sold the market would be in a state of disarray.
You have to think smart, not dumb folks.
