And in the other side of the spectrum I also see people that prefer to hold their coins for a very long time and they are profitable as well, so people should not worry at all about the amount of time that they hold their coins, because as we can see you can make money by holding your coins for a very short amount of time and and also by holding them for a very long amount of time.
And I do not really have the time to do that but when it comes to long term trading as long as you can check the price once a day you're going to have enough information to take a decision to keep holding your coins or to sell them.
