Well, you guys are not alone with that as I also do that but that was a common tactic when buying or when investing a coin. When everyone is buying, the price will rise and it can be felt during the time we buy a coin or when we are simply holding. You should not think twice buy you should sell now if your goal is to make a quick profit because when more people notice the rise, they will also sell and that results for the price to go down again.
It's true, and it's quite obvious in the market, that's why I don't always hold any coins long after I buy and always sell immediately when I see a profit, even though it's not too much profit, but profit is always very valuable to me.
Waiting for a more price hike is not easy but it can also be beneficial because the profit that your going to get this time is more than the profit that your getting when you do a short term trade. It's only a matter of self control.
Obviously, and it's not only about self-control but also a lot of patience because the pumps in the market don't happen so fast and always take a long time.
