of course I will sell it when there is a high pump because I don't want to miss it. I don't want to hold a coin because I've done something stupid so that the coin is worthless
Actually, selling them when there is a pump of their price is a good move but you might need to have a target price of selling it because you might miss a huge profit once it go rise up more and it would be hard to keep up if you already sold it all.
And if you bought back having a target buy is a must. And i think that only 50% of the profit that you've earn and half of it is for your preference if you will buy other altcoin of for yourself reward.
