Of course yes, once you believed in the coins you invested that means in the future you knew to yourself that it will give
you a nice profit or savings. Just make sure that the coins you choose to hold in the long term or short term has a real
potential to increase in the future, or you did a research in it before deciding to buy em.
Logically before believing with certain project you already deal with doing your research and you have a good views
with the project's potential success, either using it for your long or short term investment.
The end outcome still remain the same, you are investing becuase you believe that the project will bring you decent success.
It's more on your personal goals, the instinct inside you will lead you to work with the team for your best interest.
