What is/are these coins that you hold? let the crowd give you ideas on what we think we those coin/s that you habe right now. With my situation, I prefer to hold and if I saw an entry Ill buy.
I sell if I really need to, otherwise IMO holding would be the best option if you are uncertain with deciding of between the two.
if I think I'm holding between ethereum and bitcoin everything will last a long time, because I know that the coin is a very good coin, which has a developing future
so I also believe that two coins can also add to my economy in the future.
I hold those coins especially bitcoin. We arent the two people that think these two would last a long time. They have significant and good future so good thing that you have added it on your portfolio.
You will never regret having bitcoin and ethereum as your long term investment.
