Yes, I think it is a good coin for long-term storage. There are several of these coins in my investment portfolio, and I hope that they will bring me a good profit.
I think you are right in choosing coins to invest long-term, preferably if you are willing to invest again it is not a problem with returning to buy it at the current price because it is still very low. so it will also be able to increase the value of the portfolio a little, it is possible for the next few years if you are still able to survive by holding the coin will be able to get a big profit.
