In my opinion, it is definitely one of the stronger altcoins with a real project and infrastructure behind it. However, to be honest, I would not buy more.
you said that this project was a strong project but you are unwilling to buy this coin. That means if you were not seeing something good from this project. that makes you avoid to buy this coin as a part of your portfolios. It can be said that if this blockchain is bad enough to be considered as your portfolio. it's better to give honest review regarding this project. This one is actually overrated.
