I keep about a hundred coins as a long-term investment, but I sold a lot more a long time ago when I saw that the start-up hype was falling and the project had a long and difficult path to mass adoption, which was not a fact that would prove successful. However, the project is quite interesting and I do not lose sight of it.
Although it is long term investment but the approach of the dev team is really professional so they moving forward towards their destination. I hope one day it will surprise the whole world one day it have more big support behind it.
