I don't think NOO was/is a scam. NOO was the 1st ICO that I ever had bought into. But like any business, it's about keeping the shareholders happy!! The DEV team got their BTC, but we (the investors) are the shareholders. If a company I was invested in had a share price on a downward slide and the management team didn't share how they would raise the per share price, I would be dropping that investment like a hot potato.
I see the same thing with lots of coins, people saying, hold, hold, hold. Then a new shiny toy comes around and the coin is forgotten.
So DEVs, as our management team, what are you going to do to make my investment grow? Or are you going to leave that to the day traders?
