I do completely agree with you that invest in coin only when its price is down but we do it other way around. MASS ha the potential to go up and I dont agree on the point that its a coin abonden by its team. See the daily activity of this coin, if its abandoned then we wont see such huge volume on daily basis.
Even today the volume of MASS was over 2 million usd and this is something huge. Despite the fact that price has gone down, the activity in coin is still at its peak. I am buying at this price since thats the ideal time to buy the coin.
