this coin is a scam? 
I wouldn't recommend buying this shit. They've finished the development and now don't have money? Spent 42 million in 2 years, That's a lie, SONM team used ICO funds for personal projects/company. Now without any money or marketing this shit is dead, Binance and other exchange will likely delist SNM for this behavior.People who don't have faith in this coin will not touch at the pumping stage. I don't know what was the exact news released by the team because we are seeing much negative news from the community that the admin has left the project without any developments.
if you get this news on telegram group then it could be fudding by some people.
in last 24H sonm rise about 69% according to coinmarketcap. if negetive news comes then why this is going up in one day?
According to you, there is no positive news released from the team then how the price of SNM increase more than 150% in one day. In the current fluctuations, how can a coin price increase very quickly to that much higher value?
