No one really knows what could happen but since the team is seriously doing their job, you might be seeing your 310 SNM to be more than $1K in USD. Wait patiently and it could be one of your best buys in the world. But while you are seeing this to have a good future, why not buy more. Remember that it use to be just 0.07USD.
What is your target price for SONM tokens?
I hold a few of them but I want to wait more to see at least $1 in the exchanges. I hope it gets listed on bittrex and the trade volume gets higher there.
