There are many criticism when it comes to SONM..but I am going to HOLD it till 2019...So for almost 1,5 years. If the project will fulfill its potential then HODLing will obviously pay me some dividends. If you'd look at their roadmap you knew that 2018 is massive for them.
Another one is Espers. Have a faith in this project and think it will survive crypto cut off (it will take place around 2019 methinks).
