I think it's fantastic possibility to buy Sonm right now. Bittrex will list them very soon. Also the team is great. The only reason it's cheap (about ICO price) guys screwed with ICO and many investors are dumped. But they have a bright future.
It's still not cheap to me. I will wait for 3k satoshi and if it decreased to 3k satosh, I'll buy some. Then I will just wait for the Bittrex acceptance officially. The rest will be easy for such a good project.
