With so much development and things to be ready in few weeks from now price are incredibly cheaper. SONM whenever they released any update in past saw huge appreciation for their approach towards solution. If I remember well by the end of this year something will be out.
December 2017 or january 2018 they will release the testnet. 5× at least
Did they postpone the testnet release or not already? Are you sure they will deliver and keep promised dates?
