The last  PTK update  on their tech accomplishments was June 21, 2018..  I follow anonther venture exchange company that since June 18  has put out 25 NR s regarding  their progress ,, mind you ,,it has not helped the share price ,, but they do try to keep their shareholders updated .. I am sure they are just as busy as PTK.. This is just an example but shareholders do like to be kept updated on their company`s progress in my humble opinion..
