Thanks for the details .

Actually what you quote confirm a bit what i wrote :
if you go there  :  https://github.com/presstab
you will see that he is on a very active developpment on PIVX. but did not made any commit since more than 2 month on HyperStake, as he is the only one dev it can rize questions.
anyway, i do not want to send bad news, just looking for some insight on the project health and activity as there is so many POS projects to check now.
