To date I have not found what can be done with this project, The application is still in beta stage, even though it has been quite a long time since the project was released and I didn't find anything in the telegram group either.
It died already. I participated to their campaign last 2018 and I thought they have some plans after it.
The only exchange listed STU is yobit, there is nothing to this project anymore. It could have been better if they just show small improvement at least then maybe they can attract investors while there is bullrun.
