if the team are really serious about the future of this project, why they don't try to get sirius listed on one decent exchange at least, can't understand the so much slowness that revolves around this project, at one point you would think that project has been abandoned, this would definitely be of concern to any potential investor, it is not healthy in crypto to waste too much time, it leads to been forgotten 
With the current state of their project, They are developing the project in a snail pace. They are still providing update every few days via telegram group bridge but when it comes to development they are really slow. The whitepaper took 5 months to complete so the actual development will probably take longer.
As for the exchange listing, Without cryptopia there ZERO exchange for Sirx, The Dev team should start working on listing ASAP so the project wont die and forgotten.
