What do you mean? It is already on Cryptopia:

https://www.cryptopia.co.nz/Exchange/?market=SIRX_BTC

0 BTC trading volume in the last 24 hours, less than half launch price, last activity in Github 18 days ago:

https://github.com/siriuscore/sirius

and this was only changing 6 lines of code to add some addresses. Previous commit was 6 months ago.

The project is dead. They got their BTC for listing it on Cryptopia, keeping the rest, then dumping most of their coins, and now they are laughing their ass off when someone here writes that they will still do something, while chilling at a south sea beach.
