After Sirius get in one exchange I believe it will boost the popularity more.
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.
you conveniently missed the loads of library and api code that has been added in the last few days:
https://github.com/siriuscore/
This is a 100% copy of the bitcoin source code, just replacing the name. 2 minutes work with a global string replacement in the code.
Original repository:
https://github.com/bitpay/bitcoind-rpc
Sirius repository:
https://github.com/siriuscore/siriusd-rpc
The only thing they REMOVED is the copyright line "Copyright 2013-2014 BitPay, Inc." at the bottom, which is even illegal.
So you are right, they did do at least "something", it is not completely dead, still twitching a bit.
