Many of these altcoins can not be considered altcoins precisely because they are no more than shitcoins!
Then we have Bitcoin, a part in Altcoin and all the rest Shitcoin!
Shitcoin by definition are those that have no real applications or intention!
Sirius is probably in the altcoins class, with full ambition for one.
We will have to wait and see how Sirius works out, but yes, as you say the market is dominated by shitcoins and that's bad for the overall reputation of crypto.
Unfortunately this is the sad story, very minimal communication from the team but other members claims they are very active in their slack channel which i found inappropriate because here is the ann thread and equally needs to be updated from time to time.
They can quickly reply from social apps since they created a bot for them to see the message even though its a different application.
I would recommend on checking their discord and communicate with Sirius team.
