I guess I’m not missing out on a lot, am I?
Nothing more than a few bucks in BTC every week that could go towards the holdings.

I don't see anything wrong in taking part in discussions, and being able to grow your BTC stash by doing so, whether it's done only in one forum or more, after all, more opportunities = more BTC being collected. Signature campaigns aren't full-time jobs, anyway.

One important thing to note is that even in Altcoinstalks, signature campaigns still pay in BTC.
