this looks really bad and reminds me a lot of the failed stack exchange Area 51 community effort by @renzokuken.
Maybe this slow decline of Grin is not tied to Grin exclusively. Lately the crypto-space as a whole is being perceived in the public discussion more and more as scam-infested and a “ponzi”-scheme.
For example see:
The whole space seems to be running on unbacked Tether. Since Grin is fair it is really hard to make money on it. Grifters and Scammers avoid it. Moonboys avoid it. Reputable Devs avoid it since its still Crypto. There may just not be that many people that are interested in Grins goals as stated in grin.mw.
Its sad, but thats the world we live in.
