Grin is surely still a thing.
But unfortunately, gamblers estimating projects in terms of hype and money making (or loosing) not in terms of tech innovations, though it's hard to understand for non techy people which project is truly innovative among the ocean of shitcoins and scam coins.
Grin is the only altcoin which adds something interesting to Bitcoin and complements it, without sacrificing on security or decentralization.
Grin adds enhanced privacy and more scalable blockchain comparing to Bitcoin, with the tradeoffs of interactive transactions and non auditable coin supply (though the cryptography verifies no extra coins minted).
Grin itself is innovative and doesn't need to hype around adding new "features" just to satisfy gambling behavior of the masses.
The development is still ongoing, AFAIK, the most interesting feature is mwixnet, which is going to break linkability in transactions graph and put Grin into the fully privacy coins league, competing with Monero.
But the most exciting feature of Grin coin is ONE GRIN PER SECOND FOREVER. The most fair launch, without early users advantage, same distribution rate for all no matter when you joined the network. Even Bitcoin can't compete with that. The more time past, the more Grin become valuable due to fair distribution.
I guess development for the project is still happening behind the scenes. I like GRIN because it's not an overhyped project like Ethereum and Solana. Perhaps, that's the reason why market prices haven't been rising that much lately. If the network stays alive, there would be nothing to worry about. Decentralization is all that matters for GRIN to be able to stand the test of time.
I hope GRIN stays a PoW coin forever. After all, PoW is becoming a rarity these days. We should expect further de-listings for GRIN because of its privacy features. Maybe it will end up being traded at DEXs and P2P exchanges in the long run? No one can predict the future, so lets hope for the best.
