MUSE is dormant but Cob is still posting and working on it. The market capitalisation is so low now that it can really jump quickly on any kind of news (I still have my MUSE). So for me is not a fiasco but a work in progress.
Cadastral has nothing to do with Graphene chains, it's an ICO run by OpenLedger on the BitShares dentralised exchange, that's it. It was promising but I didn't invest in it.
Maybe there is less crazyness as before around ICOs, probably because so much ICOs didn't fully deliver their promises. In that aspect Peerplays as demonstrated their seriousness and profesioonalism.
