That is, projects that build an ecosystem around themselves and have subsidiary projects, partnerships, etc. Ecosystem projects are tied to marketing, they constantly need to maintain activity around them and as a consequence, there is some kind of active MM, at least such projects look no worse than the general crypto index.

Ecosystem projects are almost all big active blockchains - Polkadot, Solana, Atom, Near, Avax (all already very expensive). But they are also blockchain services like Graph, NFT ecosystem FLOW, Enjin. Yes in general there are a lot of ecosystem projects now, just another important point.
