Currently we have nearly 5500 cryptocurrencies on CMC

Some reasons for this variety:
- as you say: teams want to have money;
- there are many ecosystems that can apply the idea of blockchain: economy, real estate, transportation, energy, programming ...;
- competition within the same ecosystem;
If we don't say about scam projects, I think that the diversity of the market is a good signal, because competition is the foundation of continuous development
