not sure the market is saturated - i think a lot of cryptocurrencies on coinmarketcap are shitcoins, and a lot of nice (and not nice) defi tokens are coming to the market and transforming everything
No, you have to understand that although De-Fi projects are increasing in popularity but their marketcap is still way lower compared to the marketcap of bitcoin and ETH which is the most popular in altcoins market.
Look here
https://coinmarketcap.com/defi/.. the marketcap in total is only $34 Billion while bitcoin has over $500 billion and ETH with over $100 billion.
See the difference? There's really a big difference.
