Coinmarketcap doesnt filter these coins in their websites,these new projects/coins/tokens are automatically get listed when a certain amount of marketcap has reached,so the coinmarketcap wont list coins that doesnt have good number of marketcap,for example the starndard is $1M befre these new coins got listed,when these coins hasnt reached the $1M the project wont appear in the coinmarketcap.
