I always check coinmarketcap.com every day and all trending projects.
Among trading projects, there are a lot of dogs meme coins. They raise a lot because dogs meme was a trend of 2021.
But maybe in 2022 the trend will become a cats meme coins likes this

Because there are a lot of new projects the competition between them is very high.
In such a situation only the best projects will survive that is really useful for people and that will continue their development even in the fall of the market.
It will be a lot of new projects if the market will raise and it will be a big demand for them.
But if the market will fall it will not be so many new projects because it will be no demand for them.
