Among trading projects, there are a lot of dogs meme coins. They raise a lot because dogs meme was a trend of 2021.

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.
The quantity of new projects depends on the market.
When the cryptocurrency market rises there is a big demand for new projects that is why the quantity of new projects is big.
When the cryptocurrency market falls people stop investing in cryptocurrency and there is no demand for new projects.
