A good project is one that grows during a bear market. what do you think is this fact or just a coincidence?

some time ago I observed several projects, one of which was DOT, Solana, Uniswap, Polygon, and many more. I see that there are some similarities between the projects. their averages are released after the 2017 market crash or when the market is in a bear trend. those projects can survive and thrive when the market is not good enough for new projects. and when the market enters a bull trend, projects that develop during a bear market experience a very large increase. for example solana which goes up more than 100x.

Then I wonder if this is a coincidence or a fact. If it's a fact, maybe in the future I will pay attention to projects like this in the future.
