This will happen in every bear market for the next decade with companies for various reasons.

Companies that overvalue "new-coins" or try to make a business out of some shiny shitcoin will go down most often.

Really good, innovative, sound strategy, large teams building things people will value 10 - 50 years from now will last. There are very few alt-coins that fit that bill. Amount of time, projects, teams and funding surrounding an alt, suggest higher value.

Anything that was a recent ICO or New Coin that didn't need to be an alt-coin is going to get rekt.

People working for those teams will also have to play the career change game, of finding similar projects like these shitcoins to earn money later OR move to high value projects with actual reason to exist. It likely gets harder to be hired by these projects the more involvement people have with shitcoins or failing projects in this space over time.

Then there are the companies that just can't manage money at all. Even with all of the right parts for a long term projects that everyone wants, theft and mismanagement of funds by so many people in the crypto space is still everywhere.

We're building money for the internet, on the internet with teams created through it as well....it's going to take some time for the dust to settle on how all of this is supposed to work well for everyone involved.
