Why stop DCAing into ALTs?

Trying to get my head around all the doom and gloom posts regarding ALTs.

Looking back on the last bear market, a lot of the top ALTs really didn't do much. Seems a bit like the dotcom boom in 1999 where you only needed to build a website, regardless of your core business, to get investor funds.

This time around, top ALTs, even the ALTs being attacked by the SEC look to be, for a lack of a better term, doing stuff. Many of the ALTs have continued to build/progress their roadmaps all through the boom and bust. They seem to be more business focused and have actual structure compared to coins that busted previously. They have been gaining partnerships with large non web3 corporates, and basically seem much better run.

So I'm just a bit confused why anyone already investing in one of most risky assets would feel they need to exit completely at a very large loss now compared to other large swings, or even when they "invested" in sh!tcoins like safemoon or Pepe.. Guess they believe the tokens wil alll fail? I'm a bit more hopeful for some of these larger ALTs. So will continue to DCA. Would love to hear thoughts on this.
