For real? A DOGE ETF? I've thought institutional investors took things seriously. I guess I was wrong. It seems that both retail and institutional investors prefer highly-risky and speculative assets on top of everything else. I'm sure there will be a "meme" coins frenzy if a DOGE spot ETF gets the green light from the SEC. I understand investors want a Dogecoin ETF because it's the oldest "meme" coin in existence. But other coins might not get so lucky due to their unproven nature.
2030 is just 5 years away, so a lot can happen before then. Perhaps, PEPE, SHIBA, and the rest will survive. Or maybe they'll fade away as new coins take over their place in the market. We'll never know for sure until the time comes. To be on the safe side, just diversify into Dogecoin and Bitcoin. Only invest what you can afford to lose. Nothing is guaranteed to be 100% safe, so better have a plan/strategy to avoid undesired situations in the long run.
Investors and institutions from Wall Street are only interested in profits, nothing more. If the Doge ETF is approved, I believe many other memes will also apply for ETFs and many of them will be approved if ETFs Doge successful.
Before the Doge ETFs were filed, the Doge ETP was also officially approved and operating in Europe. ETPs work similarly to ETFs but belong to the European market.
Also, not just Doge, there are rumors that the Floki ETP has been approved and will be trading soon this year. So in my opinion if altcoins like ETH, XRP, BNB can survive for years to come then there is no reason why OG memes like pepe, shiba or floki will disappear in the next 5 years.
