Meme coins may not have any utility at all, but they're certainly a great way to make profit in the short term. The crypto market is mostly speculative, so any coin that's fueled by hype, should be able to go towards new heights at a very fast pace. It'll be up to you to take advantage of this opportunity to make as much money as possible. Those who held DOGE before 2021 got insanely rich thanks to Elon Musk's efforts to pump the cryptocurrency's price. Now that hype has faded away, Dogecoin's price is declining at a slow pace. Without someone (or something) that would pump its price, the meme coin might go back to sub $0.01 prices.
At least, Dogecoin's blockchain is alive and healthy after all of these years. Even if it goes to zero, it will still survive if there's a community backing it every step of the way. As long as you don't invest more than what you can't afford to lose, you'll have nothing to worry about. Just my opinion
