It's possible, but highly unlikely. The vast majority of people investing in meme coins lose money, or make modest profits that are nowhere near life-changing amounts. While a few early adopters of specific coins have seen ridiculous gains, they are outliers of an exceptionally risky investment strategy.
If you're exploring meme coins, do so with extreme caution. Only invest what you absolutely can afford to lose, do your research, and never let the potential for "becoming a millionaire" cloud your judgment.
