While it is theoretically possible to become a millionaire by investing in Dogecoin, it is **extremely unlikely** for most people who invest modest amounts. Here’s why:

**To become a millionaire by investing in Dogecoin, two things would be needed:**

1. **A very large initial investment:** To turn a small investment into a million dollars, the price of Dogecoin would have to multiply by a huge factor.

2. **A massive and sustained price increase of Dogecoin:** While Dogecoin has experienced significant increases in the past, these have been driven mainly by social media hype and celebrity endorsements, which are inherently volatile and unpredictable.

**Consider the following points:**

* **Market capitalization:** For the price of Dogecoin to increase significantly, a massive amount of new money would need to flow into it, which would drive its market capitalization to very high, possibly unsustainable levels.

* **Inflationary supply:** Unlike Bitcoin, which has a limited supply, Dogecoin has an unlimited supply and continuously issues new coins. This inherent inflation can exert downward pressure on its price in the long term.

* **Extreme volatility:** The price of Dogecoin is extremely volatile and can drop as quickly as it rises. Many investors who tried to get rich quickly with Dogecoin have suffered significant losses.

* **Lack of fundamental utility:** Dogecoin was originally created as a joke, and while it has an active community and is used for online tipping, it lacks the underlying technology and use cases of many other cryptocurrencies.

**Examples of "Dogecoin millionaires":**

There have been stories of individuals who became millionaires with Dogecoin, but they generally invested very large amounts at early stages or benefited from massive and timely increases. These cases are rare and often involve financial risk.
