Which Cryptocurrency Is More Likely to Be a Millionaire Maker? Dogecoin vs. Cardano

People keep coming back to crypto for its purported ability to make one rich overnight. The enduring tale is that a modest pile of coins bought today will swell into a life-changing fortune tomorrow. Two of the perennial crowd-pleasers in that genre are Dogecoin (CRYPTO: DOGE) and Cardano (CRYPTO: ADA).

Both have fan bases that are convinced they hold the ticket to seven-figure wealth. Yet markets, like gravity, enforce limits. Before stuffing money into either coin, investors should ask what has to happen, in cold numeric terms, for a fresh buyer of either of these assets today to become a millionaire.

The arithmetic spoils the fantasy here

Let's start with discussing the scale involved with either of these coins making anyone into a millionaire.

Dogecoin's market cap hovers near $24 billion. Cardano's is about $19 billion. Neither of these assets are in their freshman year at this point.

Suppose an investor puts $50,000 into either coin -- an unrealistic amount for many investors, and an incredibly unwise amount to allocate to either of these two cryptocurrencies. Hitting $1 million, even with that unreasonably large sum, demands a 20-fold return. And a gain of that size would push Dogecoin's market cap to roughly $500 billion, and Cardano's to about $410 billion.

For context, $500 billion is almost double that of the market cap of Ethereum (CRYPTO: ETH), a chain that has an entire decentralized finance (deFi) ecosystem, with hundreds of projects, thousands of developers, and many billions worth of investments with fiat currency.

The meme coin would need to absorb a flood of fresh capital far exceeding anything it has previously attracted, all without meaningful help from fundamentals, as it has none. Cardano's bar is slightly lower here but still implies overtaking all of its larger rivals, and it hasn't ever really threatened them meaningfully in any financial, technological, or ecosystem quality dimension as of yet.

In other words, both coins must leap several rungs up the crypto hierarchy.

Could such multiples actually occur? In theory, yes. Crypto history is full of large-scale surprises that defy reason and upend traditional investment advice, and there will be many more such instances in the future.

But in practice, every incremental dollar of inflow to either of these assets faces rising friction in the form of liquidity limits, profit-taking from earlier holders, and regulatory scrutiny once an asset nears systemically significant size.

Investors counting on another 20-fold run with either coin are thus wagering that the 2021-style speculative tide will roll in again and stay longer this time, all while it flows precisely into their meme coin of choice (Dogecoin) or their Ethereum alternative of choice (Cardano). Read that again: Even a repeat of 2021's wild crypto sector conditions isn't going to be enough to make the investors in these coins become millionaires, unless the coins are specifically favored.

There are not valid reasons to believe in either of them being favored in that way.

So these two coins aren't millionaire makers any more.

There's still a coin with an edge here

Despite the above, there's still a coin here that has better odds of delivering good growth to its investors -- though its odds are still not great on that front either. Assets with robust use cases can, over time, justify bigger caps, whereas those running on memes alone often stall once the joke gets old.

Dogecoin remains almost entirely meme-driven. Its chain has no smart contract capabilities, limiting practical adoption. A coin with minimal functionality must rely on continuous enthusiasm to justify price, and there's just not much reason to be enthusiastic about it.

Cardano, in contrast, has some technology in development that's on its side, at least on paper.

Development activity trackers consistently rank Cardano among the busiest projects in 2025. New governance upgrades and side-chains like Hydra promise higher throughput, and the recent Chang hard fork pushes decision-making squarely into holders' hands. Some people will likely buy the coin as a result of these developments.

But real traction is another matter. Total value locked (TVL) across Cardano's DeFi protocols sits below $350 million, with its largest decentralized exchange (DEX), Minswap, holding just $68 million, a piddling sum.

While Cardano's robust research and development ethos gives it a sturdier long-term story than Dogecoin's mascot-powered vibe, its competitive position remains very weak, and there is not any obvious reason to expect that to change right now. Without a sizable user base generating fees or a breakout application demanding Cardano, sustained 20-fold appreciation looks extremely ambitious.

Therefore, if forced to pick a "winner" for millionaire-maker potential in this head-to-head, Cardano wins on fundamentals, modest though they are.

Yet calling it a likely millionaire maker stretches credulity. Investors hunting for life-altering upside may find better odds in smaller, earlier-stage projects or, better still, in a diversified portfolio held with a lot of patience.
