Which Cryptocurrency Has More Upside? Bitcoin vs. Cardano

If you ask investors which they would rather own -- a hulking blue chip asset, or a smaller and unproven upstart -- many will prefer the latter option without thinking. After all, it's easy to fall in love with the idea of grabbing a multibagger, and it's also easy to forget how many lottery tickets inevitably expire worthless.

But is that the right lens to analyze whether it's Bitcoin (CRYPTO: BTC) or Cardano (CRYPTO: ADA) that has more upside in store for those who buy it right now? Let's investigate which of these assets is better positioned to grow and find out.

Bitcoin isn't a moonshot anymore

At this point, Bitcoin is the monetary heavyweight of crypto, and it's also a major financial asset with widespread acceptance in the traditional financial sector.

It represents more than half of total crypto market value, and it has a market cap of $1.8 trillion. Its tokenomics are brutally simple, with its supply capped at 21 million coins, and its new issuance coded to cut roughly in half every four years through the halving. Roughly 95% of that fixed cap has already been mined, so new supply is now only trickling in at the pace of molasses left outside in January (which is really slow).

The possible sources of demand for the coin have exploded since the arrival of spot Bitcoin exchange-traded funds (ETFs) in January 2024. The approval of the ETFs, long hailed as a major mark of the cryptocurrency's maturity as an asset, have made buying and holding Bitcoin available to practically every investor. But in the context of evaluating the coin's upside, it's also worth mentioning that there isn't necessarily another similarly important catalyst anywhere on the horizon.

So, in that vein, what does "upside" really mean for something this large?

A 10X move from here would imply a market cap for Bitcoin eclipsing most categories of global wealth, and approaching that of gold. That isn't impossible if investors continue to believe that Bitcoin is a store of value that's so reliable as to be "digital gold." But for the record, during the ongoing inflation flap of the last 12 months, gold's price rose 53%, and Bitcoin's price was flat, so the narrative here does not really match the price action.

Still, if you assume that institutional adoption continues and that spot ETFs keep taking up coins, a world where Bitcoin is 3X to 5X higher a decade from now is entirely plausible, and in fact fairly probable.

Cardano's potential is significant, but it's mostly theoretical

Cardano is an entirely different animal than Bitcoin, as it's a smart contract blockchain. It's also a much smaller asset, with a market cap of $17 billion.

At that scale, identically sized inflows would struggle to make Bitcoin's price move even a little, but could move Cardano's price by a lot. That's the essence of the "Cardano has more upside" argument: It's simply far less established, which implies the possibility of a big gain if that eventually starts to change.

The thing that could catalyze precisely that change is Cardano's recent move to integrate the x402 internet payment standard. The x402 protocol is a way for websites to take payments from users and display pages or data to them in return. Developers are now wiring this standard into the chain, and it might be used for AI agents to pay each other as well.

If that vision pans out, Cardano could become one of the settlement layers for autonomous software, where every model query or content request has a tiny payment attached. In theory, that's a narrative large enough to justify many multiples of upside compared with today's valuation.

In practice, implementing the x402 protocol so that Cardano's holders benefit is quite complicated. Most sites don't want to change their business models, and they probably aren't aware of the possibilities for x402 anyway, at least for now. The protocol itself provisions for payment in many different kinds of stablecoins and crypto tokens, not just Cardano, so there will be plenty of competition for whatever opportunities end up actually existing.

Nonetheless, in this match-up with Bitcoin, Cardano undeniably has more upside for those who buy it now, even if the odds of it actually realizing that upside are on the low side in comparison to Bitcoin's odds of continuing to chug along and grind upwards over time. Bitcoin is by far the safer bet, but that's also a big part of the reason why it's less likely to grow dramatically.
