There's one new paradigm in play that might make Cardano (CRYPTO: ADA) a better cryptocurrency to buy than Solana (CRYPTO: SOL). It doesn't have much to do with the technology underpinning either chain, but it is something that investors should probably know about today rather than when it might start making a price impact, which could take a few years.

Let's analyze what's going on and determine whether it makes Cardano worth considering, or whether it will continue lagging behind.

The pace of ecosystem development matters

One of the most important factors supporting an investment thesis for buying a coin is whether there is a lot of activity on its chain. When projects on a chain are appealing to users because they offer an important decentralized finance (DeFi) service or other valuable capability, it attracts capital, boosting the price of the native token in the process. At the same time, if there's no compelling reason to park capital on a chain, money tends to flow elsewhere to find a return via investment, or to be used to pay for utility of some kind.

For investors, understanding the level of activity on a chain is not enough to make a sound decision. Instead, getting a sense of how much activity might increase in the future is key, as it's future usage that would drive prices up for those who invest today. There's no surefire way of determining whether a chain will be more in use in the future than it is today, but if there are a lot of interesting or valuable projects in development in the chain's ecosystem, it's a vote in favor of there being future demand.

Cardano is significantly smaller than Solana, with a market cap of $23.6 billion compared to the other coin's market cap of $74.3 billion. Therefore, with all else being equal, one would expect that the volume of ongoing software development for the projects hosted on each coin's ecosystem would be proportional to the chain's size, suggesting that Solana would have roughly 3 times as much development activity as Cardano.

It's difficult to measure how much software development activity is going on, but there are a few composite metrics that can approximately track how many times developers make substantive additions or changes to a chain's projects. One such composite metric, created by the crypto data provider Santiment, shows that Solana experienced around 464,000 ecosystem development events in the last 12 months, whereas Cardano experienced 389,900 events. So Cardano is seeing a huge amount of developer activity in its ecosystem for its size, and it isn't just a blip.

There's more than one factor that's relevant here

Experiencing more developer activity on its chain relative to Solana is not a slam dunk as far as making Cardano worth buying.

Cardano has a couple of substantial disadvantages that still make it a less appealing investment than Solana. First, it's more expensive and slower to transact on. Making a swap on Solana takes about a second and costs a fraction of a penny, whereas the same action on Cardano takes a few seconds at best and costs roughly $0.20 on average. That incentivizes more developers to develop applications on Solana over the long term.

Second, Cardano's ecosystem is nowhere near as diverse as Solana's, nor is it as vibrant today. It's nearly completely missing out on critical growth segments like artificial intelligence, as well as less-serious but still capital-attractive segments like meme coins. Other important categories, like stablecoins on the chain, are incredibly small for Cardano's size compared to the equivalent assets on Solana. So it has fewer opportunities for capital to flow in, and a weaker set of tools to accommodate users or investors interested in large transaction sizes.

Thus, while it's undeniably bullish for the chain to have a lot of development activity relative to a much larger chain, constituting a moderate-strength reason to consider making an investment, it's more than offset by the mediocre health of its ecosystem today. There isn't a strong reason to buy it over Solana.

It's possible that might change over the coming years, especially if its activity ramps up even more. But investors should be aware that such activity is only an investable factor if it's being directed toward producing real projects of value. And so far, Cardano simply isn't the home for the projects cryptocurrency investors are finding to be valuable today.

The U.S. Federal Reserve is facing heavy pressure to cut interest rates. President Donald Trump recently warned that Fed Chairman Jerome Powell's job could be at risk if he doesn't cut rates fast.

But let's set aside all the political undertones and deal-making calculations, and focus on the overarching questions: What happens to cryptocurrency prices if there is a rate cut? And which cryptocurrencies would become most attractive in a lower-rate environment?

The relationship between interest rates and crypto prices

The general rule of thumb is that rising interest rates result in lower crypto prices, while declining interest rates result in higher crypto prices. That might sound simplistic, but when rates are lower, the cost of borrowing is lower. Moreover, risky assets suddenly appear more attractive on a relative basis. That generally leads to an infusion of new money pouring into crypto.

This is the scenario that Charles Hoskinson, the co-founder of both Ethereum (CRYPTO: ETH) and Cardano (CRYPTO: ADA), now sees happening with the crypto market. In a recent podcast interview with CNBC, he laid out a scenario where lower interest rates might lead to a new speculative frenzy in crypto, helping to push Bitcoin (CRYPTO: BTC) to $250,000 by the end of the year. That's incredibly bullish but gives you an idea of the immediate impact a rate cut could have on crypto.

Historical evidence

Given that Bitcoin officially started trading in January 2009, three distinct time periods over the past 15 years could provide important clues about the link between crypto prices and interest rates.

There was the low interest-rate environment created in response to the 2008 global financial crisis; the Federal Reserve's policy of interest rate increases in 2017–2018; and the low interest-rate environment created in response to the pandemic.

If you look at these three periods, they all tell the same story: Lower interest rates help crypto, while higher interest rates hurt it.

For example, during the COVID-19 pandemic, central banks around the world slashed interest rates nearly to zero and introduced all sorts of new stimulus measures, in the hopes of reviving economic growth.

And it worked! The period from 2020-2021 resulted in a huge bull market rally for Bitcoin, as it skyrocketed in value to a (then) all-time high of $69,000 in November 2021.

It's easy to see why President Trump is now pressing so hard for interest rate cuts. If new tariffs are going to curtail future economic growth, then there needs to be some sort of stimulus to keep the economy moving. And that stimulus is cheap money.

Just keep in mind: Crypto is still a relatively new asset class, and we still really don't know how it will perform after rate cuts. History may be a guide, but it's not a precise indicator of what happens next.

Which cryptos should you buy?

Based on the above, Bitcoin appears to be the obvious beneficiary of lower interest rates. After all, didn't it skyrocket to $69,000 as soon as rates were cut in 2020?

However, don't forget about altcoins. In an environment of lower interest rates, riskier assets such as beaten-down altcoins (some of them down as much as 50% for the year) could start to look a lot more attractive on a relative basis. And that might mean we finally get the arrival of "Altcoin Season" -- the time of the year when risky altcoins explode in value and outperform Bitcoin.

All of this should highlight the importance of portfolio diversification. It still makes sense to make Bitcoin the focus of any new crypto buying in the wake of rate cuts, but now might be the time to explore new coins to diversify your portfolio.

My personal pick right now would be coins with significant exposure to the decentralized finance (DeFi) sector. That's what World Liberty Financial, the crypto company affiliated with the Trump family, appears to be loading up on now. These coins also performed very well during the 2020-2021 crypto bull market cycle, highlighted by the speculative, frothy "DeFi Summer" of 2020.

As always, remember to do your due diligence. Crypto has always been risky and volatile, and the current economy is especially dicey, with unknown consequences ahead.
