The world of cryptocurrency is built on innovation, decentralization, and economic experimentation. One of the most fundamental aspects shaping a digital asset’s long-term value is its supply model—whether it has a limited or unlimited supply. While many believe that scarcity drives value, others argue that flexibility in supply can support utility and adoption. So, can cryptocurrency truly be unlimited? Let’s dive into the mechanics, implications, and real-world examples to understand what this means for investors and users alike.
Understanding Cryptocurrency Supply Models
Before exploring specific coins, it’s essential to define key supply-related terms:
- Circulating Supply: The number of coins currently available in the market and in public hands.
- Total Supply: All coins that have been created, including those locked, reserved, or not yet released.
- Maximum Supply: The hard cap on how many coins will ever exist.
These metrics shape investor expectations and influence price dynamics over time.

Cryptocurrencies with Limited Supply
Scarcity is a core principle behind many top cryptocurrencies. A capped supply creates digital scarcity—similar to precious metals like gold—potentially increasing value as demand grows.
Top Cryptos with Capped Supply
- Bitcoin (BTC) – The pioneer of blockchain technology, Bitcoin has a maximum supply of 21 million coins. This hard cap is hardcoded into its protocol and ensures deflationary pressure over time.
- Binance Coin (BNB) – Originally with a max supply of 200 million, Binance periodically burns tokens, reducing total supply and increasing scarcity.
- Cardano (ADA) – Features a maximum supply of 45 billion ADA, carefully managed through its proof-of-stake consensus.
- Avalanche (AVAX) – Designed with a fixed supply of 720 million AVAX, promoting long-term predictability.
- Algorand (ALGO) – Caps its supply at 10 billion ALGO, supporting stability and controlled distribution.
- Litecoin (LTC) – Often called “digital silver,” Litecoin has a 84 million coin limit—four times Bitcoin’s cap.
- XRP (XRP) – Though not mined, XRP has a total supply of 100 billion, all pre-created at launch.
These projects rely on predictable issuance schedules and scarcity to build trust and long-term investment appeal.
What Happens When a Cryptocurrency Reaches Max Supply?
Once a cryptocurrency hits its maximum supply, no new coins can be mined, minted, or otherwise generated. For example:
- Bitcoin is expected to reach its 21 million cap around the year 2140. After that, miners will rely solely on transaction fees for rewards.
- This shift could impact network security and transaction economics but also reinforces Bitcoin’s status as a deflationary asset.
With no new supply entering the market, price movements become more sensitive to demand fluctuations, investor sentiment, and macroeconomic factors.
Is Ethereum’s Supply Unlimited?
Unlike Bitcoin, Ethereum does not have a maximum supply cap, making its model fundamentally different. However, it’s not entirely inflationary due to its unique monetary policy.
Ethereum introduced the EIP-1559 upgrade, which burns a portion of transaction fees—often leading to net deflation during periods of high network usage. In fact, there have been times when more ETH was burned than issued, resulting in a decrease in circulating supply.
Additionally, Ethereum has an annual issuance cap of approximately 18 million ETH, but this is more of a guideline than a strict rule. The combination of staking rewards and fee burning creates a dynamic, adaptive supply system focused on sustainability rather than artificial scarcity.
This hybrid approach positions Ethereum as a utility-driven blockchain where supply responds to demand—a stark contrast to rigidly capped assets.
Are There Cryptocurrencies with Unlimited Supply?
Yes—some major cryptocurrencies operate without a maximum supply cap.
Examples of Unlimited Supply Cryptos
- Dogecoin (DOGE) – Originally created as a joke, Dogecoin has no supply cap. It currently mints around 10,000 new DOGE per minute, leading to ongoing inflation.
- Shiba Inu (SHIB) – Despite having 1 quadrillion tokens initially created, SHIB does not have a hard cap. While massive burns have occurred, future issuance remains possible depending on protocol decisions.
Coins with unlimited supplies often face skepticism due to inflationary risks. Over time, constant new issuance can dilute value unless matched by equally strong demand growth.

Which Cryptocurrency Has the Highest Circulating Supply?
As of 2025, the leaders in circulating supply include:
- Tether (USDT) – With over 76 billion USDT in circulation, it dominates as the largest stablecoin by supply.
- Ethereum (ETH) – Over 118 million ETH are currently circulating.
- BNB (Binance Coin) – Around 166 million BNB in circulation (pre-burn data).
- Bitcoin (BTC) – Approximately 18.9 million BTC mined so far.
While high circulating supply doesn’t necessarily indicate higher value, it often reflects widespread use, liquidity, and ecosystem maturity.
Why Cap the Supply of Cryptocurrency?
Capping supply serves several strategic purposes:
- Prevents Inflation – Without limits, continuous coin creation can erode purchasing power.
- Enhances Scarcity – Artificial scarcity mimics gold and other precious assets, appealing to long-term holders.
- Builds Trust – Predictable monetary policy increases transparency and reduces manipulation risks.
- Supports HODL Mentality – Investors are more likely to hold assets they believe will appreciate due to limited availability.
However, a capped supply isn’t inherently superior. Some projects prioritize accessibility and transactional use over store-of-value functions.
Can You Buy Cryptocurrency with Unlimited Supply?
Yes—you can buy coins like Dogecoin or Shiba Inu despite their unlimited or inflationary models. But doing so requires understanding the risks:
- Inflation Risk: More coins entering circulation may reduce individual coin value.
- Speculative Nature: Many unlimited-supply tokens rely heavily on community hype rather than fundamentals.
- Long-Term Viability: Without strong utility or burn mechanisms, these assets may struggle to retain value.
That said, some unlimited-supply cryptos integrate deflationary features—like token burns—to offset inflation and create equilibrium.

Frequently Asked Questions (FAQ)
Q: Is Bitcoin’s supply really limited to 21 million?
A: Yes. Bitcoin’s protocol enforces a hard cap of 21 million BTC. This limit cannot be changed without consensus from the entire network, making it extremely secure against inflation.
Q: Does Ethereum have a maximum supply?
A: No. Ethereum does not have a maximum supply, but it implements fee-burning mechanisms that can make it deflationary under certain conditions.
Q: Why is Dogecoin’s supply unlimited?
A: Dogecoin was created as a fun, accessible cryptocurrency. Its unlimited supply encourages spending rather than hoarding, aligning with its community-driven ethos.
Q: Can a crypto with unlimited supply still be valuable?
A: Yes—if demand consistently outpaces new issuance. Utility, adoption, and tokenomics (like burns) play crucial roles in maintaining value despite inflation.
Q: What happens when a crypto reaches max supply?
A: No new coins are produced. Miners or validators are rewarded solely through transaction fees, and price dynamics depend entirely on market demand.
Q: Is circulating supply more important than maximum supply?
A: Both matter. Circulating supply affects current market price and liquidity, while maximum supply influences long-term scarcity and investment outlook.
Final Thoughts
Whether a cryptocurrency has a limited or unlimited supply significantly impacts its economic behavior and investor appeal. While capped supplies like Bitcoin’s 21 million model promote scarcity and potential appreciation, unlimited models like Ethereum or Dogecoin offer flexibility and usability at scale.
Understanding these differences empowers investors to make informed decisions based on their financial goals—be it long-term holding, active trading, or supporting innovative ecosystems. As the digital asset space evolves, both models will continue playing vital roles in shaping the future of money.
