When it comes to high-value digital assets, many assume Bitcoin (BTC) sits unchallenged at the top. However, the cryptocurrency landscape is far more nuanced than that. While BTC remains the most recognized and widely adopted digital currency, several lesser-known tokens actually surpass it in price per unit — some by a significant margin.
Based on real-time data from CoinMarketCap as of August 17, 2019, at 9:00 PM, here are the six most expensive cryptocurrencies in the world. You might be surprised to learn that Bitcoin doesn’t even make it to the top four.
1. Project-X (Nanox) — $25,606.30
Core Keyword: high-value cryptocurrency
Project-X, also known as Nanox (NANOX), stands as the most expensive cryptocurrency by price per coin. With a staggering value of over $25,600, it far outpaces even Bitcoin in nominal terms.
Nanox is a decentralized, open-source digital currency designed to offer both transaction transparency and user privacy. While transaction records are stored on a public blockchain, details such as sender, receiver, and transaction amount remain fully encrypted and private.
One of the most distinctive features of Nanox is that it is not mineable. Unlike Bitcoin or Ethereum, new coins cannot be generated through computational work. Instead, only a tiny supply circulates — just 0.078624 NANOX — making it extremely scarce and highly volatile.
To purchase Nanox, users must first convert their funds into Bitcoin, Ethereum, or Litecoin, then transfer them to an exchange that supports NANOX trading pairs. This complex process adds to its exclusivity.
At its peak on December 25, 2017, Nanox reached an astonishing $2.45 million per coin, briefly becoming one of the most talked-about anomalies in crypto history.

2. 42-Coin (42) — $22,109.96
Another ultra-rare cryptocurrency is 42-Coin, named after the "Answer to the Ultimate Question of Life" from The Hitchhiker’s Guide to the Galaxy. True to its theme, only 42 coins exist in total.
This extreme scarcity directly drives its high market price. Each coin represents a fractional share of a deliberately limited digital asset class — one of the rarest in existence.
42-Coin uses a hybrid consensus mechanism combining Proof-of-Work (PoW) and Proof-of-Stake (PoS) for transaction validation. It also includes built-in protections against 51% attacks, enhancing network security despite its small size.
All 42 coins have already been mined and fairly distributed among early miners. However, the project faced a crisis shortly after launch when a GitHub user attempted to remove the supply cap. The community quickly intervened, restoring the original limit and reinforcing trust in its scarcity model.
The combination of narrative appeal, technical safeguards, and absolute scarcity makes 42-Coin a fascinating case study in digital value creation.
3. Bitcoin BEP2 (BTCB) — $10,393.87
Core Keywords: Bitcoin BEP2, wrapped tokens, Binance Chain
Bitcoin BEP2 (BTCB) is a tokenized version of Bitcoin issued on the Binance Chain. Each BTCB token is fully backed by one actual Bitcoin held in reserve, ensuring a 1:1 peg.
Unlike native Bitcoin, BTCB operates within Binance’s decentralized exchange (DEX) ecosystem, allowing traders to access Bitcoin liquidity without relying on external wallets or networks.
The reserves backing BTCB are publicly auditable via a designated address, adding transparency to an otherwise centralized model. While BTCB offers ease of use and fast settlement on Binance DEX, its reliance on a centralized custodial system raises questions about decentralization.
Still, BTCB plays a crucial role in bridging traditional crypto assets with new blockchain platforms — a growing trend in cross-chain interoperability.
4. Wrapped Bitcoin (WBTC) — $10,352.71
Wrapped Bitcoin (WBTC) brings Bitcoin’s value onto the Ethereum network, enabling BTC holders to participate in DeFi applications like lending, yield farming, and decentralized exchanges.
Each WBTC token is backed by exactly one Bitcoin held in custody by a network of merchants and custodians. The system operates under a "consortium governance model", which means control is shared among multiple trusted entities rather than being fully decentralized.
While this introduces some centralization risks, WBTC has become one of the most widely adopted wrapped assets in Ethereum’s ecosystem due to its reliability and integration with major DeFi protocols.
WBTC exemplifies how legacy assets can gain new utility through tokenization — a key innovation driving the next phase of blockchain adoption.

5. Bitcoin (BTC) — $10,345.62
Core Keywords: Bitcoin, cryptocurrency price, blockchain technology
Despite ranking fifth in price per unit, Bitcoin remains the king of cryptocurrencies by market capitalization, recognition, and influence.
Launched in 2009 by Satoshi Nakamoto, Bitcoin pioneered the concept of a decentralized digital currency using peer-to-peer networking and blockchain technology. Transactions are recorded on a public ledger without the need for intermediaries like banks or governments.
With a hard cap of 21 million coins, Bitcoin’s scarcity is mathematically enforced. New coins are released through mining — a competitive process that secures the network and verifies transactions.
While its price per coin trails behind several niche tokens, Bitcoin dominates in terms of liquidity, adoption, and investor confidence. It continues to serve as the benchmark against which all other cryptocurrencies are measured.
6. RSK Smart Bitcoin (RBTC) — $10,341.60
RSK Smart Bitcoin (RBTC) is the native currency of the RSK (Rootstock) network, a sidechain linked to Bitcoin that enables smart contract functionality.
By locking BTC into a multi-signature address on the RSK-protected Bitcoin blockchain, users receive an equivalent amount of RBTC on the RSK network. This allows Bitcoin holders to engage with decentralized applications (dApps) while maintaining security backed by Bitcoin’s hash power.
RSK uses the same SHA-256d mining algorithm as Bitcoin and aims to become the most secure smart contract platform by leveraging Bitcoin’s existing infrastructure.
Though functionally similar to Ethereum in supporting dApps and DeFi projects, RBTC remains tightly coupled with Bitcoin’s ecosystem — offering innovation without sacrificing decentralization.
Honorable Mention: Maya-Preferred 223 (MAPR)
MAPR peaked at over **$20,600** on August 4 before crashing to under $300 within a single day — a dramatic reminder of crypto’s volatility.
Originally promoted as an asset-backed stablecoin tied to silver and gold mines in Mexico, MAPR claims to increase its underlying value every 90 days by acquiring new mining assets. Despite its listing on CoinMarketCap and ambitious goals, its price instability calls its "stablecoin" label into question.
Currently trading around $242.21, MAPR serves as a cautionary tale about speculative assets lacking proven track records.
Frequently Asked Questions (FAQ)
Q: Why is Bitcoin not the most expensive cryptocurrency?
A: Price per coin doesn’t reflect overall value or utility. Some tokens have artificially low supplies, inflating their per-unit cost despite low market caps.
Q: What makes Project-X so expensive?
A: Extreme scarcity — less than 0.08 coins in circulation — combined with historical speculation during the 2017 bull run.
Q: Are wrapped tokens like WBTC safe to use?
A: They’re widely used but rely on custodians. Trust is distributed among a consortium, not fully decentralized.
Q: Can I mine 42-Coin today?
A: No. All 42 coins have already been mined and distributed.
Q: What’s the difference between BTCB and WBTC?
A: BTCB runs on Binance Chain for DEX trading; WBTC operates on Ethereum for DeFi use cases.
Q: Is MAPR truly a stablecoin?
A: Not currently. Its extreme volatility contradicts stability claims, suggesting it functions more as a speculative asset.
