The year 2017 was a landmark period for the cryptocurrency market — a time of unprecedented growth, widespread public interest, and explosive price movements.

This article explores the state of the crypto market on December 31, 2017, offering a detailed look at top-performing assets, key trends, and what drove investor sentiment during one of the most dynamic periods in blockchain history.
The Dominance of Bitcoin and Major Altcoins
At the close of 2017, Bitcoin (BTC) reigned supreme, holding the top position with a market capitalization of over $237 billion** and a price of approximately **$14,156.

Bitcoin's dominance underscored its role as the foundational asset of the digital currency space. However, it was far from alone in capturing investor attention.
Ethereum and XRP: Powering the Altcoin Surge
Following Bitcoin were two major players that defined the altcoin narrative in 2017:
- Ethereum (ETH) ranked second with a market cap of $73.17 billion**, trading at **$756.73 per token. Known for enabling smart contracts and decentralized applications (dApps), Ethereum benefited heavily from the Initial Coin Offering (ICO) boom throughout the year.
- XRP (Ripple) secured third place with a staggering $89.12 billion** valuation and a price of **$2.30. Its strong weekly performance (+125.31%) highlighted growing interest in blockchain-based payment solutions for financial institutions.
These three — Bitcoin, Ethereum, and XRP — collectively represented the core pillars of market confidence at year-end.
Emerging Contenders in the Top 20
Beyond the leaders, several cryptocurrencies showed remarkable growth, reflecting diversification in use cases and investor appetite.
Bitcoin Cash and Litecoin: Forks and Payments
- Bitcoin Cash (BCH) ranked fourth with a market cap of $42.77 billion**, highlighting the ongoing debate around scalability. Priced at **$2,533, it had gained traction as a faster, lower-cost alternative to Bitcoin.
- Litecoin (LTC) came in sixth at $12.66 billion**, emphasizing its role as “digital silver” to Bitcoin’s “digital gold.” With a price of **$232.10, it remained a popular choice for everyday transactions.
Both assets benefited from their association with Bitcoin while carving out unique identities in the ecosystem.
High-Growth Performers
Some lesser-known names delivered extraordinary returns in late December:
- Nano (NANO) surged 77.26% in 24 hours and an astonishing 360.90% over seven days, ranking 18th with a market cap of nearly $2.89 billion. Its feeless, instant transaction model resonated with users frustrated by network congestion on larger blockchains.
- Verge (XVG) saw a 55.68% spike in one day, likely driven by social media hype and celebrity endorsements, though its long-term fundamentals remained debated.
These movements illustrate how sentiment and community momentum could rapidly influence prices during this speculative phase.
Notable Mentions Beyond the Top 10
While only the top 20 included full data, numerous other projects were gaining visibility:
- Chainlink (LINK) — Though not yet ranked in the top tier, Chainlink was beginning to build momentum as a decentralized oracle network.
- Zcash (ZEC) — Attracted privacy-focused investors with its zk-SNARKs technology.
- Dogecoin (DOGE) — Maintained a loyal community despite limited utility, foreshadowing its later resurgence.
- Binance Coin (BNB) — Just launched via an ICO earlier in 2017, BNB was quietly laying the foundation for future exchange-driven utility.
These tokens represented the expanding scope of blockchain innovation — from finance to identity, gaming, and decentralized storage.
Market Trends That Shaped 2017
Several macro factors contributed to the explosive growth seen at year-end:
1. The ICO Boom
Hundreds of new projects raised capital through token sales, many built on Ethereum’s platform. This led to increased demand for ETH and created a speculative frenzy around new digital assets.
2. Institutional Curiosity
Traditional financial players began exploring crypto, with futures contracts for Bitcoin launching on CME and CBOE in December 2017 — a major step toward mainstream legitimacy.
3. Retail Investor Frenzy
Media coverage, social media buzz, and fear of missing out (FOMO) drove millions of new users into exchanges worldwide.
4. Technological Experimentation
Projects like EOS, NEO, and QTUM promoted next-generation blockchain features such as delegated proof-of-stake (DPoS) and smart contract interoperability.
