The cryptocurrency market in 2019 was marked by resilience and gradual maturation, with Bitcoin continuing to serve as the cornerstone of digital asset value. While hundreds of alternative coins (altcoins) emerged with innovative use cases, the collective market capitalization of all other major cryptocurrencies combined still fell short of Bitcoin’s standalone valuation. This article explores the top 30 cryptocurrencies by market cap during that pivotal year, highlighting their core functionalities, technological foundations, and roles within the broader blockchain ecosystem.
Bitcoin: The Digital Gold Standard
Market Cap: $476.8 billion USD
At the top of the list stood Bitcoin (BTC) — not just as the first cryptocurrency, but as the most dominant. Created by the pseudonymous Satoshi Nakamoto in 2009, Bitcoin introduced a decentralized peer-to-peer electronic cash system secured through cryptographic proof rather than trust in institutions. Its supply is capped at 21 million coins, generated through a process known as mining, which occurs approximately every ten minutes.
Bitcoin’s distributed ledger, maintained across a global network of nodes, ensures transaction transparency and immutability. Despite growing competition, Bitcoin remained the primary store of value in the crypto space — often compared to digital gold — anchoring investor confidence during volatile periods.

Ethereum: Powering Decentralized Applications
Market Cap: $98.1 billion USD
Coming in second was Ethereum (ETH), more than just a currency — it's a programmable blockchain platform. Launched in 2015, Ethereum enables developers to build and deploy decentralized applications (dApps) using smart contracts. Its native token, Ether, fuels the Ethereum Virtual Machine (EVM), paying for computational resources required to execute code on the network.
Ethereum laid the foundation for innovations like DeFi (decentralized finance), NFTs, and tokenized assets, making it one of the most influential blockchains beyond Bitcoin.
Ripple (XRP): Bridging Global Payments
Market Cap: $87.8 billion USD
XRP, developed by Ripple Labs, functions as a bridge currency within the Ripple payment protocol, facilitating fast and low-cost cross-border transactions. Unlike Bitcoin, XRP does not rely on mining; all 100 billion tokens were pre-mined. Gateways on the Ripple network are required to hold small amounts of XRP to prevent spam, adding utility to the token.
Its focus on institutional finance partnerships set it apart from many consumer-focused cryptocurrencies.
Litecoin: The Silver to Bitcoin’s Gold
Market Cap: $24.3 billion USD
Litecoin (LTC) was designed as a lighter, faster version of Bitcoin. Using the Scrypt hashing algorithm instead of SHA-256 made it more accessible for individual miners early on. With faster block generation (every 2.5 minutes), Litecoin offered quicker transaction confirmations while maintaining a similar security model.
It served as both a testbed for Bitcoin upgrades and a viable alternative for everyday payments.
EOS: High-Performance Blockchain Infrastructure
Market Cap: Not listed in original USD, but ranked #5
EOS aimed to solve scalability issues plaguing earlier blockchains. Developed by Dan Larimer (BM), EOS provided an operating-system-like architecture capable of supporting millions of transactions per second without charging users fees. It used a delegated proof-of-stake (DPoS) consensus mechanism, where token holders vote for block producers.
EOS enabled complex dApps with robust account management, role-based permissions, and cloud storage capabilities.
Bitcoin Cash and Bitcoin SV: Forks with a Vision
- Bitcoin Cash (BCHABC) – Market Cap: $18.6 billion CNY (~$2.7B USD)
- Bitcoin SV (BSV) – Market Cap: $7.8 billion CNY (~$1.1B USD)
Both originated from hard forks of Bitcoin, aiming to increase block sizes for greater throughput. BCH increased block size to 8MB (later 32MB), prioritizing on-chain scaling. BSV took this further, promoting massive blocks and positioning itself as a data ledger for enterprise applications.
Binance Coin (BNB): Utility in Exchange Ecosystems
Market Cap: $14.5 billion CNY (~$2.1B USD)
Originally an ERC-20 token on Ethereum, BNB was issued by Binance exchange with a fixed supply of 200 million tokens. It provided fee discounts for traders and later expanded into broader utilities across Binance’s ecosystem, including staking, payments, and launchpad participation.
Its success highlighted the growing trend of exchange-native tokens driving platform engagement.

Stablecoins: Anchoring Value in Volatile Markets
Two key stablecoins appeared in the rankings:
- Tether (USDT) – Market Cap: $13.6 billion CNY (~$1.9B USD): Pegged 1:1 to the US dollar, USDT became the go-to trading pair across exchanges due to its liquidity.
- TrueUSD (TUSD) – Market Cap: $1.4 billion CNY (~$200M USD): Distinguished by regular third-party audits and legal protections for holders, offering higher transparency than some competitors.
These stablecoins played critical roles in risk management and arbitrage within crypto markets.
Emerging Innovators Across Sectors
Other notable entries included:
- Monero (XMR) – Focused on privacy using CryptoNote protocol; untraceable transactions.
- IOTA (MIOTA) – Designed for Internet of Things (IoT); feeless microtransactions via Tangle, not blockchain.
- Zcash (ZEC) – Used zero-knowledge proofs for shielded transactions.
- Cardano (ADA) – Built on peer-reviewed research; aimed at sustainable long-term development.
- Stellar (XLM) – Founded by Jed McCaleb; focused on low-cost international remittances.
Each brought unique solutions — from privacy and scalability to interoperability and financial inclusion.

Frequently Asked Questions
Q: Why was Bitcoin so dominant in 2019?
A: Bitcoin had the longest track record, strongest network security, widest adoption, and recognition as a store of value — factors that gave it unmatched market confidence compared to newer projects.
Q: What is market capitalization in crypto?
A: It’s calculated by multiplying the current price of a cryptocurrency by its circulating supply. It helps rank projects by total value and assess relative size in the market.
Q: Are all top cryptocurrencies based on blockchain?
A: Most are, but exceptions like IOTA use alternative distributed ledger technologies such as Tangle, which doesn’t rely on blocks or miners.
Q: How do stablecoins maintain their value?
A: Fiat-backed stablecoins like USDT and TUSD hold reserves in real-world currencies (e.g., USD) to ensure each token can be redeemed at par value.
Q: What role do exchange tokens like BNB play?
A: They offer utility within their native platforms — reducing fees, enabling access to new token sales, and incentivizing user loyalty.
Q: Is it safe to invest in smaller-cap cryptocurrencies?
A: Smaller-cap coins can offer high growth potential but come with higher volatility and risk. Diversification and thorough research are essential before investing.
