Cryptocurrencies are digital assets secured by cryptography—a mathematics-based method for encoding and decoding data. These transactions are recorded on a blockchain, a decentralized digital ledger that verifies and processes payments across peer-to-peer networks without centralized authority. While blockchain is widely associated with financial transactions, its applications extend to fund transfers, trade settlements, voting, identity verification, and cybersecurity.
Among thousands of cryptocurrencies, certain types stand out due to their popularity, functionality, or innovation. Below, we explore 18 prominent cryptocurrencies and their origins.
Popular Cryptocurrency Types
1. Bitcoin (BTC)
Launched in 2009 by Satoshi Nakamoto, Bitcoin pioneered decentralized payments and serves as a store of value akin to gold. Its open-source, immutable blockchain ensures transparency, with a capped supply of 21 million BTC.

2. Ethereum (ETH)
Conceived by Vitalik Buterin in 2015, Ethereum combines a computing platform with cryptocurrency. Its smart contracts enable decentralized applications (dApps), using ETH for transactions. Ethereum transitioned from Proof of Work (PoW) to Proof of Stake (PoS) in 2022 to enhance scalability.
3. Ethereum Classic (ETC)
A 2016 fork preserved Ethereum’s original PoW blockchain, making ETC the "original" Ethereum crypto.
4. Litecoin (LTC)
Created in 2011 as a Bitcoin fork, Litecoin offers faster transactions and is often called the first "altcoin."
5. Stellar (XLM)
This open-source payment network facilitates cross-border transactions, with Lumens (XLM) acting as intermediary tokens.
6. Zcash (ZEC)
Zcash uses zero-knowledge proofs for private transactions, allowing users to choose between shielded or transparent ledgers.
7. Chainlink (LINK)
A decentralized oracle network that connects blockchains to real-world data, enhancing interoperability.
8. Uniswap (UNI)
A leading DeFi exchange on Ethereum, Uniswap automates token swaps via smart contracts.
9. Bitcoin Cash (BCH)
Forked from Bitcoin in 2017 to address scalability, BCH prioritizes everyday usability.
10. Decentraland (MANA)
A virtual-world platform where users buy NFT-based land parcels using MANA tokens.
11. Yearn Finance (YFI)
This DeFi yield aggregator automatically allocates funds to high-interest smart contracts.
12. Maker (MKR)
Governance token for the Maker Protocol, which issues the DAI stablecoin.
13. Aave (AAVE)
A lending protocol where users earn interest by supplying crypto assets.
14. Compound (COMP)
Enables DeFi lending/borrowing via autonomous smart contracts.
15. The Graph (GRT)
Indexing protocol for querying Ethereum data, used by dApp developers.
16. Livepeer (LPT)
Decentralized video transcoding network powered by LPT tokens.
17. USD Coin (USDC)
A stablecoin pegged 1:1 to the U.S. dollar, issued by Circle.
18. Dai (DAI)
Decentralized stablecoin backed by crypto collateral, native to MakerDAO.
