5 Types of Cryptocurrencies

Bitcoin is the first cryptocurrency, launched in 2009 by the pseudonymous developer Satoshi Nakamoto. It operates on a proof-of-work blockchain with a total supply capped at 21 million coins. Bitcoin is the largest cryptocurrency by market capitalisation and functions as the primary benchmark for the broader crypto market.

Litecoin was created in 2011 as a faster alternative to Bitcoin. It produces new blocks approximately every 2.5 minutes compared to Bitcoin's 10-minute block time, making it more practical for everyday payments. Its total supply is capped at 84 million coins.

Stellar is a payment network designed for cross-border transactions between different currencies. Its native coin, XLM, acts as a bridge currency that facilitates conversions between fiat currencies and other digital assets on the Stellar network. Transactions settle in three to five seconds with minimal fees.

XRP is the native coin of the XRP Ledger, a blockchain built for fast, low-cost payment settlement. It processes transactions in three to five seconds, positioning it as an alternative to traditional cross-border payment systems like SWIFT. All 100 billion XRP were pre-minted at launch rather than produced through mining.

Bitcoin Cash is a cryptocurrency that split from Bitcoin in 2017 through a process called a hard fork. The fork was triggered by a disagreement over how to handle increasing transaction volumes. It increased the block size limit to allow more transactions per block, prioritising use as a payment currency over a store of value.

Ethereum is the first and largest smart contract platform, launched in 2015 by Vitalik Buterin. It introduced programmable blockchain functionality, allowing developers to build applications directly on its network. Ethereum transitioned from proof-of-work to proof-of-stake consensus in 2022, reducing its energy consumption. ETH is the second-largest cryptocurrency by market capitalisation after Bitcoin.

Polkadot is a smart contract platform designed to connect multiple blockchains into a single interoperable network. Its core feature is a relay chain that allows independent blockchains, called parachains, to communicate and share security. DOT is used for governance, staking, and bonding parachains to the network.

Polygon is a scaling platform built to reduce transaction costs and increase throughput on Ethereum. It processes transactions on a separate network and then records them back to the Ethereum blockchain, allowing users to access Ethereum's ecosystem at lower fees. POL is the network's native coin, used for transaction fees and staking.

Tezos is a smart contract platform that uses an on-chain governance model, allowing token holders to vote directly on protocol upgrades without requiring hard forks. This self-amending mechanism is its primary differentiator. XTZ is used for staking, governance voting, and paying transaction fees on the network.

Cardano is a smart contract platform developed through peer-reviewed academic research. Its development follows a formal verification process, where protocol changes are published and reviewed before implementation. Cardano uses a proof-of-stake consensus mechanism called Ouroboros. ADA is used for staking and transaction fees on the network.

Avalanche is a smart contract platform built for high-speed transaction processing. Its architecture uses three separate chains that divide the workload of transactions, smart contract execution, and asset creation, allowing the network to handle high throughput without congestion. AVAX is used for transaction fees, staking, and governance.

Binance Coin is the native coin of the BNB Chain, a smart contract platform created by the cryptocurrency exchange Binance. Beyond powering dApps and DeFi protocols on BNB Chain, BNB is also used to pay trading fees on the Binance exchange at a discount. This dual utility across both a blockchain platform and a major exchange distinguishes it from other smart contract coins.

Kusama is an experimental smart contract platform that serves as a testing environment for Polkadot. New features and parachains are deployed on Kusama first before being released on Polkadot's main network. It operates with faster governance and lower barriers for validators, making it suited for early-stage projects. KSM is used for staking, governance, and parachain bonding.

Solana is a smart contract platform built for speed. It uses a combination of proof-of-stake and a mechanism called proof-of-history, which timestamps transactions before they enter the consensus process. This allows Solana to process thousands of transactions per second with low fees. SOL is used for transaction fees and staking on the network.

Glimmer is the native coin of Moonbeam, a smart contract platform built as a parachain on Polkadot. Moonbeam is designed to be fully compatible with Ethereum, allowing developers to deploy existing Ethereum applications on Polkadot with minimal changes to their code. GLMR is used for transaction fees, staking, and governance on the Moonbeam network.

Tether is the largest stablecoin by market capitalisation and the most widely traded cryptocurrency by daily volume. Each USDT token is pegged to the US dollar and backed by reserves held by Tether Limited, which publishes regular attestation reports on its holdings. USDT is available on multiple blockchains, including Ethereum and Tron, and serves as the primary trading pair on most cryptocurrency exchanges.

USD Coin is a stablecoin pegged to the US dollar, issued by Circle. Each USDC token is backed by cash and short-term US Treasury reserves, with monthly attestation reports published by an independent accounting firm. USDC is widely used in DeFi protocols and is considered a more transparently audited alternative to USDT.

Chainlink is a decentralized oracle network that connects blockchain smart contracts to real-world data. Smart contracts operate in a closed environment and cannot natively access external information such as price feeds, weather data, or API responses. Chainlink solves this by providing a network of independent nodes that deliver verified off-chain data to on-chain contracts. LINK is used to pay node operators for their data retrieval services.

Uniswap is a decentralized exchange protocol built on Ethereum that allows users to trade cryptocurrencies directly from their wallets without an intermediary. It uses an automated market maker model, where liquidity is supplied by users who deposit token pairs into pools rather than relying on a traditional order book. UNI is the protocol's governance token, giving holders voting rights on proposals that affect the platform's development and fee structure.

Compound is a decentralized lending protocol built on Ethereum that allows users to lend and borrow cryptocurrencies. Lenders deposit assets into liquidity pools and earn interest, while borrowers provide collateral to take out loans. COMP is the protocol's governance token, granting holders the ability to propose and vote on changes to the protocol's parameters, including interest rate models and supported assets.

Quant is a blockchain interoperability project focused on connecting distributed ledger technologies with existing enterprise systems. Its core product, Overledger, is a gateway that allows businesses and developers to build applications across multiple blockchains without running their own nodes. QNT is required to access and use the Overledger platform, functioning as a licence key for the network's services.

Dogecoin was created in 2013 as a parody of Bitcoin, using the Shiba Inu "Doge" meme as its branding. Despite its origins as a joke, Dogecoin developed a large community and gained significant market capitalisation, partly driven by endorsements from public figures including Elon Musk. Dogecoin operates on its own proof-of-work blockchain with no supply cap, meaning new coins are mined continuously.

TRUMP is a memecoin launched on the Solana blockchain, branded around former US President Donald Trump. It gained rapid attention and trading volume following its launch, driven by political sentiment and media coverage. Like most memecoins, TRUMP has no underlying protocol utility and derives its market value from speculative demand and cultural relevance.
