Bitcoin is a decentralized digital currency that operates without a central bank, relying instead on a global network of computers that validate and record transactions on a public ledger called the blockchain. It was introduced in 2009 by the pseudonymous creator Satoshi Nakamoto as a peer-to-peer electronic cash system, enabling anyone to send value directly without intermediaries. Bitcoin’s supply is capped at 21 million coins, making it a scarce asset often compared to digital gold. Its decentralized design, predictable issuance schedule, and resistance to censorship have driven adoption by investors, technologists, and institutions seeking an alternative to traditional financial systems.

Litecoin is a decentralized cryptocurrency created in 2011 by former Google engineer Charlie Lee as a faster, lighter alternative to Bitcoin. It uses a modified version of Bitcoin’s codebase but features shorter block times—2.5 minutes instead of 10—allowing for quicker transaction confirmations. Litecoin also employs the Scrypt hashing algorithm, which was originally intended to make mining more accessible. With a maximum supply of 84 million coins, four times Bitcoin’s limit, Litecoin is often viewed as a complementary asset to Bitcoin, serving as a testing ground for innovations like SegWit and the Lightning Network before they are adopted more broadly.

Tron is a blockchain platform launched in 2017 by Justin Sun with the goal of creating a decentralized infrastructure for digital content and entertainment. It aims to allow creators to publish, store, and monetize their work without relying on centralized intermediaries such as streaming platforms or app stores. Tron uses a Delegated Proof-of-Stake (DPoS) consensus mechanism, which supports high transaction throughput and low fees, making it attractive for applications like gaming, social media, and decentralized finance (DeFi). Its native token, TRX, is used for transactions, governance, and interacting with smart contracts on the network.
