Bitcoin and Ethereum are the two largest cryptocurrencies, yet they are not really competitors. They were designed for different purposes, and understanding that difference is the foundation of a sensible view of the market.
Bitcoin: digital scarcity
Bitcoin was created as a peer-to-peer form of money with a fixed maximum supply of 21 million coins. New coins are issued through proof of work mining, and issuance is cut roughly every four years at an event called the halving. The result is a deliberately scarce asset many people treat as a long-term store of value.
Ethereum: a programmable platform
Ethereum is a blockchain built to run smart contracts — self-executing code that powers applications. It is the foundation for most of DeFi, stablecoins, and NFTs. In 2022 Ethereum moved from mining to proof of stake, cutting its energy use dramatically.

How they fit a portfolio
Because they do different things, many investors hold both. Neither is immune to sharp swings — see risk and volatility for why. TBN Express does not give financial advice; the point here is understanding, not allocation.
