MetaMask and Self-Custody Wallets
MetaMask is the most used Ethereum wallet for interacting with DeFi protocols and NFT marketplaces — understanding seed phrase security, hardware wallet integration, and not-your-keys risks is fundamental.
Ethereum is the foundation of decentralized finance and Web3 — understand the technology, use cases, and investment strategies for the world's second-largest cryptocurrency ecosystem.

MetaMask is the most used Ethereum wallet for interacting with DeFi protocols and NFT marketplaces — understanding seed phrase security, hardware wallet integration, and not-your-keys risks is fundamental.

Buying small amounts of ETH at regular intervals regardless of price removes the pressure of market timing — DCA into ETH on Coinbase, Kraken, or through institutional grade platforms reduces volatility impact.

Ethereum's transition from energy-intensive Proof of Work to Proof of Stake reduced energy consumption by 99.95% while enabling ETH staking rewards — transforming Ethereum into a yield-generating asset.

Decentralized finance protocols allow lending, borrowing, and trading cryptocurrency without banks — Uniswap's automated market maker, Aave's lending pools, and Compound's yield farming have collectively processed trillions in volume.

Ethereum is a programmable blockchain enabling smart contracts and decentralized applications — unlike Bitcoin's store-of-value focus, Ethereum is programmable money supporting DeFi, NFTs, and the emerging Web3 ecosystem.

Non-fungible tokens representing digital ownership of art, gaming assets, and collectibles primarily run on Ethereum — the NFT market peaked in 2021-2022 and continues evolving as a digital ownership infrastructure.

Arbitrum, Optimism, and Base are Ethereum Layer 2 networks processing transactions faster and cheaper than mainnet while inheriting Ethereum's security — dramatically improving DeFi accessibility for everyday users.

SEC-approved spot Ethereum ETFs allow traditional investors to gain ETH exposure through brokerage accounts without self-custody complexity — BlackRock's ETHA and Fidelity's FETH are major institutional products.

Staking ETH earns 3-5% annual yield by helping validate transactions — accessible via liquid staking protocols like Lido (stETH) or Rocket Pool (rETH) without the 32 ETH minimum for solo validation.

Smart contract code bugs, flash loan attacks, and protocol exploits have caused billions in losses in DeFi — understanding smart contract audits, protocol insurance (Nexus Mutual), and risk management is essential.

Bitcoin is digital gold — a fixed supply store of value. Ethereum is programmable money — a technology platform driving network effects. Many investors hold both for different portfolio roles and risk profiles.

Ethereum's fee burn mechanism destroys ETH with every transaction — during high network activity, more ETH is burned than created, making ETH potentially deflationary and supporting its store-of-value narrative.
