Investing & Retirement
Compounding, retirement accounts, withdrawal strategy, annuities, and crypto treated as an asset class.
Money that is meant to grow. Compound interest and contribution schedules, 401(k) and IRA projections with employer match, Roth versus traditional comparisons, FIRE numbers and coast-FIRE dates, safe withdrawal rates and sequence-of-returns stress tests, and annuity income.
Investment literacy tools cover expense ratios and fee drag, dollar-cost averaging versus lump sum, rebalancing bands, and risk-adjusted return measures.
Crypto appears here as an asset class — staking and DeFi yield, impermanent loss, portfolio weighting and tax lots — while mining and blockchain infrastructure sit in Technology.
