This repository is a public beginner-friendly investment guide for readers who want to understand U.S. stocks, options, and crypto assets from the ground up.

The goal is not to tell readers what to buy. The goal is to help them understand what they are buying, where the risk comes from, how losses can happen, and what should be checked before putting real money at risk.

## What this guide covers

- U.S. stock basics: trading hours, order types, ETFs, financial statements, valuation, and market structure.
- Practical trading checks: bid/ask spread, liquidity, slippage, position sizing, and exit rules.
- Options basics and risk: calls, puts, Greeks, implied volatility, assignment, expiration, and defined-risk spreads.
- Crypto basics: wallets, private keys, stablecoins, perpetual futures, smart contracts, DeFi, and on-chain risk.
- Risk awareness: leverage, liquidation, phishing, approval risk, token unlocks, bridge risk, and market cycles.

## Why U.S. stocks and crypto?

U.S. markets remain among the deepest and most liquid capital markets in the world. They also provide abundant public disclosure, making them useful for learning how companies raise capital, generate cash flow, and get valued by the market.

Crypto extends dollar-denominated value and financial primitives onto public networks. Stablecoins such as USDT and USDC make it possible to move dollar-linked value across exchanges, wallets, and blockchains, but they also introduce issuer, reserve, redemption, blacklist, smart-contract, and depeg risks.

Studying both markets gives beginners a broader map: one side is company ownership, cash flow, and securities markets; the other is digital assets, stablecoins, smart contracts, and open settlement networks.
