Crypto & Web3
A structured, investor-focused learning track to understand blockchain assets, build a resilient crypto portfolio, and explore DeFi, NFTs, and more.
Crypto & Web3 is a new financial and digital ownership layer enabled by blockchain networks. It includes assets such as Bitcoin and altcoins, decentralized financial services (DeFi), tokenized communities and digital collectibles (NFTs), and the infrastructure that secures networks (including mining). This category is designed to take you from foundational understanding to practical decision-making—how the technology works, how to allocate responsibly, how to evaluate opportunities, and how to protect capital in a high-volatility environment.
• Beginners who want a clear, reliable entry point into crypto without speculation-driven noise
• Investors who want frameworks for allocation, portfolio construction, and risk controls
• Learners who want to understand DeFi, NFTs, and mining as investable sub-sectors—not trends
Who this is for?
• Technical literacy (blockchain, wallets, tokens, smart contracts) to assess projects independently
• Portfolio structure and allocation logic aligned with your risk tolerance and time horizon
• Practical models for weighing potential return against operational and market risk
What you will gain!
DeFi Mastery — Be Your Own Bank

Crypto Portfolio Builder — Altcoins, Wallets and Strategy
Build a portfolio process you can actually follow: allocation logic, position sizing, rebalancing discipline, custody choices (self-custody vs. intermediaries), and how to evaluate altcoins without emotion or hype-driven decision-making.

• Assess projects and narratives with a structured checklist (use case, token design, adoption signals, liquidity, risk)
• Separate credible return drivers from marketing claims and noise
4) Navigate DeFi with risk-first thinking
• Understand yields, collateralization, liquidations, and core protocol mechanics
• Evaluate smart contract, liquidity, and counterparty risks—and apply practical controls
5) Approach NFTs and mining as investable sub-sectors
• Analyze NFT opportunities using valuation logic, liquidity awareness, and cycle context
• Estimate mining economics using cost drivers and profitability assumptions
