⚡ 60‑second snapshot

  • What it is: Digital cash secured by math, run by a network—not a company or bank. The breakthrough is solving “double spend” with proof‑of‑work and a public ledger (the blockchain).  
  • Core rules: Supply is capped at 21,000,000 BTC and new coins are issued on a predictable schedule that halves roughly every four years.  
  • Finality: Transactions can’t be reversed; only the recipient can refund. Double‑check before you send.  
  • Everyday payments: For quick, tiny‑fee payments, many wallets use Lightning, a layer‑2 network of payment channels.  
  • Simple exposure: In the U.S., you can also buy spot Bitcoin ETFs in a regular brokerage account.  
  • Taxes: In many places (e.g., the U.S.) Bitcoin is treated as property; selling or spending can be taxable. Keep records.  

1) How Bitcoin works (no jargon)

  • Think of a global spreadsheet anyone can verify. New pages (“blocks”) are added about every 10 minutes by miners solving cryptographic puzzles; the rules target ~6 blocks/hour and adjust automatically.  
  • Your wallet holds keys (not coins). A private key/seed phrase controls your funds; anyone with it can spend them. Guard it like treasure.  
  • The protocol’s monetary policy is fixed: at most 21M BTC, divisible to 0.00000001 BTC (a satoshi). Issuance halves on a set schedule (the “halving”).  
  • Irreversible by design: once confirmed, a payment can’t be undone—only refunded.  

2) How to 

buy

 (pick your path)

A. Spot Bitcoin ETF (hands‑off, no wallet needed)

Buy like any stock in your brokerage account; it tracks spot BTC. You won’t self‑custody the coins, but it’s simple for retirement accounts. (Approved in the U.S. Jan 10, 2024.) 

B. Crypto exchange (to self‑custody later)

  1. Create an account and verify identity.
  2. Deposit fiat and buy BTC (watch fees).
  3. Withdraw to your own wallet once you’re comfortable (see below).
    (Tip: start with a small test send.)

C. Peer‑to‑peer

Buy from individuals/OTC desks. Use escrow and meet in safe, public places. Only for confident users.

3) How to 

use

 Bitcoin (send, receive, spend)

  1. Choose a wallet (mobile, desktop, or hardware). A helpful, neutral directory: bitcoin.org’s wallet chooser.  
  2. Back up your seed phrase on paper/metal, offline. Never type it into a website or share it with anyone—ever.  
  3. Receive: Share your wallet’s address or let someone scan your QR code.
  4. Send: Paste/scan the recipient’s Bitcoin address → pick a network fee → send. Remember: no chargebacks.  
  5. Everyday payments: Use a Lightning‑enabled wallet for near‑instant, low‑fee payments via invoices/QR codes.  

4) How to 

invest

 smart (keep it chill & cheerful)

  • Decide your why: savings tech, censorship resistance, or macro hedge.
  • Position sizing: Only what you can ride through big swings.
  • DCA beats FOMO: Small, regular buys reduce stress.
  • Custody choice:
    • ETF/custodial = convenience, familiar accounts.  
    • Self‑custody = full control/responsibility (you hold the keys). Use quality wallets and backups.  
  • Taxes: Track cost basis. In the U.S., selling/spending is a taxable event; mining and income paid in BTC are taxable too. Consult local rules/pros.  

5) Safety first (non‑negotiables)

  • Seed phrase offline, duplicated, and stored securely. Test you can recover from backup.  
  • Withdraw from exchanges to your own wallet if you want self‑custody.
  • Double‑check addresses (beware “address‑poisoning” look‑alikes).
  • 2FA on accounts, avoid SMS if possible; beware SIM‑swap scams.
  • Do test sends before moving large amounts.
  • Only download wallets from official sources; keep devices updated.

6) Common gotchas (skip the stress)

  • Sending BTC to the wrong network/coin (e.g., BCH or a random “BTC” token) → funds likely lost.
  • Fee confusion: High on‑chain demand = higher fees; Lightning helps for small payments.  
  • Losing your seed phrase = losing access. Back it up before you fund the wallet.  

Your happy‑path 

10‑minute plan

  1. Use the wallet chooser to pick a beginner‑friendly, non‑custodial wallet.  
  2. Write down your seed phrase (offline).  
  3. Buy a small amount of BTC (exchange or ETF; ETF is exposure only, no self‑custody).  
  4. If you bought on an exchange, withdraw a test amount to your wallet.
  5. Try a tiny Lightning payment to experience instant settlement.
