Spot trading basics

Spot trading is buying or selling the actual asset for immediate delivery — you own what you buy. It's the simplest trade: you go long (buy hoping price rises) or, with borrowing, short (betting on a fall). Most beginners should master spot before touching leverage.

💡 A spot trade

You buy 0.1 BTC at $60,000, spending $6,000. You now own 0.1 BTC. If BTC hits $66,000, your position is worth $6,600 — a $600 gain. You can hold it in your own wallet. No liquidation, no interest — just ownership.

Wallet types

Hot wallets (apps, browser) are connected to the internet — convenient but exposed. Cold wallets (hardware, paper) are offline — secure but less convenient. Custodial wallets (on exchanges) are managed by others. The right mix depends on amount and frequency of use.

Key management is the whole game

Every story of lost crypto is a key-management failure. The discipline: one offline copy of your seed, never digital, never shared, protected from fire and theft. A $10 hardware wallet protecting $100,000 is the best insurance in the market.

💡 The $1M lesson

People have lost fortunes to a single screenshot or a phishing site that asked for a seed phrase. No legitimate service ever asks for your seed. Internalize this: the moment someone asks for your seed phrase, it's a scam — full stop.

Position sizing from day one

Even in spot, decide the size before you click. A common beginner error is going all-in on one asset. Position sizing (how much per trade, how much per asset) is a skill you'll formalize later — but the habit starts now.

❓ Quick check

In spot trading you:

A) Borrow to trade
B) Buy and own the actual asset
C) Only short
D) Trade futures

Key takeaways

  • Spot = buy and own the asset; master it before leverage
  • Hot = convenience, cold = security; match wallet to amount
  • Never share your seed phrase — key management is everything
