How to Buy and Trade Cryptocurrency
Method 1: Spot Trading (Most Common)
Process:

Common Cryptocurrency Mistakes
Mistake 1: FOMO (Fear of Missing Out)
Problem: Buying after massive price increase
Solution: Wait for pullback, DCA instead, stick to plan
Mistake 2: Not Securing Assets
Problem: Leaving large amounts on exchanges (risk of hack)
Solution: Use hardware wallet for holdings, only keep trading amount on exchange

Common Scams:
- Fake giveaways ("Send 1 BTC, get 2 back!")
- Pump and dump groups
- Ponzi schemes promising guaranteed returns
- Fake exchanges/wallets
- Phishing emails
Protection: If it sounds too good to be true, it is. Never send crypto to "verify" account or get bonuses.
Mistake 4: Trading Shitcoins
Problem: Gambling on unknown, low-cap tokens
Solution: Stick to top 50 coins by market cap until experienced
Mistake 5: Not Understanding Taxes
Reality: Crypto is taxable in most countries
