Cryptocurrency Explained: How It Works, Key Types, Benefits & Real-World Risks

Quick comparison:

What Can You Use Cryptocurrency For?

1. Making Payments

Thousands of online businesses now support payments via Bitcoin and other cryptocurrencies. From apps to airline tickets, crypto is emerging as a legitimate alternative to credit cards and cash.

Example: Apple now offers payment in 10+ cryptocurrencies on the App Store.

2. Investing

Most people think of crypto and think of general huge returns, but large price swings are also associated with crypto. It is fast becoming number one explored by investors expanding their diversification using something beyond gold and stocks

Note: I remember in late 2017 that Bitcoin fell from about $19,000 to about $7,000 — so be careful.

3. Global Transfers

Using a typical bank is expensive and slow when you are sending money internationally. With crypto, you can cut expenses and timing.

Example: Where a bank transaction can take about 3–5 days for cross-border transfer, with crypto, it can take 10 minutes and less than $1.

4. DeFi (Decentralized Finance)

Cryptos power an entirely new financial world where you can lend, borrow, or earn interest—without banks.

Pros and Cons of Cryptocurrency

Understanding both sides is key before getting started.

Benefits

• Inflation resistance: Fixed supply (like Bitcoin’s 21 million cap) protects value.
  
  

• Security & privacy: Transactions are pseudonymous and recorded on the blockchain.
  
  

• Lower fees: Especially for international payments or peer-to-peer transfers.
  
  

• No middlemen: You control your money directly.
  
  

Risks

• Volatility: Price swings of 10–30% in a day aren’t uncommon.
  
  

• Hacks: Exchanges can be vulnerable (e.g., Mt. Gox, Bitfinex breaches).
  
  

• Lost access = lost funds: Forget your wallet’s private key, and your crypto is gone.
  
  

• No refunds: Sent to the wrong address? You can’t reverse it.
