Cryptocurrencies like Bitcoin exist entirely as digital data—ones and zeros exchanged between computers via the internet. Unlike traditional currencies backed by central authorities, cryptocurrencies rely on decentralized, tamper-proof software called blockchain to regulate transactions.
Understanding Cryptocurrencies
What Is Blockchain?
Blockchain is a distributed ledger technology that records cryptocurrency transactions across a network of volunteers' computers. Key features:
- Decentralized verification: Miners (volunteers) validate transactions using powerful computing hardware.
- Transparency: Every transaction is publicly recorded in "blocks" linked chronologically.
- Security: Cryptographic math prevents counterfeiting or fraud.
Major institutions like Goldman Sachs and Square are adopting blockchain for its efficiency in secure, peer-to-peer transactions.
Risks vs. Rewards
- Volatility: Bitcoin’s value has swung from $1 (2011) to $9,000 (peaks). Daily fluctuations can exceed thousands of dollars.
- No safety net: Unlike stocks or banks, cryptocurrencies lack regulatory safeguards. As one investor noted, "Buying $1 of every cryptocurrency might leave you with worthless assets."
- Long-term potential: Despite risks, early adopters like Brett Gibson (who bought Bitcoin at $20) have seen significant returns by holding through market cycles.
