From Bitcoin’s dizzying highs and lows—hovering around $62K in June 2026—to the complex terms like blockchains and ETFs that make your head spin, here's a handy guide. Bitcoin, once seen as Donald Trump's pet project, has its critics and enthusiasts who see it as a beacon of financial freedom.

Blockchain, the tech behind Bitcoin, is like a giant digital ledger where every crypto transaction is recorded. Miners validate transactions for rewards, but the system can be both lucrative and energy-intensive.

The term 'halving' refers to when miners earn half as many coins per transaction—this happened in April 2024. It's all about balancing supply and demand, but some may wonder if it's worth the energy cost.

Crypto exchanges are like online markets for trading cryptocurrencies, complete with fees. Crypto wallets come in two forms: hot (online) or cold (physical devices), each offering a different level of security.

Ethereum is another major player, and its blockchain supports non-fungible tokens (NFTs). In 2022, it switched to a more sustainable energy model. ETFs add an intriguing layer with portfolios that mimic the performance of various assets, including Bitcoin itself.
