What was once a nascent idea considered a unique but useless hobby has gradually transformed the global financial system. In the Bitcoin network, miners receive Bitcoin (BTC) rewards for validating transactions, and individuals can acquire Bitcoins through various exchange platforms.

Data linked—or chained—between blocks is what led to the ledger being called a blockchain. Sometimes, schemes like One Coin have claimed to be cryptocurrencies, but have then turned out to be nothing more than well-organised pyramid frauds backed by a centralised database. The BBC carried out an investigation into this recently in their ‘The Missing Cryptoqueen’ podcast series. Keep in mind that Bitcoin itself is a speculative asset with no intrinsic value, which means it won’t produce anything for its owner and isn’t pegged to something like gold. Your return is based on selling it to someone else for a higher price, and that price may not be high enough for you to turn a profit.
