 <h2 id="understanding-cryptocurrencies">Understanding Cryptocurrencies</h2>
 <p>Understanding cryptocurrencies involves grasping the core of blockchain technology, recognizing the different types of digital currencies, and comprehending the concept of decentralization. These elements are fundamental to navigating the world of crypto investments.</p>
 <h3 id="blockchain-fundamentals">Blockchain Fundamentals</h3>
 <p>Blockchain is a decentralized ledger technology. It records transactions across many computers. This setup ensures that the registered transactions cannot be changed retroactively. Each transaction added to a blockchain is called a &amp;quot;block.&amp;quot; These blocks form a &amp;quot;chain&amp;quot; as they link together in sequence.</p>
 <p>In a blockchain, each participant has access to the entire ledger. This transparency guarantees that the information is consistent and secure. The use of cryptography in blockchain ensures data integrity and security. Smart contracts are digital agreements that automatically execute when conditions are met, further enhancing functionality.</p>
 <h3 id="types-of-cryptocurrencies">Types of Cryptocurrencies</h3>
 <p>Cryptocurrencies include a wide range of digital coins, each serving different purposes. The most well-known is Bitcoin, often called &amp;quot;digital gold.&amp;quot; It is used primarily as a store of value. On the other hand, Ethereum supports smart contracts and decentralized applications (dApps).</p>
 <p>There are also <strong>altcoins</strong>, which are any cryptocurrencies other than Bitcoin. Examples are Litecoin, Ripple, and Cardano. Each has unique features like faster transaction times or different consensus mechanisms. <strong>Stablecoins </strong>are another category, typically pegged to a stable asset like the U.S. dollar to reduce volatility.</p>
 <h3 id="decentralisation-explained">Decentralisation Explained</h3>
 <p>Decentralization is the distribution of power and control from a central authority to many smaller entities.
