<p>Let’s look at a national currency like the rupee. It can be deposited in your name at a bank, or privately stuffed into a mattress at home far away from anyone’s eyes.</p><p>Similarly, a cryptocurrency can be held on your behalf by a company, usually in your wallet at a crypto exchange online. You could also hold it in without being affiliated to anybody, in a private cryptocurrency wallet.</p>

<p>Some cryptocurrencies like Bitcoin and Ether are designed to have a limited supply. By comparison, real-world currencies like the US Dollar do not have a hard limit on supply. When demand increases, the value of a supply-limited item is expected to increase.</p><p>That difference in supply, a high demand for crypto and new ways to profit from rising crypto, have led to a self-perpetuating cycle that drives up the exchange value of major cryptocurrencies.</p>

<p>Fundamentally, a seller sells their currency to gain cash and a buyer buys expecting to hold the currency until its value increases in dollar/rupee terms.</p><p>In mid-August 2021, the total market value of all cryptocurrency exceeded $2 trillion, with Bitcoin alone making up 44% of that. As the graph above shows, a currency can start small and reach very high – but with a number of bumps along the way.</p><p>People with a lot of faith in the future of cryptocurrencies subscribe to a ‘HODL’ mindset, meaning ‘hold on for dear life’ to the roller-coaster they expect to ride. They buy and do not intend to sell anytime soon, even claiming that the value of one Bitcoin could rise from $50,000 today to $288,000 in a few years.</p><p>Others choose the day trading route – buy a currency, target a profit percentage as low as 2% and sell as soon as that target is reached – sometimes within hours.</p>

<p>For beginners in the crypto market, experts advise investing only as much money as you’re willing to lose. The reason is, crypto trading marries the ‘irrational exuberance potential’ of a conventional stock market to the regulatory uncertainty of crypto.</p><p>Also, hackers have shown that anything financially valuable on the internet is a juicy target. However, crypto exchanges that hold user wallets try to stay safe by employing armies of security experts and paying ‘bug bounties’ to external consultants who identify vulnerabilities.</p>
