Cryptocurrency trading involves speculating on the future value of a given virtual currency or using it as an investment to make profits. Trades are typically made in pairs, where one currency is bought and sold in exchange for another. For example, a trader may sell Bitcoin for Ethereum or purchase Ripple with Litecoin. Traders can use technical analysis to make decisions about when to buy or sell by examining past market data, such as prices, volume, and candlestick charts, in order to predict price movement and make informed decisions about their trades. Traders should also pay attention to news related to cryptocurrency in order to assess the overall sentiment of the market.
