The first step in buying cryptocurrency is to decide which coin you want to purchase. After researching the various digital coins available, research exchanges that allow you to buy and sell the particular digital coins you want to purchase. These exchanges will generally require you to create an account and provide personal information. You can then fund your account with fiat currency or other cryptocurrencies to begin trading the coins you selected. It is important to store the coins you purchase in a safe wallet, rather than leaving them on the exchange.
