 TITLE: What Is Ethereum and How Does It Work? CONTENT: How to Buy Ether\n----------------\nAs the second-largest cryptocurrency by market cap (behind Bitcoin), Ether can be purchased on many major cryptocurrency exchanges. Popular options include Binance.us, Coinbase and Gemini.\nTo purchase and possess Ether, you'll first need to set up a digital wallet. The safest option is to use a \"cold\" wallet that isn't connected to the internet, such as a thumb drive with your Ethereum account information. Some exchanges offer wallets or can store your cryptocurrencies for you. This is a more convenient option, but it puts your cryptocurrencies at risk if the exchange gets hacked or goes under.\nGenerally, the cheapest way to buy cryptocurrencies on an exchange is to transfer funds from your bank account or use a debit card. Some exchanges accept credit cards, but you may have to pay additional fees to both your card issuer and the exchange. END
