To use Apple Pay to purchase Ethereum, you must first have your Apple wallet loaded with your credit or debit card. This option is ideal for anyone who is hesitant to expose their credit card information on a cryptocurrency exchange. The next step is to use the Apple wallet on a cryptocurrency exchange that supports it, such as Coinbase. After logging in, choose ether as your purchasing cryptocurrency and apple pay/wallet as your payment method. The last step is to confirm your order and save your purchased Ethereum to your ether wallet.
