When adding cryptocurrency to your Coinbase account, it doesn’t directly link with your personal wallet; instead, your Empower account uses public data for a secure glimpse at prices of tokens across dozens of exchanges – helping over 3 million households track net worth, plan financial goals and manage cryptocurrency portfolios.

Coinbase’s fees are simple and clear: each transaction incurs a flat fee plus an average spread; these costs will be displayed on the order page before you complete your purchase or sale, along with how much USD must be sent for completion on the confirmation screen. ACH transfer transactions from banks or your Coinbase USD wallet do not incur fees at all!

Coinbase makes it possible to earn additional cryptocurrencies by staking, which involves pledged your coins to assist in processing transactions on the blockchain. Although the process is complex, the rewards are plentiful: newly minted crypto will be paid out as your payment and learning rewards may also be given in return.
