What is the cheapest method for transferring funds from Coinbase to Kraken?

The cheapest method to transfer funds from Coinbase to Kraken generally involves withdrawing the funds in a cryptocurrency that has low transaction fees and then depositing those into Kraken. One would typically use a cryptocurrency like Litecoin (LTC), Ripple (XRP), or Stellar Lumens (XLM), as they usually have lower withdrawal fees on Coinbase and also lower deposit fees on most exchanges, including Kraken. However, users must first ensure that both exchanges support the chosen cryptocurrency. After converting the funds to the preferred low-fee cryptocurrency, they can withdraw it to their personal wallet or directly to their Kraken deposit address. It's important to double-check addresses and transaction details, as mistakes can result in a permanent loss of funds. Once the transfer is confirmed, the funds can be traded on Kraken for other cryptocurrencies or fiat currency as needed.
