How do I send cryptocurrencies from my wallet to another wallet?

As a cryptocurrency investor, I'm curious about the process of transferring digital currencies from one wallet to another. Could you please elaborate on the steps involved in this transaction? I'm particularly interested in understanding the security measures that should be taken to ensure a smooth and secure transfer. Additionally, I'd like to know if there are any specific fees or limitations associated with sending cryptocurrencies, and if there are any recommended practices to avoid any potential issues or delays. Clarifying these details would greatly assist me in successfully transferring my digital assets to another wallet.
