Is it illegal to copy a logo?

As a finance and cryptocurrency practitioner, I often encounter various brands and logos in my daily work. However, the question of whether it's illegal to copy a logo often comes to mind. So, here I pose the query: What is the legality of replicating or utilizing another entity's logo without proper permission? Do intellectual property laws apply to such an action, particularly in the realm of cryptocurrency and finance? And if so, what are the potential consequences for those who disregard these laws?
