What SCP is free?

Could you please clarify what you mean by "SCP"? If you're referring to a specific service, platform, or cryptocurrency related to the finance and cryptocurrency industry, it's important to note that most services, especially those involving security, custody, and trading of digital assets, come with some form of cost associated with them. However, if you're looking for free resources or services related to cryptocurrency and finance, there are certainly some options available. For example, many cryptocurrency exchanges offer free basic trading services, and there are numerous open-source projects and communities that provide free educational resources and tools for learning about blockchain technology, cryptocurrency, and finance. If you're interested in learning more about these types of free resources, I would recommend exploring the official websites of popular cryptocurrency exchanges, joining relevant online forums and communities, and searching for open-source projects and educational platforms that cater to your interests. Keep in mind that while some services may be free, you should always carefully evaluate their security and reliability before entrusting them with your funds or personal information.
