How to find GST cost?

Could you please explain, in simple terms, how one might go about determining the Goods and Services Tax (GST) cost associated with a cryptocurrency transaction? Are there any specific tools or methods that are commonly used to calculate this, or is it a more manual process? Additionally, are there any factors that might affect the GST cost, such as the type of cryptocurrency being traded or the country in which the transaction takes place? I'm particularly interested in learning how to accurately account for GST when dealing with cryptocurrency, as it's an area that can be quite complex and confusing for many individuals.
