How much GST do I pay?

Good day, I'm curious about the specifics of GST payments when it comes to cryptocurrency transactions. Could you please elaborate on how much GST one typically pays on such transactions? Are there any specific rules or regulations that govern the taxation of cryptocurrency in this regard? Additionally, are there any exemptions or deductions that can be applied to reduce the GST burden? I'm eager to understand the financial implications of engaging in cryptocurrency transactions and how they differ from traditional financial transactions. Thank you for your assistance.
