How to get GT protocol?

Could you please elaborate on the steps involved in acquiring the GT protocol? Is it available for purchase on cryptocurrency exchanges, or is there a specific process one needs to follow? Are there any prerequisites or eligibility criteria that must be met in order to obtain the GT protocol? Additionally, are there any associated costs or fees that come with acquiring the protocol? I'm particularly interested in understanding the accessibility and feasibility of obtaining the GT protocol for those new to the cryptocurrency space.
