What is the total supply of NGL?

Could you please elaborate on the total supply of NGL? As a cryptocurrency enthusiast, I'm particularly interested in understanding the underlying economic principles and mechanisms that govern this digital asset. Specifically, what is the maximum number of NGL tokens that can ever be created? Does this supply remain fixed or is there a mechanism for adjustment over time? Additionally, is the supply distributed in a certain manner, such as through mining or staking rewards? Understanding these details would greatly aid my analysis of NGL's potential value and market position.
