The DGT is a native currency to the DGB. In particular the design explicitly used the DGT for transaction execution similar in concept to Ethereum GAS. All mining rewards are in DGT. As the objective of being a global reserve currency, it is intended to be used to price assets on the DGB for exchange of value (e.g. purchase and sale of assets). Using a “zero inflation” economic model, the DGT is further expected to accrue in value compared to other reserve currencies over time (e.g. the $USD and EUR).
