VeChain Thor Token by fact is the branch token of the VeChainThor ecosystem. It primarily functions as the gas for transactions. This token often represents the hidden charges of using the VeChainThor blockchain. The charges are usually used up after some specific blockchain operations are done. The size of data that is sent through the VeChainThor blockchain is what determines its transactions and the amount of VTHO needed. Something to note down is you should not confuse between the transaction cost and VTHO is price. These two are quite different from each other.
The transaction cost of the VeChainThor network is calculated by multiplying the amount of VTHO needed to the current price of VTHO. Take a look at this: if you increase the generation of VTHO the transaction rates will be lowered whereas the vice versa will increase the transaction cost. Also, if you increase or decrease the amount of VTHO the transaction price will be influenced by this action either way.
