Just curious, since dent is an erc-20 token how does Ethereum make money from any transactions that occur? Can someone shed any light on this?
Ethereum doesn't make money out of it, its just the platform used by this DENT token. ETHER however is the currency that is used as gas when sending DENT tokens just as ERC tokens were sent. ERC tokens spends gas when sending transactions which cost ether token.
Having DENT exchange itself will make this project more powerful in their own platform. I guess dent will also be a utility token in that case.
