It's a very good question! We think it can be answered by looking closely at the trading service we aim to provide. TradeConnect will facilitate trade between users, and the trustless blockchain system provides the structure to achieve this. Of course many exchanges exist that are positioned as authorities over their clients, at TradeConnect we are using the public ethereum blockchain to bring the benefits of transparency, immutability and security to our exchange.
To gain the benefits of the blockchain the most effective model is to use a bespoke token for a project to power smart contracts on th ethereum network, and that's why TCO is an essential feature of the platform.
Does this answer your question?
Goid answer, and a good question. Questions like that need to be asked to remind us why we are here in the first place.
