Pros:
Tachain stands out from its competitors because of its large and comprehensive applications on the advertisement, transport and entertainment industry at the SAME TIME. Its blockchain-based nature guarantees transparency (of operation) and privacy (of users). This is often what is lacking in the advertisement and transport industry where user data are sold to make profits. Tachain, by contrast, enables users to EARN without compromising their privacy.
It is reliable to me because its first application is out, indicating that they are dedicated to making Tachain a better token. Moreover, it has passed the ICO KYC Report. That means some of its team members have already had their identity checked, raising the team's credibility.
Cons:
Although the Whitepaper looks good, it could be more detailed.
More team members might be needed to develop Tachain in the future to cope with the demand.
