Why You Should Update

Etherscan is a de facto block explorer when it comes to Ethereum. Users visit their service to check if their transactions were mined, contracts deployed, and to find information about tokens that they buy, sell and use.

When you update information of your token, users can find your official website, email, blog, forums, social profiles, whitepaper, etc. Users love different channels of communication, so having many channels can be helpful for your project and token.
