The source

The information here was based on Where To Coin email notifications (pictured below). However, none of the coins have been announced by Bithumb, and have not been verified elsewhere.

It looks like the Where To Coin notifications are incorrect, and that the coins listed on this page are not currently coming to Bithumb.

This may or may not be construed as a reminder that fake news is rampant, and to always get your information from multiple sources.
