Why are you showing data that comes from the Yobit site that has the ION wallet under maintenance for over 2 weeks now??
Coinmarketcap is a reliable website for showing a cryptocoin's value and trading volume.
Your "internal" Ionomy exchange is irrelevant.
Did you just admit that ION still doesn't have a working wallet?
I just admitted that you are using two week old data from a source that has the ION wallet under maintenance for reason determined by Yobits... I believe that are trying to reconcile the old trades before starting new trades...
You should try the Ionomy Exchange were all the trading is currently happening... Soon other exchanges will be listing ION...
