I'm not sure the full extent of this yet but one thing this does effect is if you had that coin on the bottom ticker bar it will not show a value anymore.
Yikes! That's not cool.. totally unintended consequence..
My suggestion would to be re-add the coin under a slightly different tag and re-add it to the bottom :/
Yes, but remember the price only updates when you update the stats so it's almost pointless to have an added coin which doesn't update on your ticker...
