Ziftrcoin vs. Zrcoin

So I asked a question earlier but I didn't get any comments or responses so I check a few more exchanges and found out that another cryptocurrency is now using the abbreviation ZRC. ZRC use to be the letters for Ziftrcoin. We all know if hasn't done anything in a couple of years now but I've still been watching it because I mined about 25,000 Ziftrcoins a while ago. Since Zrcoin now has the letters ZRC I guess my 25,000 Ziftrcoins are worthless. I know there were some other people on a couple of blogs wondering the same thing. Hopefully this will help some others. Here is proof that someone is getting the two mixed up.
