Colossus coin & the old Coinedup Exchange

Boy am I glad that I did'nt check any alt-currency related news for the past 2+ years now Huh

Please correct me if I am wrong, but basically my 1,100,000+ coins purchased 2+ years ago are worthless because I missed the deadline for the exchange to the new version of colossus coin?

That would just be my luck, sitting at current market value that is a $11,000+ kick in the nuts...

I was recently cleaning out an old laptop and found a text document that I saved where I bought around 10 or so random alt-currencies. The amounts I have and the date I purchased them, etc.

Either way I don't think it matters because the exchange I was holding them all at, coinedup.com - appears to be belly up. Does anyone know any info on them or? I pretty much assume any exchange that disappears takes all the coins with them, and you are just SOL, right? Last news i see from them is from 2013-2014 and apparently everything was converted into bitcoin but I have no way of contacting now. I found a userame on reddit and some obscure info on the net about companies he started in the past.

Thanks for your help guys. I forgot my login to original account, but over the years this forum has been a huge asset to me through my crypto journey!!
