OK, it seems that I made a mistake which is not cool about this stuff of swape...

Is that true that if I transfered my coins from Bittrex to my "old" wallet
there is nothing which can be done??

This is insane....

Now, other part of the question is what do we have to do with our current coins
in our desktop wallet AND in the exchange?

Sorry, I am really not techy, and just the name swap is making me swet.

Could I get some guidance ?

thanks in advance
