I don't know if anyone has tried but seems more than impossible to recover your coins from an extinct exchange such as Crypsy or Swisscex -just mentioning-. It is not -probably- like recover videos from past YouTube or Dailymotion accounts but curiosity is on the air.
There is no chance to access to an account from a dismantled exchange archived on the Wayback Machine. However, i have readed that there is many ways to recover a website from Archive.org and get access to an specific account and see what did you have then. The question lays on a possibility to recover a wallet cryptocurrency and withdraw your coins from an extinct exchange to your own wallet. Which could be more that not possible because it depends on the server.
The reason about i'm asking that is because i had some doges on Swisscex and i want to recover it from archive.org. But seems like it's huge late for do so and impossible to make that acrobatics. If someone knows how, please reply this thread...
