Hi guys, can someone help me? Here's a background.

* Paper wallet generated from https://www.walletgenerator.net .
* Funds have been sent to this wallet over the past two years.
* 7 days ago, wallet was wiped out.
* Balance is now zero

Thinking back, I believe the mistake was made when generating the wallet. Instead of going offline, the wallet was generated while still connected to the Internet.

What are the chances of the BTC being recovered. I saw a company called hireahacker(.)com which appears to be genuine but in this type of marketplace how can you be sure? I would be very grateful for any opinions and more importantly whether there's any hope in recovering the stolen Bitcoins.

Thank you in advance.
