Thank you for the kind words, I'm always happy to see old members visit us again. I've never thought Cold Hacks will stay active for so long, especially when you consider it's based around a just single game but here it is

People often say that 13 is an unlucky number but this surely isn't true at Cold Hacks because we have just turned 13 and once again it's time to celebrate :) If you aren't our member, now it's the best time to join.

but I'm thinking of buying cold to relive the old days and have some fun. what I'm wondering is—can I run the cheat on virtualbox? would that cause any issues?

Yes, it would. It's strictly forbidden by our rules. Also anti-cheat of the game (both XignCode and EAC) detects virtual machines.

Generally system expects EXACT amount, so that's how you should pay. Use personal wallet instead of sending from exchange directly.

No and I strongly discourage playing on such private servers.

Of course, we wouldn't sell it otherwise.

This has been repeated in several other topics but I will state it once more. Payment process is automated if you send exact amount we expect within session time limit ( 20 minutes ). I know you have already contacted me via PM but for anyone reading this I will also say that in case of any payment ...

For payment issues send txid via PM.

I can see everything went fine. Confirmations happen in around 10 minutes after getting your first confirmation on the blockchain.
