Significant Bug!:


A code audit was just conducted on Ether.Camp’s HackerGold Smart Contracts – see EtherCamp’s Hacker Gold (HKG) public code audit.

There have been some complaints about the USD 50 million (4,000,000 ETH) cap, and investors basically get voting rights to the Hacker Gold competition, and the ethers raised go towards building the Hacker Gold virtual accelerator platform, not the startups competing on this platform:

Update Oct 20 2016 And two potential judges have declined:

To purchase Hacker Gold tokens, just send ethers to the contract address 0xb582baaf5e749d6aa98a22355a9d08b4c4d013c8, with a gas value of 100,000. The method () payable calls the method createHKG(...) that will generate the tokens for your sending address. Do it at your own risk – send a small amount first to confirm that it works as you expect. The HKG tokens are ERC: Token standard #20 compliant.
