Seems a little sketch, I would just be careful. If you're looking for a chance to get free BTC I know HBUS (hbus.com) is offering prizes if you're one of the thousands to register with them. I would check it out on their website and it's more safe.
im not looking to get free bitcoins but dude i wouldn't mind if they're giving me away 1btc so im just making sure if it's legit or not
