Alright, here's a little tutorial on how to do a QR code giveaway:

1. Head on over to https://www.bitaddress.org
2. Generate a new bitcoin address. (move your cursor around until it hits 100%)
3. Send the amount of bitcoin you want to give away to the QR code on the left ("share").
4. Post the QR code on the right ("secret") on Instagram or wherever you want to do the give away. You should be able to right click on the QR code and save the image.

Note: Never use bitaddress.org for creating addresses that will store large amounts of bitcoin... if you use this website, you will be trusting that they don't store the private key and take the bitcoins for themselves.

Thank you very much for the help. I have got one final question. If i were the reciever. Where would i need to use the private key in order to transfer the amount into my blockchain.info wallet.

Scanning a private key and transferring all of the bitcoins from the private key to a personal address is called "sweeping". It's kind of like redeeming a gift card online.
Most wallets have a feature like this.

Manually with Blockchain.info mobile app:
1. Open menu
2. Tap "addresses"
3. Tap the three dot menu in top right
4. "Import Address"
5. Scan QR code of private key
6. Create a transaction sending all of the bitcoins from the private key into your personal wallet. (Other people will be trying to do the same thing! You've gotta be faster than everyone else)
7. Archive/delete the private key that had the giveaway funds. You don't want to accidentally receive bitcoins there!

In Electrum:
1. Click "wallet" in the top menu
2. Click "private keys"
3. Click "sweep"
4. Scan QR

In anything else:
Look for anything that says something like "import private key", "sweep key", "redeem private key", "import paper wallet", etc.

Thank you very much mate. Now, I understand how it works.
