Coinbase Referral: https://www.coinbase.com/join/59ce6c6b48662a02fd000e46
Sign up and get an extra $10 worth of Bitcoin once you spend $100 or more. Quickest way to buy Bitcoin. You can use your credit card on this site and have it instantly rather than waiting for a wire transfer.
Bitconnect Referral: https://bitconnect.co/?ref=mfouz32
On this site you use your Bitcoin to buy Bitconnect coins. You then lend out those coins and earn interest on them which usually amounts to 1% per day. So if you loan out $100 that's $1 per day. You can also easily reinvest your interest earnings so the amount you are earning daily can increase fairly quickly. This referral will give you a bit of help once you make your first loan.
Free Bitcoin Referral: https://freebitco.in/?r=9281552
This will only get you small amounts of Bitcoin at a time but it's absolutely free. Every hour you can click the "roll" button and you win varying amounts of Bitcoin. Once your balance builds up enough you can earn interest on it too and there is also a lottery that they run with the top prize being actually quite substantial. This referral code will allow me to share some of my balance with you based off of how much you use the site.
Any questions feel free to ask. Hope this has been helpful.
