If you sign up for Coinbase and deposit or trade $100 dollars they will send you an additional $10 dollars worth of Bitcoin. That is a instant 10% return on your deposit of $100 dollars! Keep in mind Bitcoin has gone up by thousands in the last year. The only way to get your FREE $10 dollars is via this link:

If you sign up without a referral link you WILL NOT get $10 dollars in free Bitcoins. This is not a scam! Coinbase will give me a referral rewards for your sign up and you will also get one too. Don't make the mistake I did and sign up without a referral and lose out on a 10% instant return on investment.
