Currently Coinstash has a promotion, offering new users who sign up with a referral link free $10 in Bitcoin
Upon signing up with the referral link the $10 of bitcoin will be added to your CoinStash account. However unfortunately the minimum trade size with Coinstash is $20 AUD, so you will need to deposit more than $20 AUD, buy Bitcoin and then sell it to cash in the referral bonus
While this isn't exactly 'free money' like many other promotions on this site, it is a great offer for users thinking of using Coinstash
Here is how it all works
Sign up to CoinStash with the referral link. Make sure to use a web broswser
Now that you have been credited with $10 in your account the next step is claiming it
You will need to depoit more than $20 into your account
From this you will need to buy Bitcoin
Now you can sell your entire Bitcoin balance, claiming the referral bonus
