I have been farming when afk, for a little while now. Obtained about 4btc, and thinking the service from
http://www.spendbitcoins.com/ will be a great way to use these bitcoins.
However, I am unsure what I desire to purchase as of yet. Along with the btc price variance, I am wondering.. Can I use their referral to buy a giftcard and pay for it with their giftcard? So I can 'Cash out' so to speak?
