@mikey: Have you staked all the time? I started a year ago and with some help the wallet still works.
About the Team requirement: This shall be lifted in the foreseeable future.
About payment: I can confirm that I managed to pay for something real by:” I changed GRC to BTC at the http://www.poloniex.com exchange then I forwarded it to my http://www.xapo.com account and paid with the recently acquired Debit card from http://www.xapo.com. I do not know and I do not want to know, how much I lost in all the fees on all these steps, but it works.”
I figured out, that I might fill my tank of my car once in a month (at the value of USD 0.04/1.0 GRC), and still save some coins for the next spike of its value – but do not get too enthusiastic, it does not pay the electric bill nor pay back the computer components. But as I am “boincing” since 2004, this does not really matter to me.
