Of which part

If you'd like to see our growth, then feel free to come by our new offices Monday (should you be in South Florida--or anyone else).  You can even help us get these desks up the stairs because they don't fit in the elevator!

As far as people who have used our service so far, here is one post that comes to mind: http://www.everything-voluntary.com/2013/03/my-purchase-from-amazon-with-bitcoins.html  you can also find mention of us being used by others, in many places and languages(there are Japanese and Portuguese articles).

I understand your skepticism, and it is good to have it.  However the over $7,000 in purchases made through Bitspend by our customers since Monday, show that we are doing well enough a job of earning trust so far.  Now we will continue to do so going forward, and in the end be able to earn the trust and business of those, who like yourself, will wait for further validation of our business before using our service.  We accept that challenge!
