From my understanding, you have to go to their website to request an invite, and I made such an invitation request about a week ago.
However, I have received No invite from them, so far.
I would also be curious whether anyone has used their service(s) to purchase and/or sell bitcoin, yet.
I requested and no invite. Several days ago there was a blog post on their site answering questions and it seems the #1 question was, where is my invite? The following is part of their answer.
We are not in general release whatsoever.
Making this worse from a Bitcoin pro’s perspective: The product is designed for casual consumers, so the initial invites have gone to those sorts of profiles rather than those who already breathe ECDSA crypto and the like. We’ll certainly expand, as we need the harsh feedback of the pro Bitcoiners just as well, but we will not expand quickly enough to please everyone.
Profiles? My "profile" consisted of my name and email address. The answer seems to be that we are still in the hype phase and that their answer is bullshit.
Thanks. Their answer seems a bit strange to be attempting to expand into a certain kind of user based on their invitation request. Probably, they fear that people will over use their site if they expand very quickly at all - b/c zero fees will create a trading incentive (like what goes on in china). Zero fees seems to good to be true.
I agree that zero fees seems too good to be true. One thing I noticed in their demo youtube is that when making a deposit it lists both a circle fee and a bank fee, but they are both set to FREE. This might indicate that the coding to handle fees is already there, so they can easily add the fees in the future.
