This point has been made before, but if Avalon is not trying to get people to send them money, there is not a real good reason to expend a lot of effort on proving that they actually have something.
Under the hypothesis that they have gear and a pretty anticipated production rate going forward, a good psychological strategy would actually be to let doubt and accusations build to a crescendo, then just go ahead and make their early deliveries without a lot of fan-fair. The effect that would have would be to quash a lot of future doubt in whatever projects are to come.
I, of course, have no idea if Avalon is legit, total scam, or something in between. I hope they are legit because I am starting to feel that it might make sense to get into mining (although not particularly for an immediate profit) and the basic design these guys elude to is compelling to me.
I do wish Avalon were more forthcoming with information, and that they are not counts as a negative to me, but as I mentioned it could be the case that there is not a compelling business case to be. And they are likely fairly busy. If they do not take the time to work on transparency at some point I can be pretty confident that they'll not count me as a customer.
Customers that request a refund at this stage should not be surprised to discover the queue of willing customers desperate to pre-order devices as they become available.
This project has a good track record of not taking pre-orders for a future batch.
I recall Tom from bASIC also did not want to take orders on the 2nd batch, however people insisted that he continue taking pre-orders.
That should help put into perspective what bASIC's initial batch would cost to complete.
In retrospect the steps taken by this project team have worked in keeping them focused on the task at hand.
Short of any unforeseen events that may delay the project. The Avalon project and its team, have to contend with similar pitfalls that have delayed other ASIC projects.
Attempting to anticipate all possible outcomes is a waste of effort with such projects.
Hindsight is 20/20.
Keep up the good work.
