What will be the change in exhange rates in btc approximately after august , when"the butterfly labs" deliver their products fully ? Because when we order them now the lab says that they can deliver the products approximately in last weeks of july or in the beginning in august...
Because on their FAQ they say :
We plan on shipping the ASIC versions of our products by the end of April. We have orders that date back to June of 2012. Those are the orders that will be delivered first. Orders placed now will not ship until the month of July.We cannot disclose the number of orders we currently have. Shipping of new units is still anticipated to begin by the end of April, 2013. We are unable to predict accurate wait times until shipping begins.
We currently do not have the ability to easily disclose the number of orders we currently have. Shipping of new units is expected to begin soon. It is unknown at this time when we will complete the shipping of our pre-orders. Even though we should start shipping soon, orders placed now will be shipped at a later time. Our orders date back to June, 2012. All of those orders and those placed since then will be shipped before new orders.
And they add their 1/3 shipping plan : Because of the potential for massive disruption that our ASIC units may cause to the mining ecosystem, we are instituting a 1/3 shipping method for our first shipment of products to individuals. So that no single person or handful of people are able to gain a material advantage over any other, we will ship all our available units at the same time to as many customers as we can. This means we will likely delay shipping on our first units until we have accumulated enough stock to satisfy a significant portion of our initial orders. This ensures that as many people as possible who are early adopters are equally and fairly treated when receiving our product. To that end we will be shipping our first orders as such: 1/3 of each product line (Jalapeno, Single SC and Minirig SC) will be shipping to new orders, 1/3 to upgrade orders and the final 1/3 will be shipped to a random selection of orders from the first two categories (both upgrade and new customers) received in the first month of orders (From 23 June 2012 to 22 July 2012).

Any foresight about future changings in value in the exchange rates after august , with the new quality butterfly products on the bitcoin market, knowing that the bitcoin ecosystem is very unreliable....
