Do you plan to keep on adding your own hardware the next few weeks or maybe there is some other product at your reach which could beat your hardware´s performance.
Don´t want to steal much of your precious time elaborating a long answer. Just, is there other overally worthy hardware or is yours currently still unbeatable in the short term?
When there will be a better product available it would be stupid insisting with the current one. I think that until December actual units can do their job quite well. I am starting to plan the next step, it may be a second version of the current ASIC or maybe I will find an agreement with one chipmaker and start building from there. Things are becoming more complex and I am not sure I can beat big organizations with a complete experienced staff. If other makers (for example, cointerra) will deliver something interesting, that could be the way. By acquiring chips in quantity it should allow to reach a lower price/performances than the complete product.
