As stated before, the direct sales of old blades' price difference is not part of the compensation. And for new blades we only ship to resellers in most of the areas.

The new blades (as well as later products) turned out to be incompatible to the upgrading we mentioned, so what we could and would do is just distributing new products at very low or zero price to auction/earliest purchasers with the number based on the purchased amount and the whole network hashrate increase.
