At some point, when the difficulty rises to a level that even the Avalon chips will have a hard time earning for the Avalon miners, of what use is your expensive Avalon mining equipment?
I am looking into the possibility of using the chips to mine for
PPCoins. This crypto-currency uses the same hashing algorithm as Bitcoin. In fact, it is derived from Bitcoin source code.
For those who bought Avalon systems, I believe this repurposing would require reprogramming the Spartan-6 Control Unit. Other than this, I don't see any other changes that would be required.
What do you think?
