I have a question, when the scrypt asic come , may the doge code be patched to avoid them?
Probably not. Would require 51% of miners to switch to new PoW algorithm. Scrypt-Jane/N-factory (ala VertCoin or Microcoin) could be a replacement-- but much more difficult to configure miner. And, would need an entire network conversion. Dogecoin has had enough trouble just staying updated....
