X13 - Domination by Mining Farms operations

PoW Phase: 3-4 months
Yes, any of those 'X' algorithms are dominated by huge mining farms. What about a coin base like Myraid coin? We'll have the option to mine Scrypt, SHA256D, Qubit, Skein or Myriad-Groestl.
How it works
Each proof of work algorithm has its own independent difficulty.
Any algorithm can find the next block.
All the algorithms use the same difficulty adjustment method.
On average, each algorithm has the same chance of finding the next block.
Each algorithm aims for a block generation time of 2.5 minutes.
Over the five algorithms, a block should be found on average every 30 seconds.
