If you really want to coin to be truly decentralized it should be a multi Algorithm(so that any hardware can mine the coin) with difficulty re-targeting  ....harder difficulty for when the network gets busy... making it expensive and impracticable for corporate miners/farms to mine the coin , but mostly unaffected will be the small time miner mining from home and be rewarded more when the network slows down....

for example UIS & DGB

 ...making the Algorithm equihash is still limiting the coin to a small group of miners ...with a mutli algorithm coin ...everyone can mine it
