PoC3, why should a miner spend all his Inernet traffic ?

  • I kbow its far in the future. Perhaps end 2019 or 2020 but when i think of PoC3 I am asking me some questiongs.

    Why should a miner store PoC3 data. That would take all his traffic from his internet connection and the speed goes down ?

    Why should someone store his content in PoC3 ?
