Mining is a waste of energy. An ICO makes sense if they 1) have a product that benefits from a blockchain, 2) have a great team and a demo of their product.

  Mining doesn't waste energy, it's the cost the network pays for security, and it usefully indexes the value of the token rewarded to miners for securing the network to their cost of electricity, grounding the token value in some hard-to-manipulate real-world value.

    It wastes energy compared to POS (Proof of Stake).
    • pmorici 9y ago
      Is there a working implementation of POS yet?
      • atomical 9y ago
        It will likely happen this year with Tezos. Ethereum will eventually use POS as well.
        • pmorici 9y ago
          So, no.
          • atomical 9y ago
            Depends if you count the test nets I suppose.

  As a layman which also thinks of mining as a waste of engery (although it seems necessary as the other commenter pointed out) I hope gridcoin [0] or something similiar takes off. [0] http://www.gridcoin.us/ http://www.gridcoin.us/
