So, hearing people think Bitcoin won't/can't be hurt is obnoxius at best. It does matter that the hash difficult adjusts every 2 weeks. However,there is a real issue with miners being able to pay their costs after the halving since they have mine double the BTC or the price of BTC has to double to support themselves. It doesn't matter how easy blocks get. A lot of small to medium sized miners will lose. If only big money controls the mining we are fucked.

The spreadsheet at the bottom of this post breaks the math down.
