This is a race against time. The enemy is at the gates, preparing for a 2nd wave of panic selling. Cavalry is on the way, but it will still take a month. Too late, I think, but the near arrival of halving should dampen the selling.
This week Raoul Pal (GMI, Real Vision) put out a report, basically telling the World is truly, royally fucked. He is bullish on gold, and ultra bullish on bitcoin. To me, the recent market activity looks a bit weak. I actually expected BTC would have hit 8400 USD already now. Gold has already fully recovered, but not bitcoin, so︀ I guess bitcoin is still very vulnerable to the downside.
Yes, if the price falls, there︄ will be more selling pressure from the miners. If it rises; less pressure. In this︅ way, the up/downtrends in bitcoin feed itself. In my opinion, the situation with hardware is︆ the same as it has always been: New mining rigs drive out the old rigs.︇ (CPU < GPU < ASIC). Somebody is always close to quitting. At that point, they︈ have only few coins left and hence don't have a huge effect on the market︉ price.
(The link you posted mentioned busting the myth, "Breakeven Price of the Miner is︊ a Price Floor." This is self-evident: In no commodity is the production cost a price︋ floor. Recent example: Crude oil market).
