This would mean that&#xA;hardware-investments might not be made in the critical period&#xA;immediately preceding the halving.&#xA;&#xA;However, some good news:&#xA;&#xA;* For Chinese miners, power is often purchased in fixed quantities, for&#xA;long-durations (of around 12 months, and these contracts -fortunately-&#xA;do overlap the July halving). Because power is difficult to store, this&#xA;implies that miners will *need* to mine, at all times, even at a loss.&#xA;So miners may continue to mine after the halving, no matter what.&#xA;&#xA;On the other hand, miners can default on these contracts by simply&#xA;declaring bankruptcy, at which point their equipment would be entirely&#xA;unusable, by anyone, for a very long time.&#xA;&#xA;So the problem is less likely, but more potentially-catastrophic.&#xA;&#xA;Paul&#xA;&#xA;On 3/2/2016 8:06 PM, Paul Sztorc wrote:&#xA;&gt;&#xA;&gt; On 3/2/2016 12:53 PM, Gregory Maxwell via bitcoin-dev wrote:&#xA;&gt;&gt; What you are proposing makes sense only if it was believed that a very&#xA;&gt;&gt; large difficulty drop would be very likely.&#xA;&gt;&gt;&#xA;&gt;&gt; This appears to be almost certainly untrue-- consider-- look how long&#xA;&gt;&gt; ago since hashrate was 50% of what it is now, or 25% of what it is&#xA;&gt;&gt; now-- this is strong evidence that supermajority of the hashrate is&#xA;&gt;&gt; equipment with state of the art power efficiency.&#xA;&gt; I don&#39;t understand the relevance of this.&#xA;&gt;&#xA;&gt; In my view, we would prefer miners to invest in hardware just a mere&#xA;&gt; 2016 blocks away from the halving. Instead, they&#39;ve made them too soon.&#xA;&gt; Assuming that miners are already located in low-power-cost areas, the&#xA;&gt; difficulty will be quickly rising to compensate for &#34;state of the art&#xA;&gt; power efficiency&#34;.&#xA;&gt;&#xA;&gt; So it will have canceled out by July.&#xA;&gt;&#xA;&gt; If anything, the more efficient miners become today, the bigger our&#xA;&gt; potential problem in July, because chip-manufacturers may have used up&#xA;&gt; all of the easy efficiency-increasing moves, such that investments do&#xA;&gt; not take place in June.&#xA;&gt;&#xA;&gt; Paul</html></oembed>
