📝 Original message:My recent conversations with miners revealed:
* Many have made "extra-large" hardware investments recently.
* Some wonder if we have just reached (or are quickly reaching) a
plateau of hardware-efficiency. This would mean that
hardware-investments might not be made in the critical period
immediately preceding the halving.
However, some good news:
* For Chinese miners, power is often purchased in fixed quantities, for
long-durations (of around 12 months, and these contracts -fortunately-
do overlap the July halving). Because power is difficult to store, this
implies that miners will *need* to mine, at all times, even at a loss.
So miners may continue to mine after the halving, no matter what.
On the other hand, miners can default on these contracts by simply
declaring bankruptcy, at which point their equipment would be entirely
unusable, by anyone, for a very long time.
So the problem is less likely, but more potentially-catastrophic.
