What somebody who achieved 700k increment on an Apple Silicion M3 can do is shut down the node on the M3, and move the node’s peer id and store to a cheaper hardware which will produce proofs slower than the M3, but still faster than if they’ve ran it from scratch on the cheaper hardware. But now they have to decide what to do with the M3: they can either start from scratch on the M3 or put the M3 out of commission. Neither option makes too much sense when we have a few days left until 2.0 when the reward formula changes, since an M3 starting from scratch will likely produce proofs slower than the 700k increment cheaper hardware, and I don’t think it’s possible to rent an M3 by the hour so they either have to pay for it until the end of the month or they’ve outright bought it.
