size requires a year or longer, I find it quite surprising that all of that hashrate would come online in one week. It was like they flicked a single switch exactly 1 week before the
fork. Hashrate rentals are a far more parsimonious explanation for this data than actual hardware. Stacked chart version: The stacked chart indicates
that SVPool's early hashrate (Nov 1-8) came from CoinGeek directly. This is not a surprise, since CoinGeek owns and operates SVPool. They probably decided that it looked better to
have their 2.7 EH/s of hashrate split between two pools instead of all in one place. Mempool did not exist until 11-10. I suspect that CoinGeek wanted to split its
hashrate up further because they knew that a blockchain with only three pools (two of whom were owned and operated by one person) is not very reputable."
