Qubic stopped reporting their hashrate as queried and reported by https://miningpoolstats.stream/monero .

Previously, the "Unknown" pool as reported by MiningPoolStats used to be at ~3%, but now it's at ~23%, so as per silly napkin math, this tells me that Qubic could currently be in control up to 20% of the Monero network.

If the reports of depth 6 block reorgs by Qubic are true, users could consider requiring at least 5x the number of block confirmations for their incoming transactions for safety, meaning at least 30 confirmations, before they consider their incoming tokens to truly be their own.
