I don't completely understand the situation, so somebody with better knowledge please chime in. Long story short, if you mine Monero in Qubic's pool, you get 3 times the return, this attracts miners. But this also costs money for the Qubic people, so they can't just keep this attack/attraction going on forever. They are also facing a halving in a week. The situation is fluid. I always liked Monero because it is actually anonymous, unlike BTC. "Let's talk about why they were able to mine the majority of blocks despite not having the majority of hashrate. Qubic was using a technique called "selfish mining", which is basically a technique that temporarily hides your mined blocks from the rest of the network in order to gain a competitive advantage. Using this strategy, you can mine a lot higher percentage of blocks than you could by mining fairly. This is how they were able to mine the majority of blocks for a period during their previous "mining marathon" despite not having the majority of the network's hashrate." "Qubic shills keep spamming that they now have 51% of the network in their palm, and that miners need to switch over now to avoid losing money. But the reason they're so desperate for miners is switch is precisely because they don't have 51% of the network's hashpower, but want to have it in time for the attack." "This attempted attack is not sustainable. Qubic is burning a lot of money on this, and it has a halving in just over a week from now, which will cripple its ability to keep payrolling it. That doesn't mean we'll be out of the woods, but they're currently at the height of their power, which is why they're so desperate to pull off an attack in time. They weren't even able to maintain their selfish mining! During their most recent "Monero mining marathon", the one where they claim they achieved 51% of hashrate, they actually only mined about 36% of blocks total."
