so what's this qubic thing? it’s a blockchain focused on AI, using something it calls Useful Proof-of-Work (UPoW). people are buzzing about it since it managed to pull off an attack on Monero and now they just announced plans to do the same with Dogecoin, which is already hurting Dogecoin's price. but how are they pulling this off? In their test, Qubic claimed to have taken over 51% of Monero's mining power and did a quick reorganization of six blocks. They called it a "demonstration," but it sparked worries about a legit 51% attack, causing Monero's price to drop 6% in just one day and 16% over the week. This even led some exchanges like Kraken to pause deposits temporarily. Qubic's strategy boosted miner earnings by linking Monero rewards with QUBIC token burns, which attracted a lot of mining power. Some folks argue that Qubic didn't really attack the blockchain; they just threw a ton of cash at existing miners to do it for them. Plus, their attempt with Dogecoin might not work since it’s a tougher nut to crack compared to Monero. Honestly, I’m pretty skeptical they could pull off anything similar with Bitcoin. If they even hint at going after Bitcoin, they’ll just end up looking ridiculous, especially if their whole tactic is just throwing rewards at miners. I can't see Bitcoin miners being easily tempted to turn on the network.

What the fuck is Qubic to compete with Bitcoin? I think you need to be very conscious next when creating post like this and so it doesn't mislead readers. Qubic attacks monero and make the price to depreciate, Qubic attacks dogecoin and the price will depreciate soon and bla bla bla...now tell me what this shitcoin is capable of doing again because I still don't get why comparing it to Bitcoin lol. You can move this post to altcoins section because is totally not fit to stand along side with Bitcoin. Next time, never compare any altcoins to Bitcoin...not even Ethereum!

For all I know, they wouldn't be able to produce the hash rate that would be possible to execute the 51% attack on Bitcoin. If it was that easy, then lots of organizations would've succeeded even before now. They wouldn't try attacking Bitcoin, it's way above their league. Bitcoin Network difficulty would frustrate their efforts and they wouldn't be able to mine so much Bitcoin while they continue to compete against other miners unlike what they claim to have done with Montero.

I don't know why related topics are popping up these days about some recent developments attacking the bitcoin network, is it that those creating those thread including this one does not have a much better understanding of the bitcoin network or they feels they can join among other developers who think their innovation could serve as threat to bitcoin existence, because bitcoin network works by protocols and anything not in consensus automatically get rejected, so getting it under attack is merely impossible.

What Qubic did on the Monero chain was "selfish mining". They amassed a high amount of hashrate and tried to re-org blocks of other miners out of it. But their success was very limited, they probably weren't able to sustain a profit with this strategy. They did come close to 50% for short periods but were never able to make 50% of the blocks for extended periods (i.e. more than an hour). On Bitcoin, an attack, even if only for "selfish mining" purposes, would be much harder: - first, due to the enormous hashrate Bitcoin has, - second, because Bitcoin uses ASIC mining (SHA-256), not CPU mining like Monero -- thus amassing hashrate on XMR was "relatively" easy via botnets for example, - and third, because Bitcoin miners are very specialized, many of them are public companies. That means that they would lose a lot more if there is any damage due to an 51% attack.

As far as I know, Qubic is a type of platform or a joint smart contract, in the Qubic system there are two systems that work, namely: "transforming" and "innovative" these two different things I think there is no gap to attack bitcoin, Blockchain technology is more sophisticated and blockchain has overcome various actions that can threaten bitcoin from the first created until now. In short, Qubic is still an idea, introducing or being able to lead to services or solutions and the nature of change, meaning that they have not worked optimally, well if Qubic has the properties as I mentioned above, Of course there are two possibilities despite using a combination of Al, if it is safe to use for digital currencies and if threatening or virus means that Qubic can be destroyed or die over time, the Bitcoin network will block Qubic.

Sorry OP, I was once in your shoe thinking that something better than Bitcoin is out there, this thoughts robbed me of hundreds of dollars instead of me spending them all on Bitcoin in 2017, I would probably be a whale today or make some money from Bitcoin, I was able to get 15 Ethereum at the time among few others I ended up believing in the alts more than Bitcoin and it hurt me so bad. I can never recover from the loss because I was too brainwashed by the idea that something out there is better than Bitcoin in terms of return on the long run and also utility, I was wrong all along, I know that Qubic but it's never even close to the reliability of kaspa, not even close, forget it and focus on Bitcoin only, you won't regret it, others are pump and dumps.

You lack of understanding and research has made some people to derail, I think the op may not understand what he's actually saying may with the response he gets from here, he might be able to grab some things to add to the ones he knows thats if he's ready to learn, if I may ask whats qubic is that not bullshit, to me that's an insult to Bitcoin network, the government are finding very difficult to penetrate talk more of some shit innovation that got no ground in this space, although I understand the whole thing, anyone can come up with threads to get what's in peoples, I know the ordinarily the op might be trying to play mind games with us because he knows that we must attack the shit qubic a thing, mate i won't want to go further than this.

I don't think Qubic will be able to attack Bitcoin, because based on the information I have seen, Qubic has only demonstrated attacks against Monero, and that also seems to be just a one-sided claim from Qubic, and there hasn't been any news from the Monero community, Cmiiw. Furthermore, Qubic has a testing ethic, as they make public announcements for every move, so Monero is prepared to defend. So, I think Qubic will likely have difficulty testing Bitcoin, because I have seen Qubic still find it difficult to attack monero itself, and based on the information I have received it takes days, and there is a possibility of some interceptions against Qubic in carrying out attacks against Bitcoin ( if that happened), and this will be much more massive I think. Meanwhile, Bitcoin is still far above Monero in terms of the quantity of hashrate required. So therefore, I believe Qubic will have a very difficult time and will not be able to attack Bitcoin.

I just learnt about an hack attempt on Monero now though many believed that a 51% attack didn't occur Especially when considering the cost. I believe it's an opportunity for them to hype their token. Quibic are fundamental unit of quantum computers and there's no quantum computer currently that can hack monero Not to mention Bitcoin. So merely FUDs.

They can try creating new bitcoin pool but it's going to be much harder to compete with big bitcoin pools like FoundryUSA, Antpool ViaBTC and others. Even for monero they didn't really get over 50% of hashrate, they just faked report on one website, but they did get significant hashrate. Anyway, this qubic crap is literally worthless and I am sure they won't exist for much longer to create new attacks.

No, they are not related, even the so called attack on Monero itself have been said that it's not true at all. And with that, it could be that it was just FUD and false narrative that someone can break a chain or take over with it. Sure maybe they have all the hash rate, but I don't think that it will be enough to create a new chain. This could be just another FUD attempt by someone not just to create chaos on Bitcoin but also in Monero. So the answer is no, Qubic don't have any capacity to attack Bitcoin.

I have seen so many altcoins projects creating stupid illustration to make it looks Iike the project has the potential of making another project to have reduction in level of adoption indirectly creating a fud that could affect similar pronects. Any illustration from Qubic of making the price of monero plumate is a big fallacy and I will never take this project seriously if I am to invest in it. This is a pattern to get the heart of careless Investors that don't understand the illustration behind the Qubic getting more dominance in the market and it is seen as an attempt to confuse newbies to invest in the project.

It is funny to see someone comparing altcoins to bitcoin; is there any cryptocurrency that can be compared to bitcoin at this point? I don't think some people understand the difference between bitcoin and altcoin because if they do, they won't even create a topic about it. Bitcoin will remain the best coin ever and will continue to grow as the best cryptocurrency in the world. Qubic coin may be good with the price and have value for those who invest in it, but as far as altcoin, is still a riskier investment than Bitcoin and will never be comparable to it. Sorry for asking, but did you truly know about Bitcoin? Because if you do, you will not be comparing another coin to bitcoin, and this type of topic should not be debated. It may also confuse some newbies who are interested in bitcoin, because they will believe that there is another investment that is about to be better than Bitcoin and that they should invest in it.

From your statement alone you said it yourself that qubic offered loads of money to miners. If that is true, just imagine how much money needed to make similar attack when bitcoin's hashrate is significantly higher than monero. It's such obvious answer at this point, they definitely isn't going to waste money on doing such thing. Moreover we don't even know if monero attack is true. There are a lot of people saying that it actually didn't happen.

If Qubic’s strategy is mainly bribing miners with rewards I don’t see that working against Bitcoin. BTC miners are heavily invested in the long-term value of the network. Selling out for a short-term payout would essentially be shooting themselves in the foot. Even if Qubic made noise about targeting Bitcoin it’d likely come off as more of a publicity stunt than a real threat.
