If Monero Can Suffer 50% Hashrate Risk, Why Can't Bitcoin?

[TastyChillySauce00]

Update - Monero (XMR) deposits have been re-enabled and now require 720 confirmations before crediting. 
Given the current uncertainty around the security of the Monero network due to major hash rate consolidation under a single entity, Kraken may halt deposits at any time and delay crediting at its discretion.

720 confirmations?! 😳 That sounds like forever! 

And yet… withdrawals are still allowed?? That’s wild. Seems crazy strict on deposits but somehow you can still send your XMR out. 

Honestly, the whole thing makes me wonder — if something like this happened to Bitcoin, the panic would be off the charts. 

They are an exchange and just trying to make sure they got the money confirmed for real. After all the more confirmation the more secure it is.

The same way they are handling new L1 and L2 and even XMR with 720 confirmation is moderate requirement, some L1 out there requires thousands of confirmation.
But I bet this massive confirmation requirements only happen in kraken.

Thanks for your response. I respect that you linked some sources, but I’ll stick with the ones that convinced me otherwise:  

1. Kraken halts Monero deposits, citing Qubic seizing 51% hashrate  
2. Cryptodnes: Kraken suspends Monero deposits after 51% attack linked to Qubic Pool  

Come on, look at the content of the links you just shared. No research, just copy and paste reporting with no actual facts, but it's unfortunate you also decided to believe the lies instead of reading everything else sent out to you.

For me, the fact that a major exchange like Kraken reacted the way it did is enough to take the 51% narrative seriously.

 
Continue religiously believing them. We can't really force you to see the light if you don't want to.

And regarding LoyceV — I know he didn’t bother to reply directly, since he agreed with your post and simply merited it as a “carbon copy” of his thoughts. That’s fine, but I’ll admit I’m curious: what does it take to earn a merit from Loyce himself? 🙂

You need some merits or what?

That is not a good excuse.

It is not a moderate requirement, don't speak nonsense. In one sentence you say that the requirement is moderate and in another that it is massive. Many L1s have 1-2 second block time, to require thousands of confirmations is very fast although I have not seen anywhere a requirement of thousands of confirmations. Monero has a block time of 2 minutes. 720 confirmations is 1440 minutes or 24 hours. That is completely insane.

It is clear that he opened this thread just to farm some merit, he does not care about Monero neither does he know much about Monero or Bitcoin. If he was really interested in the topic, he would have done his research instead.

@BitHodlers 

Since you seem so confident in your critique… maybe you can explain how the RandomX algorithm works? 

If you don’t know or have to look it up, then it’s clear we’re on roughly the same page — clueless together. 😉

CEX do this to manage risk, ETC deposit was required to have 5k-10k confirmation post 51% attack. They see the 51% attack rumour as a threat and treat it as one. They aren't giving a chance to any loss that might occur by prematurely crediting money from a blockchain that's rumoured to be having 51% attack recently.

The L1 that requires 1-2 confirmation are L1 that's confirmed to be secure, highly decentralized, and trusted just like bitcoin, solana, and ethereum.
The lower bracket L1 usually have hundreds of confirmation. It's just the truth. Even more so after the blockchain experiences attack. It's what makes XMR different compared to BTC. XMR isn't as resilient as BTC.

Nothing that you wrote disproves my point though? 24 hours is completely insane. You think it is not because you don't understand fully how a 51% attack works, its impacts and the rate of orphans. For someone to be able to orphan a whole 24 hours worth of blocks, the attack would have to be on a scale where we could start saying goodbye to the Monero as we know it today.

Instead other services increased confirmation times much more conservatively. It is just this CEX that did it in this crazy amount.
