A Quantum Money Solution to the Blockchain Scalability

Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Quantum Bitcoin (QBTC) Now Has Live Deposits

Coinegg.com has live deposits for Quantum Bitcoin.
Problem is, I don't think anyone has any idea where to find the client. Github doesn't seem to have anything.

"Don't let others move your cheese" and other unintentional hilarities from the Quantum Bitcoin page

If you're looking for some respite from the arduous task of dumping your airdrops, I suggest reading the English version of the Quantum Bitcoin fork. It's absolutely hilarious! How can anyone not be impressed by their team of "etheric fang technology researchers" and "mineral pool of experts"? Moreover, the page is full of valuable advice, such as "If you want QBTC to switch bitcoin to a candy bar, don't let others move your cheese".
(Christ, shitcoiners aren't even trying anymore. Me, I'm just gonna dump this cheese ASAP.)

Anyone Know Where to find Quantum Bitcoin Client?

I already checked github and it doesn't look like they list it on there.
Has anyone found the client for this fork?

What would happen to Bitcoin if someone suddenly invented a quantum bitcoin miner?

I imagine there's probably a team of scientists working on this right now. What would it do to bitcoin if they made a breakthrough, and suddenly started mining blocks in a fraction of a second? I know everyone was afraid of ASICs when they first came out, but this would be something completely different.
I'll be honest, I don't really know anything about quantum computing. Would it even be possible to mine a block using a quantum processor?
Thinking long-term, if someone invents a quantum hashing device sometime in the next 20 years, is Bitcoin basically game-over at that point?
Maybe we need to invent some quantum cryptography and get started on QuantumCoin.
EDIT: Whoa shit, a quantum computer might even be able to break ECDSA and deduce the private key for any public key. And there's still no mathematical proof that a regular computer can't do it with the right algorithm. You'd just be able to spend anyone's coins, which seems to be a slightly bigger problem than a 51% attack.
Well then, I don't think we should put so much trust in Bitcoin "for the long term". I feel like there's a pretty high chance that it's cryptography will be broken within the next fifty years.

Quantum computers put blockchain security at risk - Bitcoin and other cryptocurrencies will founder unless they integrate quantum technologies

This is the best tl;dr I could make, original reduced by 91%. (I'm a bot)
The solution is to develop a quantum repeater, which uses quantum teleportation and quantum optical memory to distribute entangled states between the communicating parties.
Using quantum technology for communicating as well as for the computational processing of blockchain data would further enhance security and enable blockchains to become faster and more efficient.
This step requires a 'quantum internet'10 - connecting quantum computers across a quantum communications network.
The proposed Quantum Bitcoin currency could be realized, with its security assured by the no-cloning theorem of quantum mechanics.
Such quantum 'bank notes', if they still prove necessary in future, could be made impossible to forge by containing quantum information records11.
The longer-term answer is to develop and scale up the quantum communication network and, subsequently, the quantum internet.

Unpopular opinion: Bitcoin isn´t what it claims to be

BTW I HAVE OWNED BTC IN MY LIFE ! This is not to be meant a troll. See it as an opportunity to question BTC in order to make it better eventually(?)!
The reason why I put up this post is because I see so many people on Instagram or elsewhere getting into Bitcoin as a speculative investment and thinking it is going to the moon just for some halvening.
I do not dislike the idea of cryptocurrency but actually there are a few problems with Bitcoin.

Yes, Bitcoin has paved the way for crypto, that is true.
Yes, Bitcoin is a great idea with great ideals.
Yet it is still destined to fail.

A lot of people say that BTC will be the future because of various characteristics like:

Claim #1 BTC is anonymous:
"Some effort is required to protect your privacy with Bitcoin. All Bitcoin transactions are stored publicly and permanently on the network, which means anyone can see the balance and transactions of any Bitcoin address. However, the identity of the user behind an address remains unknown until information is revealed during a purchase or in other circumstances. "
- https://bitcoin.org/en/you-need-to-know

Claim #2 BTC is decentralized:
Well, not really. BTC is tied to it´s miners. And while a lot of people here call themselves early adopters, they have never ever contributed to a solved-block. Why is this important? Who sells you your BTC? The miners... so if any big enough group of ( chinese bc they are very active) miners decides it is time to rob the people back of the BTC they sold them - there is no one going to stop them. And unfortunately this all plays along with BTC´s rules.
Everyone who didn´t get along on this one should research '51% Attack Bitcoin'\1])
The only counter I can think of is " but all the faulty transactions could be recognized and we (the hodlers) can verify the original chain on a new fork " or something like that, yeah well but technically you will still be fighting the miners and their hashrates
[1] https://duckduckgo.com/?q=51+percent+attack+bitcoin&t=ffab&atb=v140-1&ia=web

Claim #3 BTC is efficient:
If I want to send you a 100 million bucks, yeah well that can be pretty f-ing cheap in comparison to normal banks. But one of the main reasons that Bitcoins transaction fees have risen for the amounts that you actually want to use daily , is because it is more profitable for miners\1])
So as more people adopt and thus transactions getting more profitable for the miners, fees are gonna rise..
-
Also in term of energy consumption. A SINGLE transaction needs as much power as an entire US-household uses in an avg 23 days\3]) That is not sustainable, as the consumption grows with adoption. Even with 100% renewable power( which we are far away from) the shere amount of ressources (e.g silicon for solar-panels for "neutral" energy) is very debatable. Also the mining hardware has to be changed with every halvening (press f for all these rare metals in computer parts)

#4 Thought: Quantum Computing
What will you do with Bitcoin if Google or IBM (or others) get their quantum computers to work so good, that they will easily decrypt bitcoins encryption.
Here is an interesting video if you are interested in how QComputing threatens basically anything that is encrypted:
https://www.youtube.com/watch?v=6H_9l9N3IXU

#5 Thought: Comparing BTC to USD
To anybody who says "look at the dollar dying, we will go to 100,000$ soon" - you are most likely speculating instead of believing in the intrinsic value of BTC (proof of work). If you keep measuring BTC worth in any fiat currency, you lost the point. If it really becomes THE currency, any comparison to fiat is obsolete.
I know this one is kinda unsolid but I wanted to throw it in!

#6 Thought: Financial Elite
Bitcoin rewards those who adopt first. Sounds good, right? If fiat and governments fail, most of you will be the top 1% while holding 90% of the BTC in circulation. Will that be any better than the monetary system we have right now? In the end Bitcoiin will not serve the many, who have little but it will serve the few who have much.
Think about your fellow (billions of) humans around the world. Will you explain to them: ' Well I got in first, so I am entiteled to be rich' ? I think if BTC would actually become widely adopted, that is an ethical question a lot of people have to ask themselves!
Tbh, this might be the most important point for me and I am SUPER excited for your opinions on that!

TL:DR I think there are good reasons why BTC is (unfortunately) wishful thinking and other cryptos with hopefully better systems will take lead.

I would love to hear good arguments against my positions because mostly people get triggered instead of having a conversation that could benefit everybody!

Bitcoin firme em $10k, Atlas Quantum não comprova existência de robô e mais! Bitcoin News 2020 Bitcoin Q&A: Migrating to post-quantum cryptography Bitcoin Q&A: Will Quantum Computing Destroy Bitcoin? Quantum Computing  The Biggest Threat to Bitcoin?? (Must Watch)

The unique Bitcoin tool set with numerous and useful features. Suitable for learning and testing. As long as multiple users have access to a quantum computer, no single quantum computer will gain dominance over Bitcoin mining. Alternative proof-of-work mining schemes can also prevent quantum dominance, and some studies have found that ASIC devices, which are already faster than normal computers, can reduce the quantum advantage over mining. Honeywell’s new quantum computer edges closer to threatening Bitcoin. Honeywell has announced that its newest quantum computer has reached a quantum volume of 64—twice that of IBM and Google’s rival machines. Andrea Coladangelo and Or Sattath, Quantum 4, 297 (2020). We put forward the idea that classical blockchains and smart contracts are potentially useful primitives not only for classical cryptography, but for quantum cryptography as well. Abstractly… The problem isn’t really Bitcoin. If we get quantum computers that can do thousands of qubits without a correction and consistent results, we have a much bigger problem. The bigger problem we have is that the entire world’s classified communications, confidential communications, financial systems etc, all depend on cryptography today.
