The Quantum Computing Threat

So, Vitalik Buterin recently brought up the potential danger posed by quantum computers coming up in the next few years. "Q-Day" isn’t right around the corner, but in a couple of decades, we could be facing some serious issues. This raises a pretty important question: Should we consider investing in coins that already offer some protection against quantum computing threats? If there's even one solid news report about a quantum computer that can actually break classical cryptography, it’s likely that a bunch of new investors and possibly even whales will jump into these coins. Some of their prices could easily soar several times over, driven by fear, hype, and the urge to safeguard investments or score quick profits. After digging around a bit, I found some coins that are connected (to varying extents) to quantum resistance: A quick look at quantum-related projects: Quantum Resistant Ledger (QRL) This one was developed from the ground up to be quantum-resistant. Quantum protection is at the heart of the project, not just some future promise. Algorand (ALGO) A big player in the blockchain space that’s making actual moves towards post-quantum (PQ) cryptography in certain areas. But the entire ecosystem isn’t fully PQ-secure yet. QANplatform (QANX) They’re really pushing the PQ narrative and claim to have a post-quantum design. The big question is how much of that is actually operational and how much is still just an idea. Cellframe (CELL) This project is tailored specifically for a post-quantum world. It employs PQ algorithms at both the protocol and infrastructure levels. Main downside: it’s a niche project, so gaining traction might take some time. Naoris Protocol (NAORIS) This one is more about cybersecurity.

We are still years ahead from Quantum computing which is ample of time for majority of all blockchain projects to become quantum resistant. This is why I'm not too worried over the threat that Quantum computing poses because I have the believe that we we'll have solutions to counter it pre-quantum and post-quantum computing era. Even Bitcoin too should be quantum resistant in the not-so-distant future.

No. Changing a coin to be quantum resistant isn't rocket science, like you already pointed out that there are several of them. If it would be a hard issue to code, there wouldn't be countless of quantum resistant coins, which many of them have died already btw. This is not an issue that's happening any time soon, so it's not on top of the list that anyone should focus on. And when time comes to act, it won't take for ages to fix. Planning for it makes more sense then buying some snake-oil coins from worry troll devs.

Just because a coin is quantum resistant, doesn't automatically make them good investment nor a legit investment. These coins you mentioned scream shitcoins to me. In the future, a big coin like ethereum could always implement quantum resistant cryptography and ethereum is far better investment than any of these coins you mentioned. A coin can have quantum resistance already built-in but if nobody uses it and nobody even know that coin even exist. What's the use? feels like a waste of technology.

Yes, it may not be actual right now. I believe that Ethereum and BTC will implement protection against quantum computers, but by that time the price may not allow people with a low balance to earn much money. I want to know if there are a few coins that could significantly exaggerate investments in advance. (To invest a small amount and forget it for the long term).

You are right, most of those coins are speculative, and Ethereum is much better for a safer investment. But my point is about the coins that will be popular at that “scarier” time, when most people will buy those shitcoins. The question is whether there are coins that are worth at least a $100 investment to hold for 10 years.

What's the reasoning behind people waiting and not investing until big coins implement that protection? What does the price of large market cap currencies have anything to do with this quantum computer? If you rather just play with small market cap coins, that's perfectly understandable, but why wouldn't you choose them for prioritizing innovative cutting edge technologies, rather than that quantum protection copy paste idea. Which like i said, isn't too innovative or hard to implement for any other coin.

It doesn't, it's probably just a hype thing that's pushing people into his narrative of which coin people should buy. It make sense about the threat but remember that in the age of internet, nothing is guaranteed safe even with these projects that have so much protection for that kind of attack. Don't be so too confident that all of the mentioned projects are 100% safe and protected. Because attackers are upgrading, whichever attack and threat they use to any of them when there's a loophole being abused and found, they'll be able to successfully penetrate these chains.

Investing in altcoins is not something you should rely on because of how easy they can crash at any time the dev of the project start fucking up or trying to be greedy. I don't know what coin that will still be in existence in 10 years time. I believe that the era of cryptocurrency is here and we might starts seeing a different trend that can make most of the projects we know now to start fading away and investors looking for a better alternative coin to hold so that they don't have to lose money due to change in trend.

No, it doesnt.  The claim that these coins offer "quantum security" is simply a gimmick designed to attract ignorant investors such as you.  In addition, when quantum computers pose a legitimate risk to our digital stores of value (such as BTC or ETH), all of the major cryptocurrency platforms will implement post-quantum cryptographic solutions via hard or soft forks.  The idea that you need to invest in a "special" crypto cion right now to protect yourself from quantum computing 10-15 years down the line is comical at best.  There is no chance that the cryptocurrency that you buy today will have any real use or value by the time quantum computers are able to break into your wallet.

In crypto land, this has been a subject that's been debated for years. Vitalik brought up his concerns on ETH, but Bitcoin and other cryptos are also at risk. Some projects went a step further by adopting Quantum-resistant protocols beforehand. I'd say they are way ahead of the game. Quantum Computing may not be a threat right now, but it will be in the future. Better be prepared for the worst, just in case. I'm sure developers of popular cryptocurrencies already have it figured out. Bitcoin in its current form, is Quantum-resistant. But adding Lamport Signatures or a similar technique/protocol would add even more security against the potential threat of QC attacks. If Quantum computers can successfully "crack" Bitcoin and its variants, then banks and governments would be doomed. To answer your question, I don't think it makes sense to invest in QC-ready cryptocurrencies when QC attacks aren't even a threat these days. The coins you've mentioned are barely popular on the market. I'd stay with BTC and ETH instead. But to each, their own.

Even at scarier time I doubt that, there may be a spike or temporary hype but they are nowhere at the level of Ethereum in liquidity and utility. Buying them is meaningless because what are they gonna use it for? if you just want to try your luck, then sure. Moreover, these quantum resistant coin haven't proven it yet. The good thing is that Vitalik Buterin acknowledge this risk and hopefully come up with a solution. A solution that can be adopted by other blockchain as well. At least we're still safe for now .
