Is Crypto Currency truly at risk due to Quantum Computers, and what can you do about it? Posted: 02 Feb 2018 03:52 PM PST Is Crypto Currency truly at risk due to Quantum Computers, and what can you do about it?There is no denying that the Quantum revolution is coming. Security protocols for the internet, banking, telecommunications, etc... are all at risk, and your Bitcoins (and alt-cryptos) are next! This article is not really about quantum computers[i], but, rather, how they will affect the future of cryptocurrency, and what steps a smart investor will take. Since this is a complicated subject, my intention is to provide just enough relevant information without being too "techy." The Quantum EvolutionIn 1982, Nobel winning physicist, Richard Feynman, hypothesized how quantum computers[ii] would be used in modern life. Just one year later, Apple released the "Apple Lisa"[iii] – a home computer with a 7.89MHz processor and a whopping 5MB hard drive, and, if you enjoy nostalgia, it used 5.25in floppy disks. Today, we walk around with portable devices that are thousands of times more powerful, and, yet, our modern day computers still work in a simple manner, with simple math, and simple operators[iv]. They now just do it so fast and efficient that we forget what's happening behind the scenes. No doubt, the human race is accelerating at a remarkable speed, and we've become obsessed with quantifying everything - from the everyday details of life to the entire universe[v]. Not only do we know how to precisely measure elementary particles, we also know how to control their actions! Yet, even with all this advancement, modern computers cannot "crack" cryptocurrencies without the use of a great deal more computing power, and since it's more than the planet can currently supply, it could take millions, if not billions, of years. However, what current computers can't do, quantum computers can! So, how can something that was conceptualized in the 1980's, and, as of yet, has no practical application, compromise cryptocurrencies and take over Bitcoin? To best answer this question, let's begin by looking at a bitcoin address. What exactly is a Bitcoin address?Well, in layman terms, a Bitcoin address is used to send and receive Bitcoins, and looking a bit closer (excuse the pun), it has two parts:[vi] A public key that is openly shared with the world to accept payments. A private key that is derived from the public key. The private key is made up of 256 bits of information in a (hopefully) random order. This 256 bit code is 64 characters long (in the range of 0-9/a-f) and further compressed into a 52 character code (using RIPEMD-160). NOTE: Although many people talk about Bitcoin encryption, Bitcoin does not use Encryption. Instead, Bitcoin uses a hashing algorithm (for more info, please see endnote below[vii]). Now, back to understanding the private key: The Bitcoin address "1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm" translates to a private key of "5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAnchuDf" which further translates to a 256 bit private key of "0000000000000000000000000000000000000000000000000000000000000001" (this should go without saying, but do not use this address/private key because it was compromised long ago.) Although there are a few more calculations that go behind the scenes, these are the most relevant details. Now, to access a Bitcoin address, you first need the private key, and from this private key, the public key is derived. With current computers, it's classically impractical to attempt to find a private key based on a public key. Simply put, you need the private key to know the public key. However, it has already been theorized (and technically proven) that due to private key compression, multiple private keys can be used to access the same public key (aka address). This means that your Bitcoin address has multiple private keys associated with it, and, if someone accidentally discovers or "cracks" any one of those private keys, they have access to all the funds in that specific address. There is even a pool of a few dedicated people hunting for these potential overlaps[viii], and they are, in fact, getting very efficient at it. The creator of the pool also has a website listing every possible Bitcoin private key/address in existence[ix], and, as of this writing, the pool averages 204 trillion keys per day! But wait! Before you get scared and start panic selling, the probability of finding a Bitcoin address containing funds (or even being used) is highly unlikely – nevertheless, still possible! However, the more Bitcoin users, the more likely a "collision" (finding overlapping private/public key pairs)! You see, the security of a Bitcoin address is simply based on large numbers! How large? Well, according to my math, 1.157920892373x1077 potential private keys exist (that number represents over 9,500 digits in length! For some perspective, this entire article contains just over 14,000 characters. Therefore, the total number of Bitcoin addresses is so great that the probability of finding an active address with funds is infinitesimal. So, how do Quantum Computers present a threat?At this point, you might be thinking, "How can a quantum computer defeat this overwhelming number of possibilities?" Well, to put it simple; Superposition and Entanglement[x]. Superposition allows a quantum bit (qbit) to be in multiple states at the same time. Entanglement allows an observer to know the measurement of a particle in any location in the universe. If you have ever heard Einstein's quote, "Spooky Action at a Distance," he was talking about Entanglement! To give you an idea of how this works, imagine how efficient you would be if you could make your coffee, drive your car, and walk your dog all at the same time, while also knowing the temperature of your coffee before drinking, the current maintenance requirements for your car, and even what your dog is thinking! In a nutshell, quantum computers have the ability to process and analyze countless bits of information simultaneously – and so fast, and in such a different way, that no human mind can comprehend! At this stage, it is estimated that the Bitcoin address hash algorithm will be defeated by quantum computers before 2028 (and quite possibly much sooner)! The NSA has even stated that the SHA256 hash algorithm (the same hash algorithm that Bitcoin uses) is no longer considered secure, and, as a result, the NSA has now moved to new hashing techniques, and that was in 2016! Prior to that, in 2014, the NSA also invested a large amount of money in a research program called "Penetrating Hard Targets project"[xi] which was used for further Quantum Computer study and how to break "strong encryption and hashing algorithms." Does NSA know something they're not saying or are they just preemptively preparing? Nonetheless, before long, we will be in a post-quantum cryptography world where quantum computers can crack crypto addresses and take all the funds in any wallet. What are Bitcoin core developers doing about this threat?Well, as of now, absolutely nothing. Quantum computers are not considered a threat by Bitcoin developers nor by most of the crypto-community. I'm sure when the time comes, Bitcoin core developers will implement a new cryptographic algorithm that all future addresses/transactions will utilize. However, will this happen before post-quantum cryptography[xii]? Moreover, even after new cryptographic implementation, what about all the old addresses? Well, if your address has been actively used on the network (sending funds), it will be in imminent danger of a quantum attack. Therefore, everyone who is holding funds in an old address will need to send their funds to a new address (using a quantum safe crypto-format). If you think network congestion is a problem now, just wait… Additionally, there is the potential that the transition to a new hashing algorithm will require a hard fork (a soft fork may also suffice), and this could result in a serious problem because there should not be multiple copies of the same blockchain/ledger. If one fork gets attacked, the address on the other fork is also compromised. As a side-note, the blockchain Nebulas[xiii] will have the ability to modify the base blockchain software without any forks. This includes adding new and more secure hashing algorithms over time! Nebulas is due to be released in 2018. Who would want to attack Bitcoin?Bitcoin and cryptocurrency represent a threat to the controlling financial system of our modern economy. Entire countries have outright banned cryptocurrency[xiv] and even arrested people[xv], and while discrediting it, some countries are copying cryptocurrency to use (and control) in their economy[xvi]! Furthermore, Visa[xvii], Mastercard[xviii], Discover[xix], and most banks act like they want nothing to do with cryptocurrency, all the while seeing the potential of blockchain technology and developing their own[xx]. Just like any disruptive technology, Bitcoin and cryptocurrencies have their fair share of enemies! As of now, quantum computers are being developed by some of the largest companies in the world, as well as private government agencies. No doubt, we will see a post-quantum cryptography world sooner than most realize. By that point, who knows how long "3 letter agencies" will have been using quantum technology - and what they'll be capable of! What can we do to protect ourselves today?Of course, the best option is to start looking at how Bitcoin can implement new cryptographic features immediately, but it will take time, and we have seen how slow the process can be just for scaling[xxi]. The other thing we can do is use a Bitcoin address only once for outgoing transactions. When quantum computers attack Bitcoin (and other crypto currencies), their first target will be addresses that have outgoing transactions on the blockchain that contain funds. This is due to the fact that when computers first attempt to crack a Bitcoin address, the starting point is when a transaction becomes public. In other words, when the transaction is first signed – a signed transaction is a digital signature derived from the private key, and it validates the transaction on the network. Compared to classical computers, quantum computers can exponentially extrapolate this information. Initially, Bitcoin Core Software might provide some level of protection because it only uses an address once, and then sends the remaining balance (if any) to another address in your keypool. However, third party Bitcoin wallets can and do use an address multiple times for outgoing transactions. For instance, this could be a big problem for users that accept donations (if they don't update their donation address every time they remove funds). The biggest downside to Bitcoin Core Software is the amount of hard-drive space required, as well as diligently retaining an up-to-date copy of the entire blockchain ledger. Nonetheless, as quantum computers evolve, they will inevitably render SHA256 vulnerable, and although this will be one of the first hash algorithms cracked by quantum computers, it won't be the last! Are any cryptocurrencies planning for the post-quantum cryptography world?Yes, indeed, there are! Here is a short list of ones you may want to know more about:
Full disclosure:Although I am in no way associated with any project listed above, I do hold coins in all as well as Bitcoin, Litecoin and many others. The thoughts above are based on my personal research, but I make no claims to being a quantum scientist or cryptographer. So, don't take my word for anything. Instead, do your own research and draw your own conclusions. I've included many references below, but there are many more to explore. In conclusion, the intention of this article is not to create fear or panic, nor any other negative effects. It is simply to educate. If you see an error in any of my statements, please, politely, let me know, and I will do my best to update the error. Thanks for reading!

Posted: 02 Feb 2018 11:11 AM PST I think this general sentiment will help people's mentality not only today, when it feels like the market will end up at zero, but the next time it goes on a bull run. The reason people buy as the price is rising is because they're afraid it will keep rising forever. But any stable market, be it a stock market or a crypto market, will experience periods of rise followed by periods of recessions. When the price is going up, know it likely won't go up forever. And when the price is falling to the floor, know it likely won't fall forever. To me, this mentality is more important than HODL. The problem with HODLing, in my opinion, is it prevents you from ever accepting financial gains, which is the whole point of investing. When the market rises, if you've made any profit, you should sell some and be satisfied. But subsequently, when the market crashes, as it is crashing hard currently, it is prudent to remember two things. Firstly, if you are willing to cash out a portion of your gains prematurely, it's an insurance policy against fearfully cashing out your losses when the market declines. But secondly, this is a game of odds. Yes, history repeats itself until it doesn't, and it is within the realm of possibility that the CryptoCurrency market will completely implode on itself. But more likely, this is a period of recession that will be followed by a period of gain. Market volatility is actually a sign of a generally stable market (just ask stock brokers). So don't panic today, but remember this feeling the next time your portfolio is showing massive profitability, and don't forget to keep cashing out portions of your investment. There is of course a value to HODL'ing something. But in my eyes, it's rather foolish to always HODL everything. Because best case scenario, if you sell a portion when it rises, you can always use a portion of what you sold to buy back in at a later date, and worst case scenario you end up with the lesser of two profits! Better to sell early in the green than panic sell in the red. Because in all likelihood, it won't rise forever, and it won't fall forever. [link] [comments] | ||
Posted: 02 Feb 2018 07:37 PM PST A major issue that is shaking off too many hands off of wonderful investments is the fact that all their usd values are derived from bitcoin's price. So if bitcoin goes up, so do all the others, and same if it goes down. When an average investor looks at their portfolio and see that they're 25% down in USD of their investment, it definitely can persuade him to liquidate his position to not lose more, dropping both the coin/btc pair and btc/usd price together as they panic sell to fiat, thus recurring the cycle. Alts must find a solution to find a new host that represents their performance whether it be a new coin that has zero volatility. [link] [comments] | ||
To everyone thinking “I could have made so much money if I just sold” Posted: 02 Feb 2018 05:00 PM PST No. 1) you would have sold before or after the ATH, but for sure not at it 2) you would probably have rebought long ago, still far above today's values 3) you probably wouldn't have set the money aside for the taxes Don't lie to yourself and don't live in illusions Edit: Some seem to misunderstand me, I don't mean to sound condescending. What I mean is: Most of the 'if I had just sold at point x' just come from knowledge you didn't have at that point. What would have made you selling back then? And the danger would have been, that if you sold for good profit, you'd have rebought while it started plumetting, as you might have thought 'well, it's so low now, let's make some more profit, it can just go up from here', while it was still on the way down. You'd still have lost a lot of money, but I guess a lot of people wouldn't have set the money for the taxes aside, trying 'one last gamble' with that money. And then they'd be forced to sell with huge losses to be able to pay those taxes, and wouldn't even have the option of holding. In my country, if I sell for profit within a year of buying, I'd have to pay 50% of the profit as tax. added "probably at two points" [link] [comments] | ||

The only numbers that matter... Posted: 02 Feb 2018 08:28 PM PST In a recent poll, based on their findings, only 5% of Americans own Bitcoin. America is the 2nd largest Bitcoin market. Today there was 2.5 billion in USD volume in Bitcoin. Your altcoins don't even register. The 3rd biggest market in terms of fiat trading is Korea. The 4th is the Euro - There was 450M Euro traded today. That's a fifth of the US market. There are over 500 million in Europe, 70% MORE than America. Yet the volume is one fifth of the US. And then there's GBP. There was 20 million in GBP exchanged today. 20 MILLION! That's 1 percent of the US volume. You are involved in something that very few people understand, know about, and much less own. Go sit down. If you sell now You are selling real estate in the 1900s, Go sit down.

You heard it here first: The correction is over Posted: 02 Feb 2018 12:00 PM PST As I managed to buy all of the bigger corrections since May 2017, and always just 10%-15% above the bottom, I thought I would put together a little "bottom-guide" (sounds hot) for you. The following are the indicators that a bottom is in. Keep them in mind for the next time: Price: All the coins double-digit in the red. If you know a bit about technical targets, that knowledge is helpful as well. In the current correction, the savvy traders knew that $8,000 was the target. We got around $7,600 in the end. Strong Bounce: You want to look for an ultimate sharp fall that washes out the last weak hands; and then an immediate strong rebound. The first part was a bit atypical this time, as we didn't get that steep last part of the fall; maybe because the bears were completely exhausted (all the weak hands washed out already). We saw the steep initial rise though from $7,600 to $8,400 or so. You want to look for something like a 10% rise there, and this is exactly what we got. Sentiment: Read the posts on reddit, and also on bitcointalk, and remember the overall feeling: This is what a bottom looks like. Many desperate people, many people projecting the current trends (downside) into the future, which the human mind always tends to do. And even the experienced people sound a bit down; they are not thinking about selling, but they are getting ready to wait for a long time till it goes up again. Remember this sentiment and recognize it next time around! Volume and shorts: Two more important indicators, although I haven't been watching them lately. Look for high volumes at the turning points, and look for way more futures shorts than longs. That means the market has become very pessimistic - which is always a bullish sign. With a bit of experience, it becomes quite obvious when the bottom is in. Look at these signs, and you can profit from buying low. PS: Obviously, this is just my personal opinion. Make up your own mind, nobody has a crystal ball. [link] [comments] | ||
