321  Economy / Economics / Re: How did the Bakkt launch go? Quick recap on: October 04, 2019, 02:09:21 AM
It flopped, signaling that retail investors might not be too interested in Bitcoin after all, contrary to past reports. Binance and JPMorgan both think that the flop was a contributing factor towards the price drop.

Both Bakkt and the market got rekkt, and I doubt either party wanted this outcome.

323  Bitcoin / Bitcoin Discussion / Re: Hong Kong Bitcoin Trading Volume Spikes to Highest Levels Ever Recorded on: October 03, 2019, 03:59:44 AM
It's not a lot of volume if you just process the numbers of HK, but if you bundle all the countries going through economical/political turmoil, the volumes suddenly aren't that bad at all. In fact, this is only the start. I expect that the situation will be much worse in the forthcoming years, which will only drive Bitcoin adoption to the next level in these countries.

Are you referring to a specific figure? Would you mind sharing it? Local unrest does seem to affect volumes positively, but not in any significant degrees from what I've seen, even in these extreme cases.

Hong Kong can become a very important place for crypto, and can affect its price

They can prove that Bitcoin can help with anonymity for matters involving the protests, but affecting global prices is a long shot considering their currency isn't really at risk:

The Hong Kong Monetary Authority (HKMA), the city’s de-facto central bank, buys local dollars if it gets too weak and sells to curb excessive strength.

It has plenty of firepower, with $448.5 billion of assets in its foreign exchange fund alone as of July, representing roughly seven times the currency in circulation, according to HKMA.

Getting rid of their HKD isn't a pressing matter at the moment.
324  Bitcoin / Bitcoin Discussion / Re: If you think Bitcoin is the world's most widely used cryptocurrency,you're wrong on: October 03, 2019, 02:20:35 AM
With Tether’s monthly trading volume about 18% higher than that of Bitcoin, it’s arguably the most important coin in the crypto ecosystem. Tether’s also one of the main reasons why regulators regard cryptocurrencies with a wary eye, and have put the breaks on crypto exchange-traded funds amid concern of market manipulation.

Ignoring the half-truth tidbit used by the article as clickbait, I would actually argue that Tether isn't all that important for the crypto ecosystem. It's true that the role it plays is vital to crypto trading, but it's also disposable in that there are a lot of other stablecoins that can take its place should it collapse. Sure Tether collapsing would be a big deal, but Bitcoin collapsing would mean the end of crypto as we know it; which is the most important coin in the crypto ecosystem now?
325  Bitcoin / Bitcoin Discussion / Re: A bitcoin Mining Farm burned down at the same time as a 119 min Block time! on: October 02, 2019, 08:40:19 AM
Update: the alleged owner of the burnt mining farm just spoke out:

In the last couple of days,a rumor is circulating about a fire in alleged Innosilicon farm causing ten million dollars miner equipment loss. We can say with 100% certainty that the fire was not related to Innosilicon and there has been ZERO Innosilicon property or equipment loss.

So either it didn't happen at all, or it was misidentified. It's looking to me like the original source of the video just wants attention, considering he didn't even say where he got it in the first place.
326  Bitcoin / Press / Re: [2019-09-29] A Dangerous Bug in Bitcoin’s Lightning Network Has Been Fixed on: October 02, 2019, 07:54:50 AM
There are a lot of people who are rooting for Bitcoin to fail, and I wouldn't put it past them to lie about losing money.

I expected Roger to be super loud about it everywhere on social media, but it seems that it has gone past him, or he has paid sockpuppets to do the work for him now he has to maintain a more serious image as head of an exchange.

There were plenty of threads about it in r/btc the past few days, and the Bitcoin.com article reporting it actually claims that the bug was exploited at least once, but without evidence:

...although conclusive evidence did show that at least one exploitation of the bug did occur “in the wild” on September 7.

So yeah, they probably did try to make it a bigger deal than it is.
327  Bitcoin / Bitcoin Discussion / Re: A bitcoin Mining Farm burned down at the same time as a 119 min Block time! on: October 01, 2019, 08:21:04 AM
note that the drop that charts showed was due to a mistake in their calculation and was not real. you can see how it bounced back up.

It's not actually a mistake in calculation, but the actual calculation itself being imperfect in the first place:

The model assumes that blocks are created every 10 minutes on average. But if blocks happen to be found more quickly or slowly than this—purely by random chance, not by a change of hashrate—this could alter the estimated hashrate. So, if miners continually faced bad luck, and blocks happened to take longer, it would appear as if the hashrate dropped off a cliff.

I'm not sure if the fire actually happened due to the lack of sources, but since blocks are being found normally again, I'd say it's far more likely that the 2-hour wait was simply an aberration.
328  Bitcoin / Press / Re: [2019-09-29] A Dangerous Bug in Bitcoin’s Lightning Network Has Been Fixed on: October 01, 2019, 05:50:08 AM
Well, could it be that they delayed telling the public until they fixed the bug.  Wink  How helpful would it have been to tell everyone and expose them to the exploit and only then start working on the solution.  Roll Eyes

Yep, it seems to have been patched relatively quickly, and they held out the public announcement to give people time to upgrade to newer versions.

He didn't say that nothing has happened. In fact, there have been reports of losses that I read about on Twitter. It's probably so deeply buried that crypto news outlets are too stupid to find them.

There doesn't seem to be verified losses. There are a lot of people who are rooting for Bitcoin to fail, and I wouldn't put it past them to lie about losing money.

I already know their headlines.... LN is not secure and therefore Bitcoin isn't secure either. I'm sure they will exaggerate by a factor ten just to make people click on their articles and generate a few pennies.

Suprisingly, that doesn't seem to be the case. Headlines in Google only talk about the vulnerability itself. Bugs are expected out of any beta software, so detractors (same people who wouldn't want to touch it in the first place lol) are really the only ones making a big deal out of this.
329  Bitcoin / Bitcoin Discussion / Re: Bitcoin wallets on older iphones are insecure on: October 01, 2019, 02:33:10 AM
Actually there are website that offers services to spy on your phone just by using your phone number or email, the culprit could just pay some subscription to those websites and he can now access all your logs and data on your mobile phones.

Would you mind shedding some light on this service? I've never heard of such a thing, and I imagine it would be a big deal if it actually worked as you described.

There is a higher chance for a smart phone to be accessed by somebody compared to a personal computer.

While this is true, it should also be noted that phones could actually be protected against thieves by a strong PIN, and that even biometric security measures aren't trivial to crack (except most Androids' facial recognition, don't use that lol). If you're not being personally targeted (which is incredibly unlikely for us regular folk), keeping a wallet in your phone shouldn't be too much of a security issue. That being said, you shouldn't be keeping large amounts of coins outside cold wallets anyway, regardless of whether it's in your phone or PC.
330  Bitcoin / Bitcoin Discussion / Re: Bitcoin wallets on older iphones are insecure on: September 30, 2019, 08:13:43 AM
-snip-

You can't actually break iOS' facial recognition with just photos because it uses 3d recognition. It has been broken with masks, but it's not exactly straightforward.

This is typical Apple support. When a product is only but a few years old, they declare it obsolete and don't bother with updates. They do this with the OSX computers, and of course tablets and smartphones. Kinda like Microsoft, but on a much shorter timespan.

I can tell you right now that Apple doesn't like this exploit at all. It's a jailbreak exploit, something some iOS users actively look for to have more freedom with their devices. It's also worth noting that it hasn't been exploited as of now, and it would be very difficult in practice to use it to steal crypto from someone else -- they would still need to unlock the phone, for one.
331  Economy / Speculation / Re: Will US drop interest rate affect Crypto market in future? on: September 30, 2019, 06:20:28 AM
Hi all, I'm new to Crypto market. Would like to ask will US drop interest rate affect Crypto market in future ?  Because I heard some people said that US drop interest rate = create biggest bubble and might explode next year (financial crisis). If this financial crisis happen, will it affect Crypto market ? If yes, will Crypto market rise or drop ... ?

I would just like to point out that the cut in interest rate is, in part, to reduce the risks of recession thanks to trade crises. Just because it was done in the 2008 financial crisis doesn't mean they're expecting one this time around -- the US economy is actually having a solid performance by most indicators. I don't know where you heard what you did, but people have been predicting the start of the next financial crisis since the last one ended, and some of them have the tendency to exaggerate.

As for crypto on financial crises, the answer is that no one knows for sure, because it hasn't been tested yet. It could easily go both ways, but I personally lean on believing it won't do too well, because people would normally be averse to making any risks during that period.
332  Economy / Economics / Re: Rate cuts money printing inflation on: September 30, 2019, 01:54:19 AM
If so do you think the gold and btc Will be hedge?

Gold is often perceived as a great hedge against inflation, but there's actually data suggesting that that's only true when inflation is in significant levels. [1][2]

Bitcoin shares a few properties with gold so it may act the same way, but being relatively young, we don't really know yet. I don't think we've even seen price growths that could be attributed to inflation -- that might be because like gold, Bitcoin does not react to "normal" levels.

I do feel that, but the problem is i cant buy groceries food and daily needs with Bitcoin first i have to Exchange my btc to Fiat, so the Bitcoin and gold is Not really Solution for that problem!!  

If you're not anticipating Venezuela levels of inflation, it should be safe to keep a portion of your wealth in fiat. You don't have to go all-in on gold and Bitcoin, as they're more for long-term protection anyway.
333  Bitcoin / Bitcoin Discussion / Re: Why would someone use an exchange to shift $1.2 Billion worth of bitcoins? on: September 27, 2019, 02:29:13 AM
The OP clarified their post, saying the $1.2B transaction was within a one-hour period, not a single transaction:

This was within a one hour period, rather than a single transaction. Hope that helps

As for the source of the screenshot, it's their website:

https://bytetree.com/bitcoin

They claim that the coins were transferred from several wallets and sold to exchanges. There's obviously no way to verify this, but it just seems like people are seeing reasons for the price drop everywhere that it almost seems orchestrated.
334  Bitcoin / Bitcoin Discussion / Re: New bitcoin mining algorithm on: September 26, 2019, 08:18:11 AM
If it gets easy to mine bitcoins on a PC,bitcoin will lose it's most valuable feature-it's scarcity.

What people use to mine won't actually matter because of difficulty adjustments.

ASICs mean a more centralized world of BTC where a few manufacturers and a few pools control all the income.  What is so great about that?  Satoshi designed it so anyone could mine and anyone could earn BTC.

I have never understood this reasoning. People with more resources will be able to do whatever they're doing right now no matter what miners are in use. Miners running ASIC farms would just run PC/GPU farms instead. You could also just as easily buy an ASIC miner like you would have a mining PC, so it's not like there's an insurmountable barrier to mining.

It's also worth noting that it would be theoretically cheaper to attack Bitcoin if non-specialized hardware were viable. ASICs turn into bricks after being used in a successful attack (assuming Bitcoin dies), whereas PCs/GPUs would retain their value. Either way, it's best to simply leave things alone, especially because there are no problems to address in the first place.
335  Bitcoin / Bitcoin Discussion / Re: Selling the Bakkt news? on: September 26, 2019, 06:32:17 AM
Do you think they’re selling the news in order to accumulate more Bitcoin? Or Bakkt’s recent news doesn’t really impact at all?

I think they probably sold the news, but for profit and not much else. Bakkt fell flat amidst all the high expectations, so it's likely that traders foresaw this and sold. I don't really believe there are larger forces at play here.

There is no certain thing about what really affected Bitcoin to go down. The fall in the price still surprisingly continues. Also, this may be a sign to a preparation for a big rise. I think the fall will end at around 9000 dollars.

I agree. Because, after all, this is just an American (New York Exchange) thing. And i strongly believe the rest of the world (especially Asia) has more weight.

Everyone reads the same news though, so it's not like Bakkt's speculative effect would be confined to the North American market. I'm sure traders all over the world made some moves relative to this.
336  Economy / Economics / Re: The Latest Crypto Price Dip Is Fueled By Fake News Relating to Quantum Computers on: September 26, 2019, 02:47:16 AM
#1  Quantum keys merely increase the bitsize. It means you upgrade from SHA256 to SHA512 or a larger bitwise number. There's no guarantee that this would be effective against a true quantum computer, if one is ever created.

#2  Clock speed, optimization and a smaller silicon lithographic etching process in nanometers could be cited to claim protection against quantum brute forcing. But would any of those marketing claims withstand the reality of it? Its not something anyone is making an effort to place a guarantee on.

Our disagreement only really hinges on the fact that you believe that we have no idea what quantum computers can do because they don't exist (or practical ones at least) yet, whereas I believe that current projections of their capabilities would be close to what they can actually do. If we have to insist on guarantees against something that doesn't exist yet (and thus couldn't be tested), then there's literally nothing we can do to prepare at the moment. If that's your line of thinking, then I suppose your belief on its effect on prices is justified.

#3  There have been many many BTC price movements traders couldn't explain that were easily explainable by stories published in the news at the time.

I'll give you one example:

https://bitcointalk.org/index.php?topic=5142884.msg51040602#msg51040602

That news story could explain the recent spike in BTC price which traders also could not explain @ the time.

True, but it could also be explained by Bakkt being announced one day prior to that post.

The current drop also coincided with Bakkt starting slow, so I believe it's more likely that traders are more interested in watching Bakkt than Google's paper. I could be wrong, of course. Pointing to what caused price movements is difficult even in hindsight, but I think it's reasonable at this point to assume that the hype (and that hype being shot down) behind Bakkt can move the market.
337  Economy / Economics / Re: The Latest Crypto Price Dip Is Fueled By Fake News Relating to Quantum Computers on: September 25, 2019, 08:14:33 AM
#1 A new public key wouldn't defend against quantum brute forcing.

I was referring to quantum proof public keys, which are already ready today but have a few issues:

Public-key crypto that is secure against QC does exist, however. Currently, Bitcoin experts tend to favor a cryptosystem based on Lamport signatures.

#2 Quantum computers attempt to achieve higher performance through increasing the data density of bits. Rather than exclusively utilizing binary digits with 0's and 1's as today's supercomputers do, quantum computers expand the number of base values utilized in the computational aspect of things. That's where their theoretical performance boost comes from.

A normal supercomputer could be characterized as a person who only has 2 fingers (bits) to count on. While a quantum supercomputer could theoretically have hundreds, thousands or more fingers (bits) which gives them a larger computational density.

I think quantum computers are equivalent to someone attempting to build a moped engine that can produce 200,000 horsepower while consuming the same amount of gasoline as a normal motor. They're supposed to be powered by breakthroughs in quantum physics which will likely never manifest.

Again, there's a study saying that current ASICs are faster than theoretical quantum computers when it comes to mining because they're specialized:

We find that the proof-of-work used by Bitcoin is relatively resistant to substantial speedup by quantum computers in the next 10 years, mainly because specialized ASIC miners are extremely fast compared to the estimated clock speed of near-term quantum computers

So if this is accurate, Bitcoin doesn't really have to worry too much about getting 51%'d by quantum computers, or at least  not in the near future.

The entire premise of encryption is not that its unbreakable. But rather that it would take *too long* to break encryption for it to be feasible.

When tech corps like google release fake news claiming their "quantum computer" can solve problems in "200 seconds" that would take a normal supercomputer "10,000" years to solve.

That is a direct reference to existing encryption standards. That is a definite connection imo.

Yeah, all I was saying is that I don't think a lot mainstream readers would be able to draw that connection, which is why I believe that it's unlikely for the price slide to be attributable to the news piece.
338  Bitcoin / Electrum / Re: How safe is Electrum wallet? on: September 25, 2019, 07:12:59 AM
You can make one that doesn't directly connect to the internet.
Keep your keys offline by setting-up a standard wallet in a cold-storage device that holds the keys for signing and an online watch-only wallet using the offline's "master public key" for receiving/making transactions.

As an addendum, here's a guide on how to set that up:

https://bitcointalk.org/index.php?topic=4573616.0

If you don't have an extra computer that you can use for this, you can very easily use any extra flash drives you have lying around -- you only have to install a persistent copy of Linux that you can safely boot on any computer, or even persistent Tails. Just make sure you verify your initial download using the guide in electrum.org, and that you keep your seed in a safe place.
339  Economy / Economics / Re: The Latest Crypto Price Dip Is Fueled By Fake News Relating to Quantum Computers on: September 25, 2019, 05:51:25 AM
If bitcoin's encryption is broken, it could take years before its fixed. If it is ever fixed. Encryption being broken in crypto currencies is a doomsday scenario. The only true fix to true quantum computers could be quantum level miners utilizing quantum level encryption.

Not really. A new public key algorithm could be introduced with a simple soft fork, and current ASICs are faster than projected quantum computer clock speeds. The problem is that old and some lost coins can't be protected, since they can't be moved to post-fork addresses.

I agree with notions that quantum computers will never become a reality. There is only so much functionality that can be built into silicon or chips made with other materials. Whether limited by voltage, clock frequency or data density. I think there are hard physical and theoretical limits which could prevent quantum computers from reaching the standards their marketing brochures claim are possible.

I believe they're inevitable, but I don't think they'll be available for commercial use anytime soon. Entities who would have access to ones strong enough to threaten Bitcoin probably won't be interested in it in the first place.

As for the actual topic, I also believe the price movement had something to do with the brief hashrate crash. I'm not sure mainstream readers would actually know that there could be a connection between quantum computers and Bitcoin unless it's explicitly mentioned in the article (and articles I've seen don't).
340  Bitcoin / Bitcoin Discussion / Re: Privacy at risk using mobile phones. Not only Bitcoin-related. on: September 17, 2019, 07:05:24 AM
Don't keep coins on exchanges is acceptable but don't keep coins on phone? i don't see any reason why because i think its safe on my own side, i have been keeping my coins on phone since 2016 and i have no issue till date, secondly my phone has inbuilt fingerprint and face recognition for anyone to access

He probably only said that because it's easier to lose coins in your phone than in your PC, but if you know what you're doing, phones should be perfectly viable for storage. This attack, for one, is practically limited to tracking victims, so there shouldn't be any risk of crypto loss. Just make sure you don't keep large amounts anywhere that's not cold storage.
