A 30-35% crash, like the 1987 crash, could easily be enough.
We've already seen a 30% crash in the markets. A month ago, NASDAQ was at 9,800. Today it's at 6,900. Dow Jones from 29,300 to 20,200. Most foreign markets - FTSE, CAC, DAX, etc - are showing similar 30% drops. This is even with the Fed announcing another $700 billion of QE and cutting interest rates twice to zero percent. And even now, we've haven't even begun a proper quarantine, and the suggestions coming from the WHO and top medical/scientific advisors is that this could last for months. Governments around the world are already starting to bail out airlines and other travel companies after only a week or so. I hope you're right, mostly for the sake of all the people who are going to be out of jobs and struggling to get by, but I fear this is just getting started.

The WHO have now said essentially the same as what we were discussing above - although the only evidence is from sporadic case reports, it would be wise to avoid NSAIDs for the time being.

I think its premature to assume china has its issue contained.
It helped that the country is a totalitarian one
These are both important points, and these two reasons are why we shouldn't be comparing western countries to China, or looking at China for what to expect in the coming weeks or months.

China actively suppressed information about the disease and about the severity of the disease for many weeks, and actively prosecuted doctors who spoke out about it online. It's not exactly a giant leap to expect that they are also suppressing information about their true number of cases and deaths.

China implemented a very severe isolation policy, which western countries haven't even come close to. Even if you compare to Italy, which currently has the most severe and restrictive quarantine policy in the west, it's still nowhere near as restrictive or as strict as that of China. Meanwhile, the US is still throwing St Patrick Day's parties.

I will store those words physically using the BIP39 Split Mnemonic in 2 separate places.
This is risky without also creating additional back ups. Splitting your seed phrase in to two means that if either piece is lost/stolen/destroyed/degraded/unreadable/whatever, then your coins are lost and the other half is useless on its own. I would always advocate for multiple back ups - if storing your seed phrase whole then that means two separate back ups. If splitting in to two then that means four separate back ups - two of each half.

I wanted to encrypt the 24 words string using AES 256 bits and then print the encrypted string, but I haven't found a good tool to do this.
If you do this, you will need to also back up your encryption key, again on paper and in a separate location to your encrypted seed phrase. Although rather than encrypt the seed, why not leave the seed as plain text and use an additional BIP39 passphrase instead? It has the same desired outcome, in that an attacker must find both your seed phrase and your passphrase to access your funds, with the added advantages that it takes longer to brute force a passphrase as for each attempt an attacker also has to derive at least one address and perform a look-up to see if that address has a transaction history, as well as allowing for plausible deniability.

How is it a marketing trick? Can you please explain.
Because anyone who understands how bitcoin works, and understands what transaction batching is, will be thoroughly underwhelmed by this. Individual users like myself have been using transaction batching for literally years. If we can do it, then there is absolutely zero reason that arguably the largest and most valuable bitcoin related company in the world couldn't also do it years ago. In reality, the fact that it took them this long to finally implement it should really be a source of embarrassment for them, not something to announce to the world as if you are making some massive progressive strides forward.

They have announced it with great fanfare, and a bunch of newbies who don't understand any better will think "Oooohhh, they are saving me some fees, isn't that amazing! How great are Coinbase!", whilst anyone who understands what is going on will just roll their eyes.
10866  Bitcoin / Bitcoin Discussion / Re: Why Does Bitcoin Have Value? on: March 17, 2020, 08:01:57 PM
Without its Fiat value Bitcoin won't be accepted by any vendors online or offline.
Says who? There is a merchant I buy from fairly regularly whom I (and several others) pay in bitcoin, who has told (and shown) me that he then uses that bitcoin to pay part of the salary of some of this staff members, and also to pay one of his suppliers. His employees which are paid partly in bitcoin are paid with a fixed amount of bitcoin, regardless of its fiat price. They earned relatively more in terms of fiat last June/July when the price was $13k, and they will earn relatively less currently in terms of fiat, but they always earned the same amount of bitcoin.

Bitcoin can function just fine without fiat. I earn a fixed amount of bitcoin from my signature and avatar, regardless of fiat price. I buy things from this merchant who pays his employees in a fixed amount of bitcoin, regardless of fiat price. There is no inherent need to convert to, or even think about, fiat when using bitcoin, unless you want to.

I will make a single post in this thread only. As I stated in the OP of my thread, it is for serious discussion only, with evidenced based guidelines and treatments. You have countless other threads you can derail with your Big Pharma conspiracy theories.

I've not mentioned vaccines once in that thread, so your entire argument on that point is a meaningless strawman.

As to your "take all your meds" argument, two medications were raised, one of which I said I wouldn't take, so again, your argument there is a strawman.

franky1, I simply deleted your post since it made no sense without the context of tvbcof's spam.

There are cases where it would be wise to keep an eye on the research involving the interaction of commonly perscrived medications (esp things like ACE inhibitors) and switch to a different method of dealing with existing problems if a particular medication is proven or strongly suspected of being detrimental to covid-19 specifically.
There is absolutely no evidence that ACE inhibitors or ARBs result in either more infections or more serious infections with SARS-CoV-2, but there is some evidence that they exert a protective effect against ARDS (which would mean stopping them would result in more deaths). There is no "proven or strongly suspected" detrimental effect as you suggest. A vague hypothesis is neither proven nor "research". If you have some evidence-based studies to substantiate these claims, I'd be more than happy for you to post them in my thread, but you don't because none exists. If you continue to post conspiracy theories and non-evidence based nonsense, I will continue to delete your comments.

If I come back with same BIP39 Mnemonic, the addresses will exactly display in the same order??
Yes. Provided you use the same derivation path as you did before (the derivation path is the m/44'/... part), then you will generate the same addresses in the same order.

So I guess, every time I receive a new payment I take the next address in the display order after the last one I used and this way I will be able to keep track of all the addresses on which I have BTC.
Yes.

Is this the right way to perform if I just want to rely on a offline javascript Mnemonic Code Converter (no wallet app or web-based wallet)?
This is one way you could do it. Another way would be to export your seed's master public key, and create a watch only wallet using it in a client such as Electrum. It would show all your addresses, all their balances, a total balance, but can't be used to spend coins and can't be hacked, as it is built only using the public key and not the private key.

Fiat currencies seem to be holding up just fine.
Maybe during the panic phase. People are pulling their money out of all these other falling markets, and so fiat gets an artificial boost. Most experts are now suggesting several months of lockdown, quarantines, school, college, university closures, bar, restaurant, club closures, etc. Retail industry collapse, service industry collapse, travel and tourism industries collapse. We are already seeing hundreds of thousands of jobs being lost and the shutdowns have barely even begun. Economies will start to tank and fiat currencies along with them.

my gut tells me the corona virus panic will subside soon.
The panic will subside soon as the novelty wears off, and the panic buying will subside as you can only hoard so much and a lot of people will soon be struggling for income. However, the virus and the shutdowns will not. This is expected to drag on for months.

Would you elect a president who received 0 votes or another one who received a million votes?
I would vote for whichever one most closely represented my views, regardless of what other people think.

Why is it all about the ability to re-spend something which makes something valuable?
If the votes are worth nothing, then how do they help to narrow the gap between rich and poor in any way? If there is no difference between earning zero votes or 10 million votes, then what do they actually achieve?

Yes, they can withhold their votes, it's their choice.
Ok, so no penalties for the selfish.

Why not? Throw in the buzz words.
As I suspected. You haven't actually thought this through, and are just using blockchain as a selling point, much like the majority of scam ICOs and tokens.
10871  Economy / Economics / Re: Interest rates to 0%, $700 billion in QE, and reserve requirements to 0% on: March 17, 2020, 10:49:29 AM
So QE is not a concerning news - just the amount is higher this time!
Sure, QE happens quite frequently (far more frequently than it should), but they haven't even come close to paying off all the QE from 12 years ago. Their balance sheet is still running at its highest ever levels, and they are going to pump it by another $700 billion. QE only works if you can reverse it and take the money back out the system during times of non-crisis, which they haven't done. Performing QE upon QE upon QE can only last so long before the whole system collapses.

This limit is lifted means, banks can now lend 100% of their deposits and if a big percentage of their loan becomes NPA, you and I will be royally fucked!
It's actually worse than this, as I explained above. Although yes, banks can now lend out 100% of their deposits, it also removes any limit on how much credit they can extend to their customers. They can lend out 100% of their deposits and they can lend out any amount more that they like on top of that.
10872  Bitcoin / Hardware wallets / Re: OpenDime or Hardware Wallet? on: March 16, 2020, 08:49:36 PM
It's my understanding that in order to hack the Trezor to obtain the seed-phrase the hacker needs to have the wallet in hand (i.e. physical attack,) and he must know the PIN.  Even the strongest PINs are vulnerable to brute force, being composed of numbers only.  Like Ledger models, both Trezor wallets have a security feature that wipes the device if the wrong PIN is entered three times.
An attacker must have physical access to the wallet, yes. However, in the attack as detailed by the Ledger Donjon team here (https://donjon.ledger.com/Unfixable-Key-Extraction-Attack-on-Trezor/), the PIN is bruteforced at a hardware level, meaning the security features of a prolonged delay between attempts or locking the device if too many wrong attempts are made are bypassed. The PIN is brute forcible in a matter of minutes.

So, one can reason that if the PIN on a Trezor is trivial to brute-force, then why would the PIN on a Ledger be any more secure?
There has been no similar attack demonstrated on a Ledger device in which the 3-strikes-and-you're-out PIN protection system has been able to be bypassed.

I'm assuming that anyone who has set up a Bip39 pass phrase on their Ledger has also attached it to a secondary PIN (which should also be "trivial" to brute force.)
I've never used the "attach to secondary PIN" feature, but it would still be secure unless a similar attack was demonstrated as above.

I am seeing reports that people who take ACE inhibitors and anti-inflammatory drugs may be more susceptible. Do you have any information on this?
Nothing beyond anecdotes, a lot of which are coming from social media and therefore notoriously unreliable. For example this message which has been widely circulated online regarding "4 young people in a serious condition" who were taking NSAIDs, which was called out as being fake by the society who supposedly released it - https://www.thejournal.ie/ibuprofen-cuh-coronavirus-whatsapp-5047311-Mar2020/

The underlying mechanism being proposed is that NSAIDs and ACE inhibitors cause up-regulation of the ACE2 receptor, and it is this receptor which allows SARS-CoV-2 gain entry to human cells. However, there is also evidence that ACE2 exhibits a protective effect in ARDS (acute respiratory distress syndrome), which is what patients with COVID-19 are dying from. The position statement from the European Society of Cardiology is to continue taking anti-hypertensive therapy as prescribed by your doctor, which I would agree with. However, unless you have a strong reason to be taking a NSAID (like rheumatoid arthritis, for example), I would probably be avoiding them and sticking to acetaminophen/paracetamol.

Having said all that, it makes little difference to my individual practice in intensive care. I couldn't tell you the last time I used a NSAID in intensive care, and the vast majority of our patients with severe infections, sepsis, multi-organ failure, etc. are hypotensive, rather than hypertensive, and generally have most, if not all, of their anti-hypertensive medication stopped during their time with us.
10874  Bitcoin / Bitcoin Discussion / Re: Tyler Winklevoss: BTC is not a hedge to pandemics on: March 16, 2020, 03:52:04 PM
As others have said, bitcoin will recover, and when it does, it won't have taken negative interest rates and a couple of trillion dollars printed out of thin air in the name of "quantitative easing" to get there.

What really bothers me is that this pandemic will push the world into a new recession
Absolutely, and it is going to be horrific. Before 2008, the Fed's balance sheet was only around $800 billion, and interest rates were over 5%, which provided a lot of leeway for interest rates to be cut down to 0-0.5% and for the Fed to pump out almost $4 trillion in QE. The Fed had only just started to manage to reduce their balance sheet from 2008, and got it from $4.5 billion down to around $3.8 billion, before the overnight repo nonsense from the end of last year pushed it back up again. Now, in the space of a couple of weeks, they've cut interest rates twice back down to 0%, and they've committed to another $700 billion in QE, which will push their balance sheet back to an all time high of almost $5 trillion. The national debt and deficit are both rapidly increasing. The Fed have nowhere left to go other than negative interest rates and printing money even faster. The coming recession is going to be horrific, and USD is rapidly becoming worthless.

I was thinking institutions can now borrow from the reserved bank and paying 0% interest rate which I expect the same institutions will help keep their lending rates to consumers at its lowest
Yes. Commercial banks can now borrow from central banks at no interest. Consumers usually see the reduced interest rate reflected in their savings almost immediately, with banks reducing the amount of interest they pay their customers almost immediately, but it takes several months before the banks drop their loan repayment rates, mortgage rates, etc. to reflect this. Anything to squeeze more money from their customers.

From what you wrote, it seems they are now allowed to lend out money to consumers without regard to their savings in reserve. I will want you to explain this more with a simplified logic.
So when a bank gives out a loan, new money is created out of thin air. What a bank does is credit your account with $1,000 (for example), whilst also creating a debit you owe them for the same value of $1,000. The bottom line of the bank's balance sheet doesn't change. $1,000 out, $1,000 owed, bottom line remains 0, but $1,000 of new money has just entered circulation. This is where the majority of new money comes from - banks creating it out of nothing when people take out loans. This is how modern banking works, and has done for decades.

Now, banks also practice a system known as "fractional reserve". As the name suggests, banks must have a fraction of the value of their liabilities in reserve at any one time. This has been set at 10% since 1992, when it was lowered from 12%. This means that if a bank has $1 billion in reserves (for example), the most they could loan out would be $10 billion. However, from March 26th, the reserve requirement is 0%. This means banks can loan out as much money as they like. Bearing in mind what we've said above, in that every time a bank gives out a loan like this new money is created from nothing, this essentially is giving the banks free rein to print money.

Fiat is collapsing.

https://www.cnbc.com/2020/03/15/federal-reserve-cuts-rates-to-zero-and-launches-massive-700-billion-quantitative-easing-program.html

The first two parts of the topic subject are entirely expected. The Fed have cut interest rates for the second time in a month, now down to 0%, and they've launched another $700 billion in quantitative easing, despite the Fed's balance sheet still being massively over inflated from all the previously rounds of QE. What was perhaps not as expected was how soon they have done this. This pandemic is only just getting started, there is a long way things can fall yet, and the Fed are now rapidly running out of options.

Far more concerning, however, is the news that they have dropped banks' reserve requirements from 10% to 0%.

The Board has reduced reserve requirement ratios to zero percent effective on March 26, the beginning of the next reserve maintenance period. This action eliminates reserve requirements for thousands of depository institutions and will help to support lending to households and businesses.

When banks lend money to customers, they create new money out of nothing by creating matching credits and debits on their balance sheet. The reserve requirement limits how much they can do this, because they have to have a certain portion of this money, currently 10%, in their reserves. This new action removes that requirement altogether, giving banks unlimited rein to create as much new money as they like, at no cost to themselves.

Hyperinflation is coming. Fiat is collapsing.
10878  Economy / Economics / Re: Can we agree BTC is not a store of value? on: March 16, 2020, 12:05:59 PM
Nothing is a store of value at the moment. Global markets are down, gold, silver, copper and platinum are down, oil and gasoline are down, corn, wheat, cocoa, and coffee are down, futures are down, FTSE, CAC, DAX, IBEX, Hang Seng, Nikkei, Shanghai, RTS, ASX are all down. The only reason NASDAQ/Dow Jones/S&P have stabilized a bit today is because the government have cut interest rates yet again, now down to 0%, and announced yet another round of quantitative easing (although did the last round ever actually finish with all those "overnight" repos?) to the tune of $700 billion, with much more likely to come.

Everything is decimated at the moment, but the Fed have moved too early and are now out of ammo. They have nowhere to go from here other than printing even more money even faster than they already are, or negative interest rates, which will be a disaster for them. When fiat is rapidly devaluing because the Fed are injecting trillions in to the system, and you have to start paying your banks for the privilege of them holding your money, where do you think people might turn? This is only just beginning.

We have, but it's futile. The "COVID" center is already at bursting point, and it is now becoming so widespread that people attending the other hospitals for unrelated issues are now testing positive for COVID as well. With cases doubling every 3 days pretty much everywhere, by the end of this week every hospital will be a "COVID" hospital.

That's not the issue here. If you read above, it's because the amount he requested is more than the amount he received. The request will remain unfilled until he performs another transaction for the requested amount.

But 3 confirmation is enough where you can spend your Coins out from Electrum.
You can spend coins from Electrum after fewer than 3 confirmations. You can even spend unconfirmed transactions from Electrum, which will automatically confirm the first transaction when the second transaction is confirmed. This is the basis for child-pays-for-parent transactions.
