[Bitcoin] trades like a call option on a new [monetary] system

hmmmmm

Well, sounds familiar...
Of course...I said exactly (almost) the same on Aug 2 (5 days earlier) on this very forum, lol:
https://bitcointalk.org/index.php?topic=178336.msg52033878#msg52033878

Bitcoin itself trades more like an option (on a new financial system, I guess).

But, of course, on the internet ideas disseminate quickly and no one ever quotes anyone. Oh, well.

Why is there a dollar liquidity crisis even with the govt printing tons of it?  Probably because at the end of an unsustainable growth cycle, there's no reason for any company to be expanding or building new projects, so all these companies like Apple, Google, and everyone else are sitting on hundreds of billions of dollars just doing nothing.  The economic system is a complete failure and caused most of the money to centralize in a handful of corporations. Negative interest rates do absolutely nothing to fix that because there's still no reason to expand and NIRP just creates an even worse economy.

Just because they have these billions doesn't actually make them smart money, though.  In a world where it's blatantly obvious the only way for the system to continue is massive devaluation of debt through huge inflation, anyone sitting on enormous amounts of fiat is a complete idiot.  These guys are the dumbest money in the room.  Instead of holding hundreds of billions of dollars in cash, they should be holding billions of dollars in gold and silver.  And that's probably where these billions will be heading once govts are forced to massively devalue the fiat.

Good morning WO! It seems that the support at 11400 has increased dramatically in Bitstamp. May be another leg up will follow shortly that will lead to a new AYH. Holding my breath

Central banks around the world are slashing interest rates.

Soon they'll start printing egregious amounts of money.

Bitcoin halving approaching quickly.

Buckle up.

This may get insane.

Details of the OLED Vulnerability and its Mitigation

This article describes an information leak discovered in the OLED display used by hardware wallets, including Trezor One. We want to explain how this side-channel attack works and what measurements we took to mitigate the threat. This attack affects only the Trezor One; Trezor Model T is immune to this attack thanks to its entirely different display.

Very smart!

Ledger too.

Like many hardware wallets, the Ledger Nano S and Ledger Nano X include an OLED screen to display sensitive information. In the case of Ledger’s products, the following information is displayed on the screen:

• The confidential recovery phrase during the setup,
  
• The PIN code entered to unlock the device.

As this information is confidential, we always recommend our users to operate their devices in a secure environment. In an unsafe place, someone could eavesdrop and gain access to critical information, and thus to your crypto assets.

This is like telling people to put toilet paper between their hand and arse before wiping off.
But many still don't even cover the keypad of an ATM machine when putting in their pin code

Good morning at $11.827 (another reject before bounce?)

Thanks.

I really enjoy reading about such vulnerabilities, not only in order to take the necessary measures to protect myself (f/w updates, etc.), but also to admire the efforts of the hackers (well, the researcher in this case), for their ingenuity and cleverness. I'm an electronics engineer and I'm absolutely in love with my work. I can imagine the excitement that Christian Reitter felt when he saw those patterns on the oscilloscope's screen.

I think TREZOR's countermeasures are better than Ledger's. TREZOR's solution totally equalizes power consumption between different seed words, but sacrifices looks, while Ledger's maintains good looks, but sacrifices a little bit on security (screen content can theoretically still be inferred by power consumption patterns, but the process is now much more difficult).

tl;dr: Treat your TEZORs/Ledgers as physical wallets (like the one in your pocket carrying your fiat). Don't assume you are fully secure by using them. You can't begin to imagine what a good hacker can do once your device is in his/her hands...

Edit: Check out the following related story. Long, but well worth the read. Hats off to the hacker!

And also, what I admire in Trezor is they do the action fast, even the vulnerability is not quite risky but they manage to make another version of the firmware update so the security will upgrade, while the Ledger (on this vulnerability, they said, Q4 2019 will be added the mitigates on this vulnerability, since it is too long, maybe they can create much better solution for that vulnerability, we don't know... )
Btw, here's the thread about the recent OLED display vulnerability on some hardware wallets.

Wow we are now looking at a new ALL YEAR HIGH anytime soon nice.

Bull 1
Bear 0

Though I think the bear has more overall points if we base this on the ATH.

Is er een Nederlands Bitcoinfeestje waar ik niks vanaf weet Or do you need a minimum amount of BTC to join

[somac.]

more than 1 hour to get a block, I hate when this happens when I need to transfer some corn around within a reasonable time frame.

Good afternoon WO!

Yeh kya drama macha rakha hai!!!

Wow.
Considering hashrate is at historical maximun this is quite weird.

Bitcoin Network Hash Rate Hits 80 Quintillion for the First Time

Data from monitoring resource Bitinfocharts confirmed Bitcoin’s hash rate exceeded 80 quintillion SHA256 hashes per second Aug. 8, the first time such a level has been reached.

EDIT: Sorry, shall we read your quote as:

more than 1 hour to get IN a block, I hate when this happens when I need to transfer some corn around within a reasonable time frame.

This is quite different and has probably to do with a wrong fee estimation.

Yes because despite high price fees haven't never been so low:

Despite Criticisms It Can't, Bitcoin Is Scaling

[...] transaction fees are the lowest they’ve ever been when Bitcoin is trading above $10,000. On August 4th, the median Bitcoin transaction fee was $0.15 per transaction. Typically the fees associated with Bitcoin transactions follow prices. With higher prices, higher fees tend to follow.

This is a peculiar situation. Never before in Bitcoin history have we seen fees as low as $0.15 when prices were above $10,000. The next closest day of transaction fees was February 21, 2018, when Bitcoin transaction fees were $0.19 during one of the final days above $10,000 in the 2017/2018 bubble. Most days with Bitcoin prices above $10,000 had transaction fees well above $1 per transaction — sometimes as high as $30.
