Researchers Discover Flaws in Digital Currency Monero That Could Reveal Identity of Users (wired.com)
Researchers have discovered flaws in Monero, a digital currency that boasts a high degree of anonymity, that could lead to the identification of users. From a report: Monero is designed to mix up any given Monero "coin" with other payments, so that anyone scouring Monero's blockchain can't link it to any particular identity or previous transaction from the same source. But in a recent paper, a team of researchers from a broad collection of institutions -- including Princeton, Carnegie Mellon, Boston University, MIT, and the University of Illinois at Urbana-Champaign -- point to flaws in that mixing that make it possible to nonetheless extract individual transactions.
That shouldn't just worry anyone trying to stealthily spend Monero today. It also means evidence of earlier not-quite-untraceable payments remain carved into Monero's blockchain for years to come, visible for any snoop that cares to look.

There is a reason there is FDIC insurance in the US...
Teddy Roosevelt did that FIDC thing in a somewhat successful effort to stem the tide of the great depression by printing a LOT of money to bail out the insolvent banks. This was designed to stop the bank runs that where sucking all the cash out of the economy by stuffing it into mattresses for safe keeping.
It was the original "To BIG to fail" bail out, at taxpayers expense and we've not been able to stop doing it for every financial hiccup since.

Franklin, not Teddy. And Roosevelt might well have been more interested in protecting depositors than in protecting banks.

Anyone who's surprised by this isn't suspicious enough of the idea that a currency built on a permanent public ledger of transactions could possibly be anonymous.
If so-called cryptocurrencies are really good innovation, why they attract so many criminals/criminal activity?
Could it really be because, all cryptocurrencies themselves are scams, and that is why they attract all kinds of criminals/criminal activity?
If so-called cryptocurrencies are really currency, why no company/store can use Bitcoin as currency anymore?
Because the price of Bitcoin proved to be extremely unstable to use as a currency?
Would the result be different, if Bitcoin replaced by any other "cryptocurrency"?
Aren't all work the same way?
Or, they are not actually virtual currency but virtual investment?
But, if they are actually investment, why we need/want them?
What would happen to world economy, if people invested in virtual investments, instead of real investments?
Or, all so-called cryptocurrencies are actually just a modified Ponzi Schemes?
(Price of cryptocurrencies would keep increasing in the long term (by their design), so it is equivalent of paying variable interest to all long term investors.)
As more and more people invest in cryptocurrencies, it will become harder and harder to ban their trading everywhere!
All cryptocurrencies need to be banned globally before it is too late!
The price of Dogecoin is extremely stable.
From day one, one Dogecoin has always been equal to one Dogecoin.

Monero has several functions to create anonymity, each one on it's own doesn't do it but combined there is a nice proof that they do. Every 6 months some idiot points out that one of the functions can be beaten. It's so common I'm not even going to bother reading the paper this time.
It wouldn't matter if they WERE the best and brightest. If you study cryptography you learn about famous cryptographers such as Polybius, Trithemius, VigenÃre, Stager, Scherbius, Rivest, and Schneier. These are the best cryptographers the world has ever seen. They all have own thing in common - their creations have all been hacked, broken.
A fundamental law is that it is easier to break something than to make that thing. Physicists call this "maximum entropy" - things naturally tend away from order and structure, things break more easily than they are made. Any cipher, any encryption, which can be made by people can broken by people.
In cryptography, as in crime, one side has an almost insurmountable advantage. The cryptographer can come up with huge, complex systems with many parts. The cryptanalyst needs only find a single flaw, a single shortcoming or shortcut, anywhere in the system. Cryptonanalysists will amost always beat cryptographers for the same reason a determined police force will almost always find their murderer if they try hard enough - the murderer has to do everything perfect to get with it, the police only need to find that one stray hair, with its DNA, or one drop of blood under the carpet, to prove their case.

Which amendment in the Bill of Rights says a company doesn't have the right to refuse to service another company?
It's the one right next to the amendment allowing the government to strong-arm and blackmail financial institutions with threats of endless investigations by government regulators into refusing to allow legal businesses to perform legal commercial transactions with law-abiding citizens for purely political reasons.

> If they have been used correctly, such as the way ssl does PFS, wherein the keys used at the time are only ever used once then forgotten, it becomes impossible to glean any record of past transactions
SSL PFS has in fact been broken. Over 80% of web servers used group 1, most SSL VPNs used group 2, and all of the others used group 3 or 5. We know for sure group 1 was publicly factored, allowing the (backward) decryption of most web SSL. There is evidence that NSA factored group 2, allowing them to decrypt most SSL VPN sessions.
Your very example of what can't be broken was broken, three years ago.
Yes, Franklin.. Sorry for the mistake.
Protecting depositors by bailing out banks... To get money back into circulation by getting it back into banks and not stuffed in mattresses... Sort of the "trickle down theory" if you think about it.
Actually, I think the real benefit was to expand the money supply dramatically and quickly. Even with that, recovery was muted by the dust bowel and what Carter would have called a "general malaise" where the population was focused on possible impending doom and hesitant to take risks. The real recovery didn't start in earnest until the outbreak of WWII and the massive military spending by all sorts of countries buying arms from the USA...
Of course.. The danger of this printing money thing is inflation, and eventually the price will be paid though the devaluation of savings because it buys less and less over time. In 1900 a million dollars was quite the mound of cash and almost nobody ever saw that much in their lifetimes, now days, many people see a million dollars go though their hands every few years.

" In 1900 a million dollars was quite the mound of cash..."
Actually, not so much - yes it was a LOT of money back then, but the US also printed $5,000 bills. So a million could be a neat little stack of 200 bills. Today, however, it's a mound.
