One of the world's biggest banks just admitted bitcoin could destroy existing finance firms
http://www.businessinsider.com/bnp-paribas-bitcoin-blockchain-securities-firms-redundant-2015-7French bank BNP Paribas says the technology underpinning bitcoin has the potential to make existing companies "redundant," a huge admission from one of the world's biggest banks.
Analyst Johann Palychata writes in the company's magazine Quintessence that bitcoin's blockchain, the software that allows the digital currency to function, "should be considered as an invention like the steam or combustion engine," that has the potential to transform the world of finance and beyond...
If investors can trade shares directly with each other in a system that has a layer of trust built into it then middle men — stock brokers — aren't needed anymore.

Here is how secure it is.
Imagine you built a perfect computer; Forget about GHash and Megahertz.
You built a computer which used the absolute minimum amount of energy theoretically possible to record a change in a single bit. [ 1 to 0 or 0 to 1 ].
Now imagine you used most of the natural resources in our star system to construct a Dyson sphere and covered the entire surface of this sphere with a single star system sized super computer.
Now imagine you could keep this supercomputer cooled at roughly absolute zero and could do so without expending any additional energy.
If you had that and captured (with no inefficiency or loss) the entire energy output of our star
(not just in a day or week, but continually until it burned out) you couldn't COUNT to 2^256 before you ran out of energy.
Keep in mind this is simply counting.
Just counting, not hashing, not comparing, not performing lookups just counting 1....2....3....2^256-1.
These numbers have nothing to do with the technology of the devices; they are the maximums thermodynamics will allow.
And they strongly imply that brute-force attacks against 256-bit keys will be infeasible until computers are built from something other than matter and occupy something other than space.
parts about Cryptocurrencies. Bitcoin is knowable over time and all assets are accounted for in the Blockchain (essentially a decentralized electronic ledger).
For example, let's say the NSA wanted to know what you are doing with your Bitcoin. Indeed, they could figure it out by attempting decryption (however, it may take them a generation) ... However, the resources it would take to decrypt one person would be crippling.
there is a good discussion here http://security.stackexchange.com/questions/25375/why-not-use-larger-cipher-keys/25392#25392
The economic crisis started in 2007. Greece's internal devaluation/deflation started after the Greeks started implementing austerity measures demanded by the Troika.

So you are looking at US inflation numbers and saying Greece didn't have any deflation.
Seriously? You actually posted something that pathetic?
Because you handing someone money at the same time they hand you what you are purchasing is 100% untrustworthy.
There are many ways to make a transaction secure. Bitcoin uses one. The reputation of the seller is another. The system of laws against fraud is another. The insurance supplied by a credit card is another. A commodity exchange and its rules are another.
Bitcoin is not the only way, as much as you love it.
You do realize that Bitcoin is based on standard encryption algorithms, right? Meaning a metric fuckton of those systems existed prior to Bitcoin.
Also, bitcoin wasn't even the first attempt at a digital currency. It's rev 2. Because rev 1 was broken.
I realize you are evangelizing here, but you do not fundamentally understand the technology you are talking about. Instead, you're quoting tropes other people have said while stripping off important qualifiers.
A little like saying "I can treat your respiratory illness, because I read some about the rhinovirus". When they die from bacterial pneumonia, you might realize you didn't have some important information.
Indeed, it is slow now, but as the blocksize being processed is increased, so is the speed. They increase the blocksize as the need requires - and how they have done in the past. This process most definitely will scale into the future and theoretically could reach VISA level transactions around 2032.
One employee of a singular bank allowing an analysis doesn't really seem to rise to the level of "apparently scare a major bank."
However, I realize we're often biased and evangelize about those things we're passionate about, and more often than not perceive mere disagreement as an attack on own sense of worth and identity and you appear to have done numerous times throughout this thread... regardless of who bitcoin needs or doesn't need. 
I suspect it's a black-ops project to build a tool useful for cracking common sorts of encryption, to build a sort of rainbow table.
All those bitcoin miners may be unwittingly working for the NSA or some unknown agency.
Have a Nice Day!
