What's with everyone in this thread bashing on D-Wave? If it was really bullshit companies wouldn't be buying D-Wave's units. Quantum computing is simply in it's very early stages, and it's benefits are going to be really limited to niche problems where regular processors do a really bad job.
And there's nothing BS about quantum physics, why would you doubt quantum superposition? That's plain ignorant.
It's because their product is "adiabatic" and does not necessarily work like a true quantum superposition-based computer would. There isn't even necessarily evidence that the universe even really works in such a way as to allow the theoretical conception of what a quantum computer would really be like to exist in the first place.

Just to throw this out there, here's something immediately slimy about this guy that puts off anybody with a good sense of intuition --
On this forum he says something early on that suggests he came here disparaging having tried reddit first, and on reddit he says that he tried here first.
That's very much in the wheelhouse of scammy manipulative con artist pandering techniques.
Also soliciting roughly $25 million in Bitcoin capital without having a clue where to start? Really?

Breaking news!
Some butthurt zilch who produces quotes for some inconsequential internet publication that caters to people with sub-100 IQ's regurgitates the same ignorant talking points as everybody else with zero direct knowledge of the subject.
Thanks for chiming in Byron Wien, and congrats on socially-engineering yourself to become one of the lucky monkeys flipping a coin that run hedge funds.

Localbitcoins is a much better solution than anything that can possibly be accomplished in this thread.

The D-Wave is not really a "quantum computer" in the conventional sense, it uses quantum annealing. The practical problems related to actually implementing computational entanglement are absolutely ridiculous in scope, and at the end of the day, we really don't even know if the universe actually works in such a way to allow for this technology to exist as we envision it in the first place.

Gotcha. Is there no way to change & retain ASICs use?
EDIT: And ultimately, while it would suck for hardware owners, it is a necessity if BTC is to remain viable.
No, ASICs are hard-coded to a specific mining sha256d implementation. FPGA's however could become relevant again.

The event of btc-e.com being hacked, defaulting, disappearing and so on should be catastrophic enough to be easily determined. Also, I will not have to prove that I actually had 250 BTC in btc-e (I might have more or less at any given time). And no - I don't plan on hacking btc-e myself Why is it obvious this is a raging scam? Because no one with the sense to actually construct a legit scheme like this would ever let 250 BTC accumulate on BTC-e without doing something about it. If 250 BTC was too much for this person to comfortably keep in BTC-e he would've already done something about it, and if 250 BTC is just a small fraction of his total BTC holdings, then he wouldn't be soliciting this kind of arrangement in the first place. So basically the OP is soliciting funds to perform a transaction that, in the absolute best possible case scenario, is only happening because he's a moron!

You can't use bitcoin for buying stuff on the fly. Too much wait time cos too many conformations are necessary for it to be adopted by the mainstream brick-and-mortar stores. Full service Restaurants and bars do accept it cos you'll be sitting there a while. So yeah.. Any store where you normally would be in and out of in 5 minutes are never going to have any use for bitcoin. Those alts that were mentioned earlier are probably a better bet. In the long run, next generation currencies like Nxt with near-instant confirmation will likely be the staple for such transactions.
This entire statement is based on a complete misunderstanding of what confirmation actually means. For the purposes of a point of sale situation, simply seeing the transaction broadcast on the network is good enough.

The real long-term question might actually turn out to be "How will the IRS survive Bitcoin".

Hey. I'm a newbie. I've just looked at some blockchain display tools on websites that come back with a designation of invalid at points. Maybe I wasn't looking at the REAL blockchain but I'm not sure how I'd figure that out without buying a $10,000 computer and compiling all my own software from source code (after looking at it in detail). You do compile all your own software from source code, don't you?
I get it now, this is all trolling!

Gold has intrinsic value because it's a usable metal.
Bitcoin has intrinsic value because it's a usable product of hash computation. What's your point? Can you wear bitcoin on your neck? No. Can you send gold over internet? No. Which one is actually more useful? For me it's clear. It doesn't exist in the real physical world. It has value, but not intrinsic value. See this: Something has intrinsic value when it has value by itself.
Gold has intrinsic value, because it can be used as a component in electroncics, because it is beautiful and because you know others would want to buy it, it has a long history of acceptance.
By that definition, bitcoins have no intrinsic value. One BTC by itself is useless. What bitcoins do have is intrinsic utility similar to cell phones. One cellphone is useless, give a billion people a cellphone and a network and it becomes very - very useful.
In that situation, if intrinsic value is determined in (great) part by intrinsic utility, the intrinsic value will only go up for bitcoins.
These are all completely made-up fictitious internet terms and concepts.

Quark has something new. Lel.
It is still a scam, but the codebase is completly different. Watch yourself. But probably you can't even code... clone of primecoin No, Quark has its unique algorithm (different from Primecoin, although they both claim CPU mining). Many coins are cloning Quark. Quark's "unique algorithm" basically consists of throwing as much feces as you can at the wall and seeing what sticks! Seriously, 9 rounds of hashing 6 different algorithms may sound impressive on paper, but it does not solve either of the two stated design goals in reality. For example, the supposed resistance to FPGA / ASIC implementations is a complete fairytale, because nothing about the proof of work imposes a tradeoff due to memory bandwidth constraints whatsoever. The FPGA / ASIC resistance basically comes from the fact that nobody actually cares about Quark!

There are already invalid blocks in the blockchain, so I don't think you need to "force" a node to accept a bad blockchain. It has already happened. (A mystery to me, BTW). Also if you have a 2 million machine botnet accepting your bad blockchain and readvertising it as the longest, what happens? The biggest node I saw had only 1000 connections.
Are you suggesting that there are blocks on the main network consensus blockchain that don't have a valid nonce for the target difficulty?

Spending any non-trivial amount of money on any altcoin except Litecoin is absolutely certifiably insane.

I've seen a lot of post here about botnets that actually attempt to mine bitcoins. The authorities recently identified a 2 million machine botnet. Couldn't that present a totally different threat if the true purpose was to controll the network consensus? What if they all advertised the same longest (but unproofed) blockchain? How would the system counter that? How many nodes are there currently?
That's not technically possible, because each node independently verifies the blockchain. There is nothing that a botnet could possibly do that would force your node to accept an invalid blockchain. In a peer-to-peer network I dont see how hashrate makes a difference to consensus. Isn't every node equal? One node doesn't know how fast another node is. If they're all equal, then what is a "true" node? Isn't that the same as a "central authority"? Anyone know how many nodes there are?
Hashrate is central to consensus because it determines the probability of any given miner finding valid proof-of-work for any given block. Nodes achieve consensus by accepting the longest chain with valid proof-of-work. The node function and mining function are not the same thing.

all those shitty altcoin are here because of asic, blame it, they made bitcoin mining centralized
btc mining should have stayed with gpu
also people are really mad cuz they have missed the btc train
ASIC has not made Bitcoin mining centralized at all, it's just that so many people actually know about mining now that the competition makes it impossible to mine as a get rich quick scheme. Putting together a good GPU rig back when difficulty justified it cost just as much if not more than an ASIC unit today.

I think Bitcoin will rise steadily 2014. People needed the money for Christmas and new year so that's the cause of the crash in my opinion. Unless another big news will come for bitcoin (like the US bans the use of it or something like that) it is not going to crash and be worthless.
I dont think any government can ban it unless they unplug the internet. Its a protocol based on trust, utility and security and all 3 of those improve each day. The key to success is that some large business's (like Baidu in China) accept it and lend some legitimacy to it. Bitcoin can be banned, it would cripple the adoption of Bitcoin, but still some would use Bitcoin Outright banning Bitcoin forces governments to show their hand in a way that crushes the pretension that we are not in a completely totalitarian world, which is socially-desirable because it would encourage the overthrow of such regimes.

The coins that artificially encourage early adoption are just a scammy way of re-creating what happened with Bitcoin naturally.
Bitcoin was completely fair, Satoshi publicized it with the whitepaper well ahead of time, and anybody who wanted to could participate from day 1. Since Bitcoin was the first example of the kind of technology that could actually solve the Byzantine Generals problem, practically everybody just laughed at him and very few people took it seriously until years later.
Now that we actually know that a blockchain / proof-of-work actually works, we have a bunch of opportunists who either didn't take Satoshi seriously when they could've actually mined a ton of Bitcoins easily or just didn't know about it. Sorry, this ship has sailed!
