Many investments are rocks. When you let go, they will fall back to ground. Some are balloons. When you let go, it will rise to the atmosphere. It is not easy for many to distinguish between those two. Also the balloons are susceptible to pricks. Trade wisely.

Trade wisely, yes.

But this is a bad anology, you imply that a rock won't fall until you let it go, i.e., sell. Thats just not true. Often that rock is driving to the ground and you cant get your hand off it fast enough to stop from being crushed by it as it hits the gard pavement.

Here's the line for you: bulls makemoney, bears make money, pigs ge slaughtered. Don't be a pig!

The price will get a correction down to ~35USD/BTC. But in the long-term, if BTC were to stick as a widely-used international currency, I think we'll long for the days when it only cost 70USD.
Think about offshore banking and crime- I think that pretty soon they'll adopt BTC as a means of transferring large amounts of money and that will eventually lead to a much higher and stable exchange rate.

I think it will not go to 70 level but it reach that level. That will happen only if very bad news comes out on bitcoins.

Dude. Flashback Friday was yesterday. Get it!

It's flashback friday an actual thing? because there are a lot of good threads from years ago that are worth bumping as a reminder for newbies to see how wrong people was when people sold at ridiculous prices such as 15$. I remember a thread with a guy saying he was selling at that price and abandoning Bitcoin because it was "all over".

Imagine what happens if the price goes back up dramatically from this point and people still don't believe in Bitcoin.

That's right, the price is depends on the demand. if there are more bitcoin adopt come in, the price will rise especially halving time is next year Grin

demand is more than supply = price up.

I understand that the market reaches this consensus through buyers and sellers placing their bids and asks on the exchanges, but WHY is a Bitcoin worth that price?

If Bitcoins were at $50 right now we would all probably think that was completely reasonable. If they were trading at $1000 a Bitcoin we would accept that too. Do buyers just pick arbitrary sell prices in their head, and then sellers pick arbitrary buy prices, and then the market reaches a consensus? Does anyone actually have a good understand of this or is there no "good answer". Thanks.

The way to determine to determine the price is by using the money velocity equation:
V*M=nT (1)

where V is average velocity (how fast money changes hands in actual transactions), M is the number of money units, i.e., bitcoin - currently about 11m. nT is the nominal value of all transactions measured in BTC.

nT=P*Y where Y is the real value of all transactions and P is the price level (antiderivative of inflation level) which is inversely proportional to the value of the money, so nT=Y/val.

Whence

(1)=> V*M=Y/val => val=Y/(V*M) (2)

Lets put some values into this equation (2), note that I am just making qualified guesses now. Some people may very well improve upon this answer below:

Y is the real value of actual Bitcoin transactions, I say actual because many transactions in the Blockchain are just transfers between different accounts which have the same owner. Satoshidice transactions are real transactions, though, since they fulfill a market demand. I choose to measure Y in dollars. Let's just assume the Y is currently 20 times the value of the revenue of bitcoinsstore.com, so Y=20*400,000$/month=8,000,000$/month=96,000,000$/year ~100,000,000$/year.

I assume V=1/year which is close to that of state fiat currencies. Plugging this into (2) yields:

val=100,000,000$/(1*11,000,000)~9 dollar/BTC

This is a fairly low value since I have not accounted for speculation (buying because some expect BTC to rise in value comp. to $) and since I may have underestimated Y. Speculation can be accounted for in a higher Y and a lower V which both raise the value of "val".

I hope this gives you an idea of how to evaluate BTC's potential, though. It all depends on Y in the long run, i.e., how large the market for actual Bitcoin transactions will become in the future.

Regards,
Sword Smith

Edit: I want to point out that I see my estimate on Y as an estimate of the current value of transactions and by no means an estimate of the value of future transactions. The value of M is also highly debatable.

my opinion is bitcoin is worth a whole lot more that any recent prices we have seen. If you look at all the advantages of bitcoin such as freedom of money transfer, ease of use, low to no fee's, privacy, anonymity, security ect... Plus you add the finite amount of bitcoin available to the world 21 million you can do the maths. when there is 21 million users of bitcoin what will 1 bitcoin be worth?
when there is a world full of bitcoin users then what will bitcoin be worth?
Not that it is a good thing but bitcoin would be very useful and appealing to criminals. They estimate that crime turns over 200 billion dollars a year and growing. with 11 million bitcoin's currently mined and half of the crime turnover goes into bitcoin that leaves bitcoin at about $9000 each without considering that this big demand will push the price though the roof.
this is only one type of bitcoin user group.
Bitcoin is still a baby and needs time to grow, as new programs and services become available making bitcoin easy for everyone to use without needing to understand it people with use bitcoin without even thinking and it will be massive.
I used the crime stats not because I condone it in anyway but just as an example of a user group witch will use it regardless of law's and to show it's real value in a real world situation.
Bitcoin will be much bigger than crime, It is freedom returning to a slave monetary system. Everyone will be happy with this.

You cannot plot it with a linear scale, on that chart you posted one cannot see anything, its totally distorted because it over-exaggerates movements at higher prices and downplays the equally large movements at lower prices. Why do you bubble advocates always use such distorted scales for the y-axis? You do it because you want it to look like a bubble. Post it with a logarithmic scale like everybody else who is seriously analyzing the price history, then the relative price movements will be represented the same way in all price regions, it won't be distorted and then it won't look like a bubble anymore at all!

Actually, it's quite simple. If there is 10 million people wanting to have bitcoins worth 1$ and there is 10 million bitocoins, the price will be 1$

If they either want to have 10$ each or if there is 100 million of them, the price wil be 10$ etc..

How will it be in the future? Just find out how many want to have bitcoins, how much they want and then you know.

So what? What is the term "bubble" mean other than a word designed to give a negative connotation to a rise in price seen by the perceiver as illegitimate? So far, in Bitcoin, we've had two large moves: the first from about $1 to $30 and the second from about $13 to $70 (and who know if it's done?) Simply put, it's proven it's capable of multiple LARGE moves. Who's to say there won't be a third move or a fourth? In fact, the chart you posted could look insignificant in three years time. Like a blip. I don't care if it's a "bubble", I'm gonna ride it as far as it'll take me while you're sitting there going WTF!

I think the above answers on supply and demand, which we call Price Theory, is the best explanation on how the price is determined.

But, you are really asking what is driving increased demand...

1> Until the mainstream is using bitcoins, we are in the early adoption phase. Unless Bitcoins fail to take hold, which appears unlikely, demand will increase until the mainstream is using them to their full potential. This is, arguably, a long ways away. Thus, demand will continue to grow over the long-term.

2> Think outside the box (US). In Argentina, pesos inflate about 30% a year. They block purchasing US dollars to try to increase trading in pesos. One fundamental problem, then, is how do you save if your savings in pesos keeps losing value. Two options are buying buying hard assets like gold and buying bitcoins. There is also an underground market for US dollars that trades much higher than the official exchange rate (8 pesos per $1 instead of 5). The trick here is who wants to sell bitcoins for pesos? If you needed pesos to buy something, using bitcoins to purchase the pesos could add to your profit.

3> Continue to think outside the box (US). Italy and Spain watched Cyprus savings accounts become hostage to possible "tax" by the government, or theft as some circles choose to call it. The problem is that Brussels is pushing this tax on Cyprus. If Italy or Spain end up in the same pickle, the same Brussels will be crafting their bail out plan as well. If you live in these countries, you are now thinking about ways to shield your saving from government confiscation. Bank accounts are looking pretty vulnerable right now.

4> The safest savings. Imagine a world where wealth is measured in gold. Your biggest challenge, once you have it, is protecting it from theft. Your home can be broken into. So, you put it in a bank. But, banks quickly learn they can make loans on that gold. Plus, they can be robbed, too. But, while your deposits become ever safer from robbery, those loans create an increasingly vulnerable banking system. Along comes 2007, our wake up call, then problem after problem in Europe. Then Cyprus. You can buy gold, yes. But, then you're back to the beginning of all this. How do you protect your gold. Ironically, bitcoins can potentially be the easiest to protect asset on this planet. You can, for instance, break your private keys into 10 pieces, and scatter them across the planet.

Demand is, an will continue to increase. There are countless other examples. The key to remember is they are International. What happens in China, Argentina, Russia and Cyprus matters.

In the words of Falkvinge: "Bitcoin is a transactional currency. As such, it is competing for market share on the transactional currency market... When you know the size of the target market, and have an estimate for your projected market share, you can estimate the value of your product or service as a percentage of the value of the total market.

They aren't.
This is a speculative bubble, and people are buying them at this rate with the hopes to sell them later at a significant profit.

People are buying them at this rate with the hopes to sell them later at a significant profit or as I see it, also buying Bitcoin's as a saving to avoiding inflation.

In which case if the used base is growing, it may not be a speculative bubble unless the "Bitcoin Nouveau riche" cash out too quickly, instead of slowly dispersing the currency, or the speculators decide to sell there Bitcoin at a significant loss.

Does anyone actually have a good understand of this or is there no "good answer". Thanks.

I don't know the actual numbers, no one can, but I have a principled guidelines based on a rough mental picture obtained as a result of something my wife callas a Bitcoin obsession.

If M1 money supply = BTC market Cap
And
US GDP = BTC GDP
And you were to drawer a similar relationship to the two GDP's then you would expect the price to be around $2 per Bitcoin, at this time. The "market" aside, that's what the intrinsic value of Bitcoin as a medium of exchange, could arguable be.

Given my principles have cost me a small fortune - allowing me, with good reason to sell out in the low teens, I have changed my principals.

My new principled guidelines (emphasis on principled) see human nature as the driving force, it is more refined and has evolved surpassing that of our ancestral apes, who once picked up shiny objects and fought over them, eventually refining an interconnected society based on trade and plunder with one of the most durable shiny elements gold.

Now I see value in the finite aspect of Bitcoin, as the shiny gold we so all longed for is locked away in volts and we have fulfilled our desire for shiny objects through market forces that have lavished us with new cars, cell phones or Charismas cracker ornaments.

So we buy Bitcoin's, because there are only 21M of them and he who has the most wins, and it doesn't matter what they cost because you won't tell anyone how many you have anyway. This will go on for generations, all the while desire and greed will be held in balance and provide socially with a p2p socialist managed savings system that cannot be manipulated by any other force but that of the lack of desire and greed. And so that is how we get to the price today.

One can view it from another point of view:

The minimal bitcoin unit is the "satoshi", which is 0.00000001 "bitcoin".
In most currencies the minimal unit is the cent (0.01 $).

1 satoshi is worth only 0.0000007 USD, or 0.00007 cent.

1 mBTC, which is 1/1000 BTC and 100000 satoshi, is about 7 cent.

The price of bitcoins reflects what people expect to be able to get for them at some point in the future. I am willing to do work for 1 btc today because I expect I can use that 1 btc to pay for the things I need tomorrow. I am willing to pay $70 for 1 btc today because I expect I can get at least $70 worth of stuff tomorrow. Somebody sells me that 1 btc today because they need my $70 to pay for things like power bills or taxes or a new car.

The exchange rates are a little outdated in this example, but the point stands:

Quote from: DannyHamilton on February 24, 2013, 05:59:56 PM

The "price" of a bitcoin is exactly what someone somewhere is willing to pay for it, and someone else is willing to sell it for.

MtGox provides a place for people who want to buy bitcoins and people who want to sell bitcoins to find each other.

Example:

Albert has 100 BTC. He needs to pay his electric bill and the electric company doesn't accept bitcoin as payment. He decides to convert some of his bitcoin to USD. Albert logs on to MtGox and creates a limit order offering to sell 10 of his bitcoin for $33.45 each. He is not willing to sell the bitcoin for less than $33.45 because at any price less than that he'd rather just hold on to the bitcoin and pay his electric bill with other funds.

Bobby only has a two bitcoin that he purchased at $32.50 each. He decides that he doesn't really want bitcoin anymore, but he doesn't want to take loss. He logs on to MtGox and creates a limit order offering to sell his two bitcoin for $32.55 each.

Carl has just received his paycheck. After paying his expenses he has $200 left over. He decides to purchase bitcoin with this money. He feels like the exchange rate might drop a bit and so to get them as cheap as possible, he transfers his money to MtGox and creates a limit order to purchase 6.25 BTC at $32 each.

David just received an inheritance of $10,000. He decides he'd like to hold the entire balance as bitcoin. He has seen the exchange rate varying between $31.50 and $33.50 lately, and hopes he can get the entire balance at $31.50. He creates a limit order at MtGox for 317.460317 BTC at $31.50 each.

Earl is in a hurry. He just wants to buy something from SilkRoad right now, and he'll take whatever the current exchange rate is. He needs $60 worth of bitcoin. He transfers his $60 to MtGox and places a market order for $60 worth of bitcoin. MtGox sees that the cheapest offer to sell bitcoin at their site at the moment is Bobby's offer of 2 bitcoin at $32.55 each. MtGox transfers the $60 from Earl to Bobby and at the same time transfers 1.84331797 bitcoin from Bobby to Earl.

At this hypothetical moment the current bitcoin price is therefore $32.55, since that is the most recent exchange that has occurred.
Earl now has 1.84331797 BTC
Bobby now has $60 and 0.15668203 BTC still available to purchase at an exchange rate of $32.55 per bitcoin.

Now Albert suddenly realizes that he doesn't have enough other funds for his bill. He needs $334.50 right away to pay the bill, and needs to sell the bitcoin quickly to get the necessary money. Albert cancels his limit order and places a market order to sell $334.50 worth of bitcoin. MtGox sees that the most expensive offer to buy bitcoin at their site at the moment is Carl's offer of 6.25 bitcoin at $32 each. MtGox transfers $200 from Carl to Albert, and 6.25 bitcoin from Albert to Carl. Since Albert still needs another $134.50 worth of bitcoin to fulfill his order, MtGox sees that the next highest offer is David's offer of 317.460317 BTC at $31.50 each. MtGox transfers 4.26984127 BTC from Albert to David, and $134.50 from David to Albert.

At this hypothetical moment the current bitcoin price is therefore $31.50, since that is the most recent exchange that has occurred.
Albert now has the $334.50 that he needs, and still has 89.4801587 BTC remaining.
Carl has picked up the 6.25 bitcoin that he wanted, spending the $200 that he wanted to spend.
David has purchased 4.26984127 for $134.50, and still has a limit order out there waiting to be filled for another 313.190467 bitcoin at $31.50 each.

You'll notice that there are actually many "prices" for bitcoin. There is the price that each individual is willing to buy or sell their bitcoin for. Some of the more often quoted prices are the "current Ask", "current Bid" and "most recent exchange".

Prior to Earl coming along, the "Current Ask" was Bobby's $32.55 that he is asking to sell his bitcoin (the lowest price anyone is willing to sell for at that time).
The "Current Bid" was Carl's $32 bid to purchase bitcoin from anyone willing to sell that cheap (the highest anyone is willing to pay to buy at that time).

I like that. Its a perfect demonstration of all the kinds of players and participants in any given market, not including brokers, speculators, traders, investors etc. and each one of those has their own price, which represents to them, value.
A traded price could be explained as an agreement of value between two parties, at that time.

They aren't.

This is a speculative bubble, and people are buying them at this rate with the hopes to sell them later at a significant profit.

Economics 101

"I want that."

"I like this tho."

"I'll give you this much for it."

"I'll only sell it for this much."

"Okay deal."

Economics 102

"I really want that."

"I really like this tho."

"I'll give you more than I used to give you for it."

"Okay."

Economics 103

"I don't want this that much anymore."

"I really want to sell it tho."

"I'll give you this much less than I used to."

"I don't like it, but I'll take it."

I now congratulate you for completing these courses in "Why the hell is this priced this way?"

The exchange rates are a little outdated in this example, but the point stands:

The "price" of a bitcoin is exactly what someone somewhere is willing to pay for it, and someone else is willing to sell it for.

MtGox provides a place for people who want to buy bitcoins and people who want to sell bitcoins to find each other.

Example:

Albert has 100 BTC. He needs to pay his electric bill and the electric company doesn't accept bitcoin as payment. He decides to convert some of his bitcoin to USD. Albert logs on to MtGox and creates a limit order offering to sell 10 of his bitcoin for $33.45 each. He is not willing to sell the bitcoin for less than $33.45 because at any price less than that he'd rather just hold on to the bitcoin and pay his electric bill with other funds.

Bobby only has a two bitcoin that he purchased at $32.50 each. He decides that he doesn't really want bitcoin anymore, but he doesn't want to take loss. He logs on to MtGox and creates a limit order offering to sell his two bitcoin for $32.55 each.

Carl has just received his paycheck. After paying his expenses he has $200 left over. He decides to purchase bitcoin with this money. He feels like the exchange rate might drop a bit and so to get them as cheap as possible, he transfers his money to MtGox and creates a limit order to purchase 6.25 BTC at $32 each.

David just received an inheritance of $10,000. He decides he'd like to hold the entire balance as bitcoin. He has seen the exchange rate varying between $31.50 and $33.50 lately, and hopes he can get the entire balance at $31.50. He creates a limit order at MtGox for 317.460317 BTC at $31.50 each.

Earl is in a hurry. He just wants to buy something from SilkRoad right now, and he'll take whatever the current exchange rate is. He needs $60 worth of bitcoin. He transfers his $60 to MtGox and places a market order for $60 worth of bitcoin. MtGox sees that the cheapest offer to sell bitcoin at their site at the moment is Bobby's offer of 2 bitcoin at $32.55 each. MtGox transfers the $60 from Earl to Bobby and at the same time transfers 1.84331797 bitcoin from Bobby to Earl.

At this hypothetical moment the current bitcoin price is therefore $32.55, since that is the most recent exchange that has occurred.
Earl now has 1.84331797 BTC
Bobby now has $60 and 0.15668203 BTC still available to purchase at an exchange rate of $32.55 per bitcoin.

Now Albert suddenly realizes that he doesn't have enough other funds for his bill. He needs $334.50 right away to pay the bill, and needs to sell the bitcoin quickly to get the necessary money. Albert cancels his limit order and places a market order to sell $334.50 worth of bitcoin. MtGox sees that the most expensive offer to buy bitcoin at their site at the moment is Carl's offer of 6.25 bitcoin at $32 each. MtGox transfers $200 from Carl to Albert, and 6.25 bitcoin from Albert to Carl. Since Albert still needs another $134.50 worth of bitcoin to fulfill his order, MtGox sees that the next highest offer is David's offer of 317.460317 BTC at $31.50 each. MtGox transfers 4.26984127 BTC from Albert to David, and $134.50 from David to Albert.

At this hypothetical moment the current bitcoin price is therefore $31.50, since that is the most recent exchange that has occurred.
Albert now has the $334.50 that he needs, and still has 89.4801587 BTC remaining.
Carl has picked up the 6.25 bitcoin that he wanted, spending the $200 that he wanted to spend.
David has purchased 4.26984127 for $134.50, and still has a limit order out there waiting to be filled for another 313.190467 bitcoin at $31.50 each.

Prior to Earl coming along, the "Current Ask" was Bobby's $32.55 that he is asking to sell his bitcoin (the lowest price anyone is willing to sell for at that time).
The "Current Bid" was Carl's $32 bid to purchase bitcoin from anyone willing to sell that cheap (the highest anyone is willing to pay to buy at that time).

Expectations! Only expectations! The exchange rate will fall down, if bitcoin owner some day realize that this expecation cannot be fullfilled. I think Cypres was the main reason for the recent price raises. You read of "robbing". People just realize that no investment is without risk. But is Bitcoin? No! It isn't! I am a really big fan of Bitcoin but the today exchange rateis too high. You know when Amazon or Walmart had 5 days ago pronounced they will accept Bitcoin the exchange ratewould be even to low. But nothing of that kind happened...

I hope the price will crash, so I can buy

PS: I just realiszed that "course" does not mean "exchange rate" (same word in German). damn it! I'm glad to realize that now. Otherwise my post would have not make much sense^^

As most commodities btc is worth whatever someone will pay for them.

The increase or decrease in btc supply and demand that would influence the btc price depends on how many dollars, or other currency, a buyer is willing to pay for btc versus the amount of currency a seller is willing to accept for his btc.

The willingness of all these parties to change paper currency for btc and vice versa is what determines the price of btc in relation to each different paper currency respectively.

I myself, believe theyre worth more than an ounce of gold. Eventually I think well see the value settle in at $400-$800/coin.

I understand that the market reaches this consensus through buyers and sellers placing their bids and asks on the exchanges, but WHY is a Bitcoin worth that price?

If Bitcoins were at $50 right now we would all probably think that was completely reasonable. If they were trading at $1000 a Bitcoin we would accept that too. Do buyers just pick arbitrary sell prices in their head, and then sellers pick arbitrary buy prices, and then the market reaches a consensus? Does anyone actually have a good understand of this or is there no "good answer". Thanks.

You actually answered your own question. "Consensus through buyers and sellers" is what creates the exchange rate which is determined at the exact moment of a given transaction. Now, to answer "why" the consensus has declared Bitcoin is worth ~$70 USD you need to look at utility. Why is Bitcoin more valuable respective to other currencies? It's because of its fundamentals. Bitcoin is generally considered to be more useful than other currencies as a means of transferring/storing wealth, and so the general consensus is that its value is higher. Moreover, I think it's safe to say that Bitcoin being valued at ~$70 USD is currently the result of speculative consensus. For example, with all this talk about Coinlab taking over operations for Mt. Gox in the USA, people may be speculating that investors will find Bitcoin very useful as well, and so we predict Bitcoin's value will continue to rise as its utility is recognized by additional others.
