Interesting observation, MAbtc. Thanks.

To answer an earlier question: myself, I'm on vacation currently, and, yes, I personally do notice a bit of "analysis fatigue".

That said, I am watching, peripherally, if selling pressure is substantially increasing to the point where the current price level 500s to 600s breaks down , but I don't see that happening so far. In absence of that, I am watching the development through the fibonnacci lense I posted about a few pages ago. From that perspective, we're still on course for leaving the 2013/14 bear market behind.

That said, you seem to see the situation rather binary:
For one, the largest pools that could in principle collude in an attack have shown absolutely no sign of interest in doing so.

[blah]


Way to butcher my argument...

Carry on without me then.
1464  Economy / Speculation / Re: The BTC price is too high for it's current security model on: July 26, 2014, 08:01:52 PM
I agree with the analysis, r0ach. Mostly. changed my mind. OP has a valid point, wrapped up in a hysterical and sensationalist presentation.

De-decentralization is, in my view, the biggest (technical) challenge BTC faces at its current stage. Needless to say, just ignore the peanut gallery calling you a troll - shooting the messenger is always easier than accepting an unpleasant message.

That said, you seem to see the situation rather binary: either the network is decentralized, or it is not. I believe however that, taking into account human elements, i.e. not just looking at centralization/decentralization as a technical property of the network, we're very far from BTC being completely "centralized".

For one, the largest pools that could in principle collude in an attack have shown absolutely no sign of interest in doing so. In fact, them doing so would almost certainly be economically damaging to them. And other than a hypothetical attack, they don't hold special "voting powers" that grant them a disproportionate influence on decisions.

Second, the large pools are comprised to a large degree of individual miners, so the situation is different from, say, 2 or 3 large individual operators holding the same computing power as the currently largest pools.

Third, you mentioned it yourself, technical solutions (or proposals) exist, p2pool one of them. Right now, the incentive isn't there yet to fully switch to an alternative mining model, but I just don't see it as an urgent failure case either: if any form of abuse of a majority of computing power becomes known, the network's value will be damaged, I'm sure, but at the same time, the incentive to enforce decentralized mining will also be there finally. In the absence of such abuse, there is no urgent reason to switch (which is probably why we're not doing it). I'd prefer miners (and users, and investors) would think a bit more long term and provide more incentives to make the transition to a decentralized mining model (brought that up in a thread of my own), but until we're actually getting there, I fail to see how the current state is so bad that it prevents actual usage of the network for a pretty big portion of, say, online payment processing. It's not as if the alternatives are more secure, or less centralized. In fact, they're substantially worse on both counts - even if BTC security and centralization is not at its optimum.

I'm not talking about the distant future of how big Bitcoin can grow. That is irrelevant. I'm talking about the present and immediate future. Some of these companies may hold a small amount of Bitcoin but you have to admit you are living in a Bitcoin bubble fantasy if you think most of these big vendors are holding onto their coins.

It's going to be a long while before the majority of big vendors don't auto trade most of their bitcoins into fiat. That's just a simple fact.

What we are going through is a painful transition period that I don't think many people saw coming a year ago, where each new major vendor announcement is actually ironically adding to Bitcoin selling pressure.

That said, everything I've written is of course moot if something causes an epic spike in buying pressure. Some say the ETF's and Wallstreet could spearhead the pump - myself, I am not so sure.

You may misinterpret me as bearish, I'm not. I have significant BTC holdings (all I will say is greater than 3 digits) and I'm a true believer in the long term which is why I hold. But I have a lot of uncertainty about the short term. I will be the first to go nuts if we hit $5k anytime in the next couple of years. I just don't see much happening in 2014 in terms of another crazy price rise like we've seen so many times in the past.

We shall see.

Complete agreement, on each of your points - long term: huge potential, short term: selling pressure outweighs buying pressure, mid term: not 100% certain what the next reliable "new fiat event" will be.

It looks like this narrowing range has to end in 30 hours.  Breakout heading up?

Or it'll ignore your "range" and continue trading sideways.  IMO, just because lines on charts cross at near arbitrary points does not mean that the price must necessarily do something at that crossing.

Or it'll do with a pretty high likelihood what it usually does once volatility goes down as much as it did now, and things get interesting again in a few days, maybe a week.

1469  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: July 21, 2014, 08:07:12 PM
Of course he is right, to a degree. Quantitative and technical analysis are useless unless integrated into a broader narrative (see S&P's models for rating mortgage backed securities back in 2006... the math wasn't wrong but it existed in a vacuum away from the broader narrative so it didn't appropriately capture the full range of contingencies). The question is, which one should lead (and is this a fixed answer)? Should you come up with a narrative and the test it against the technical analysis? Or should you use the technical analysis and charts to try to identify a trend and thereafter come up with an explanation? Or do you just entirely wing it by your balls, like most of us, and then come up with a series of post hoc rationalizations thereafter to explain why you did what you did so you can sleep at night.

P.S. -- Late August/early September should be a great time. It is possible we'll get the ETF by then (probably not, but possible), the broader economy usually starts to hit the s----er around this time (far enough away from tax return spending sprees and Christmas with no holidays coming up), and, most importantly, student loans drop. The latter, I think, would be an even bigger deal if we had a less sketchy swaps market. Imagine, if you are a student, being able to at least somewhat safely secure a fixed rate on the student loans dedicated to living expenses several months down the road (because it all hits at once) and as such being able to counteract the impact of interest accruing during your studies (for graduate students that happens). It really is too good to be true and people would find a way to get screwed, but it would be nice.

Oh yea, and actually most importantly, China's economy is starting to look terrible and their social institutions appear to be fracturing. Yea, we'll get a run.


Oooh, good newbie post. Followed Smiley

part of the reason why the current uptrend drags out like it does is because the market is increasingly professionalized: in the absence of ... (i.e. a new fiat floodgate...), the rational thing to do is take small profits early rather than hope for larger profits later.

That dynamic is providing energy to coil the spring for the next leap.  It works until it doesn't work.  The scalpers pick up the nickels, while the hodlers ride the steamroller.  The scalpers end up 50% in on average, or less if they short.  When the game shifts, that's a lot of capacity that needs to be filled suddenly in order to tag along for the upthrust.  We've seen this switch flip a few times since the GBL (Gox bankruptcy low).  One day it will stick in the On position, and money will flow until the circuit breakers blow.


I didn't say it's a long term stable state, did I? But for now, it seems to be the "small profit takers" that run the show. Until, indeed, the switch is flipped again and we see another "resistant" run-up. Which might take a while.

Before that, I expect a small scale version of the same dynamic, but one that is still sensitive enough to the profit takers' actions. Say, another week or more of the current sideways, maybe even a re-test of lower levels, and then another leg up to 800, 900.

I feel there's a certain level of cognitive dissonance rampant on this forum: everyone welcomes the "free market" and "doing exactly what you think is right", but when it applies to BTC price, those who sell early rather than wait for a much higher price level are considered as acting almost anti-social.
We're in the midst of a civil war of sorts, with Bitcoin currently serving as the battleground.

On one side, there are people for whom Bitcoin is a succession movement (from fiat). On the other hand are the people who are working to maintain fiat hegemony.

The two groups have opposing goals, so naturally they don't see eye-to-eye.

Agreed. I'd call that the "internal" view, and I actually can respect it. To some degree, social movements, successful social movements probably have to selectively ignore reality to a degree in order to gain traction.

But when I want to make an informed trading decision, I need to take an "external" view, one that doesn't take into account the higher goals of the Bitcoin movement, but only considers the objective reality of the market situation (as in: the likelihoods of certain outcomes). This being the speculation subforum, I sometimes would hope for a bit more tolerance of this type of analysis.

We went up 3 dollars so people have to take their 20 bucks profit you know.

I was just reading some garbage over on reddit that a self-described "non-professional" market trader with 25 years of experience posted.  It blew his mind at how the people trading this market had no idea what they were doing.  One point in specific, he noticed that people continue to want the price to crash so that they can "buy back in".  That, coupled with the apparent inability for people to let their winners run caused him to speculate that if/when Wall Street level traders do show up, that the "day tradurrz" of BTC right now are going to get chewed the fuck up.

I can't wait.

Wishful thinking. If anything, I believe part of the reason why the current uptrend drags out like it does is because the market is increasingly professionalized: in the absence of a strong "irrational" trend towards a new ATH (i.e. a new fiat floodgate opening and thousand of new investors/speculators/users entering the market), the rational thing to do is take small profits early rather than hope for larger profits later. Why? Because the same incentive exists for the other market participants, so if you're waiting too long for your profit of n%, I'm going to jump in and take a profit of n-1% and will be happy (and you won't make a profit any more at all).

tl;dr tragedy of the commons effect - right now, the individually rational thing to do is take small-ish profits rather than hope for the "big one".

I have cash sitting on an exchange now.  I almost bought, thinking we might see $630 today.  Then I saw the slippage would take us ~$627, which would send all of the traders into a selling frenzy and drop us right back at $618.  I said screw it.

You are right, what they are doing is is rational.  And they are screwing up the market right now, at least until we get higher volume.  I am not a fan of daytraders and hope they get eaten up by the bubble.

Which is where we differ in opinion then.

A "market" is, by most interpretations I'm aware of, based on the premise that (aggregated) individual rationality is the best way to appraise/value stuff. So if the "daytradurz" decide that, right now, it is the time to take small profits, who am I to scold them for it?

hi,

bitstamp changed bank again?  Huh

just to make sure.

previously was unibanka.

Same bank as always for me:



think it was changed to a different bank.

The screen cap is from the day I posted it, should have mentioned that.

Conclusions: it seems for some user, the bank is still Unicredit, and for some, it is now Raiffeisen.



@hazek

Could you please clarify if you are changing banks (for everyone? for some users?). Changing the banking details (if only for a subset of users) is a big enough deal to announce it, I believe.
1475  Economy / Speculation / Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion on: July 20, 2014, 11:13:03 PM
One of the things that make me skeptic of Technical Analysis (TA) is their general reliance on high and low points to determine trends and such.

Highs and lows are very noisy statistics, that may depend on a single decision by a single trader.  So much so, that even for exchanges that track each other very closely  (like Huobi and OKCoin), trend lines that connect highs or lows may be very different depending on which chart one uses -- even increasing/converging on one chart, while decreasing/diverging in the other.

Basic statistics says that the weighted mean a much more reliable parameter than high, low, open, or close; and a weighted least-squares-fitted line is much better than a line connecting any of those points.  To quantify the size of deviations from the mean or the fitted line, the standard deviation is much better than the high-low difference.

Median (and averages in general) are used in TA, but you are right, a lot of trendlines are largely based on extrema. I disagree however with your claim that the latter are too noisy to be useful: you seem to apply the insight from other fields were a noisy, sparsely populated parameter is best avoided. Two arguments why this insight can't just be applied 1:1 to trading: a) price extrema are the result of trades "eating" through the order book first, i.e. they are the conclusion of a longer, motivated process, not a randomly generated "blip", b) the knowledge what the exact maximum/minimum price some human (or his algo) was willing to trade for is not irrelevant or meaningless at all. I understand that from a purely statistical point of view, your argument makes sense, but taking into account that we are trying to model human behavior, not, say, bacterial growth, not everything can be carried over as straightforward, I believe.
1476  Economy / Speculation / Re: Let's Backtest Some Indicators on: July 20, 2014, 09:02:53 PM
re: SAR

I tried using the SAR myself, but find it alternatively too lagging and too "trigger happy" i.e. yielding too many, often unprofitable, signals. There's one positive observation I made however: since it is a momentum indicator with a "built in" price target, it can be useful for exiting a trade on a rebound, i.e. say I sell based on some indicator combination, buy back short term because I determine the "bottom is in", and then exit the trade = sell when price hits the SAR target. Usually relatively low time resolution, between 1h and 12h.


EDIT: A suggestion: since most of BTC traders trade to increase their BTC holdings, it would make sense to calculate profits and losses in BTC, rather than in dollars.

I thought the same at first, but then I came to the conclusion (please correct me if I'm wrong): a USD maximized holding and a BTC maximized holding are equivalent, as long as you just tack on one final 'buy' order to the end (i.e. calculate how many coins the final USD value buys you). Correct?

To see why: imagine you don't take a trade that is suggested by the tested system, and that turns out profitable. Your BTC value will be equal, but your USD to buy coins is higher at the next signal, so being USD optimal is equivalent to being BTC optimal. The only difference is that the final value of the holding is given in USD, so convert it to BTC according to current price.

@l_m_b_t Not entirely sure I understand your point about needing to include position sizing and curve fitting because of calculating BTC holdings. Then again, maybe I misunderstood wary's question.

We've been at this price the last few weeks, something has to give soon!

Agreed. Lowest daily BBW since ages - below 0.06, last time that happened was September 2013 iirc. It'll resolve soon, I'm sure. Not equally sure though in which direction. :/
Where did you get this reading? It's 35 on bitcoincharts.com.

Didn't even know btcwisdom shows bbw. Or you're simply doing [upper bb] - [lower bb]? If so, I suggest to use tradingview, which (to my knowledge) normalizes width to current price, making it comparable across price levels. Otherwise the statement "the lowest in year" would be even more impressive, but also kind of meaningless since with price increase absolute width also increases.
