Very good analogy! I like analogies Tongue

Don't discount the composition of that hashing power though.  Individuals mining today on their gaming rigs are getting squeezed out by difficulty increases versus a stable exchange rate.  They aren't going to be buying FPGAs so the operators of these larger GPU farm ops and 25 ghash/s mini-rigs will representing a greater and greater share of the hashing.

It would take a drop of something like 95% or a rise of something like 5000% to materially change the strength of the network.

That's the key point.  It like having the equivalent armed snipers every ten feet around a Fort Knox protecting only a few bags of pennies, nickels and dimes located inside.  Send half of them home and the pennies aren't left any less secure than before.

Shame on everything; regret nothing.
with those tiny FPGA rigs, there will be a shitload of people mining for free at their work

it should keep the price low

^Word.

Hopefully the supply of FPGA rigs will increase with demand...  Undecided to keep price of the rigs affordable...

Are you completely unfamiliar with the concept of burden of proof? Are you some kind of creationist or something?

As an 8 month+ miner I have to decide whether I finance that ASIC / FPGA rig with earned Bitcoin or pour in new money.

Summer is awfully unbearable within say 10 feet of 10 GPUs.  Maintenance, cooling, and space constrain are adding up making it an unprofitable waste of time beyond 2-4 (GPU) aka. single gaming rig.

Any moderately tech savvy investor (50k$ & more) looking to get into BTC will choose ASIC/FPGA boxes and will buy a few cheap BTC. (before the halving)

Overall the network will only be stronger and will be able to tolerate temporary drop to even 50c per BTC
I applaud BFL, LargeCoin and the likes for making this possible.

How about this:

Difficulty will rise from new technology (tons of gamers with new gpus, plus fpgas) and panic not to get left behind, some people mining at a loss regardless.
Prices drop because of hoarded coins from the early years being dumped on the market. (They hold out this long, "now or never")

I'm not saying this will happen, but just to remind you guys that tons of scenarios are possible. Don't freakin act like you have the magic crystal ball.

I am looking forward to buying a bunch of mining equipment at firesale prices after the reward drops.

Bitcoins are completely durable. A fully anticipated decrease in supply of a durable good cannot cause price to increase any faster than the real interest rate (1-3% per annum). If not, then speculators would want to invest in the durable good now, store it, and sell it at a profit after the supply drop. Competition among speculators drives the expected price increase down to the real interest rate. Any price effect due to falling block reward is already loaded into the current market price.

If the supply decrease was unanticipated or bitcoins were not durable, then this would be a different story.
It's not this simple, for one simple reason. Bitcoin market is so volatile for a large number of reasons that you can't look at this in a vacuum. If speculator x thinks the price might go down in the near future for a reason not related to this, he is not going to be buying now. I don't believe that this particular event is well priced in at this point. It will become priced in once this event is a bigger issue in people's minds. Right now it's still far away, so far in Bitcoin time that for all we know we might have a super bubble and a bust before it even happens.

To hammer my point in clearer, it's easy to anticipate a resulting price increase because of the reward drop. But from where? From where it was before. Here is the problem, we don't really know if a price of $5 is high or low. Maybe we're at $3 in August, good luck for those who priced in the price increase now. Bitcoin is so full of questions that it would be sort of super bullish to price in the reward drop price increase at this point because it's not certain we're even this high in the months before the drop.

So I'd say that people buying now are buying for a wide variety of reasons, this one in particular having little effect. In the months before the event, many will be buying solely for this reason. That is the difference.

Congrats to cunicula for providing a serious reply. However, I'm not sure if his analysis is fully valid in this case. The supply can't be anticipated -- a large speculator could already be holding a large number of Bitcoins and refuse to tell anyone when (if ever) she'll sell them. His earlier point (about inertia) has merit because there could be lots of those speculators, and since each could be similarly unpredictable, the supply is likely to get averaged out anyway. Nonetheless, there is a difference between anticipating the creation of coins, versus anticipating the availability of said coins.

All anyone ever does in this Speculation sub-forum is shout "FUD FUD FUD!"... It's why I usually don't bother reading it.

That is the difference. It does add to the overall bullishness of already bullish market players but closer to the event this alone will cause significant rallies because people expect that. It's a self-fulfilling prophecy, just like everything else in an environment like this.

also, we should all probably just put cunicula on ignore because all we're doing is bumping this FUDlicious thread.

I agree. My OP was definitely FUD. But I'm not trying to trick anyone. I just wanted other people's opinions and theories.

Bitcoins are completely durable. A fully anticipated decrease in supply of a durable good cannot cause price to increase any faster than the real interest rate (1-3% per annum) + a risk premium for holding bitcoin. If not, then speculators would want to invest in the durable good now, store it, and sell it at a profit after the supply drop. Competition among speculators drives the expected price increase down to the real interest rate + risk premium. Any price effect due to falling block reward is already loaded into the current market price.

If the supply decrease was unanticipated or bitcoins were not durable, then this would be a different story.

EDIT: include risk premium

Well then he needs to take a number like the rest, he has plenty of company here, it's rather like a support group without any trained guidance or oversight  Wink

Fear based thinking is characteristic of much of what I see pass for discourse on this forum. That's one reason why FUD is such an appealing concept to scared little sheep.

Seriously kiddies, your life is as likely to be a fucked up disappointment that you will regret every day as it is to be anything else, and no matter that, you are likely to die painfully in complete hopelessness and slide down that long gray tunnel into forever darkness without ever knowing why. Oh, and you can't take it with you, even if it is a deflationary currency  Wink

It's impossible to know how the block reward drop will affect everything exactly but talking about "failing" is absolute FUD.

This talk of FUD is such bullshit. Explain why it won't happen asshat. Don't just call it FUD. That is just so weak!

The price will rise...

Anyone who knows any economics realizes that there is no reason to expect more than a minuscule price increase (say 1-3% per annnum) from the drop in block reward. Adding a healthy serving of ass to your reply does not lend you credibility.

(addressing the audience) You should take these kinds of bullshit arguments as a tacit admission of extreme weakness.

I don't think there's any question that if the price does not double immediately after the reward drop, lots of miners are going to drop out.  Whether somebody maliciously takes advantage of that, there's no way to know.  With only more efficient miners left over, assuming the price doesn't jump up enough, then I suspect the price will continue downward as the more efficient miners can tolerate lower prices and remain profitable.

I think there's a good chance this scenario happens as people will probably price an increase in well before the reward change in anticipation of a possible price increase, thus there won't be a subsequent and sufficient price increase after the change.

Why should people feel the need to pay twice as much just because miners aren't earning as much? Halving the block reward doesn't make bitcoin twice as valuable, and nobody owes you free money for mining.
Block reward halves, miners mining at a loss stop mining, difficulty drops. Simple.

Ditto
And they restart mining the next week when they realise the difficulty has dropped enough to make it profitable again? There are a few "what is the meaning of Value? 101" threads around the place.

Cutting a very long story short:
Bitcoin value for miners ~= Cost + small personal reward.
Bitcoin value for everyone else ~= 1001 conveniences + psychological factors.
In other words, price is very elastic.

So if miners cut the supply, the users will go all ape-shit and pay more Wink

He even wanted to be paid to answer questions. Too bad claiming you know it better won't just do it in forums. If you don't want to educate others without being paid for it you shouldn't be on such a forum.

I would gladly pay for some of his sage wisdom. Unfortunately, I'm kinda broke at the moment -- all my funds are tied up in a business venture, and in order to access them, he would need to send me a donation of sorts (see address below  Wink ) to cover the administrative costs of unwinding part of that venture prematurely.

The thing is, difficulty lags behind the hash rate (correct me if I'm wrong). So at the very least it will introduce a jolt where new coins suddenly more expensive to produce, without a corresponding decrease in difficulty. That "while" might be a few days, or it might be several months. If one has a look at historical difficulty charts, to me it looks like the difficulty is still oscillating from last year's bubble.

I am not saying difficulty (hashing power) and price won't oscillate.  They certainly will.  I also think volatility (both in terms of hashing power and price) are likely to increase as we move through this "event".  I am just saying even a change from 10TH/s to 5TH/s doesn't materially change the strength of Bitcoin. 

Fair enough. When it comes to leading vs lagging indicators, do you see any overt mechanism/cause for increased volatility leading up to the changeover? The only obvious thing I can see is the psychological uncertainty!
