Hello, how long does it currently take to withdraw us dollar from Mt Gox via wire?


What if I liquidated bitcoins in Euros and ate the foreign transaction fee from my us bank? how long would that take, via wire

Hey guys, I am trying to calculate a market competitive premium for some options I'll be writing.

What software do you use to calculate single share options? Do you just do a normal calculation for a standardized option of 100 units and divide by 100?

How do you price in volatility on these exchanges?

Thanks in advance!

If a large portion of the network went offline right after a difficulty increase, this scenario could freeze the bitcoin network for thousands of blocks. Basically blocks would be found MUCH more slowly to the point of it being nearly unusable.

This exact scenario happened with terracoins a few month ago. Basically what happened was that someone pointed an ASIC at terracoins and this push the difficulty EXTREMELY high, and then they stopped mining, leaving the difficulty extremely high for 8 days and no terracoin transactions were able to be processed because it took an extremely long time for the remaining miners to process any blocks.


If two of the largest miners of bitcoin went offline, the entire bitcoin economy would be at a standstill for at least several days. Although with today's makeup, just a pool could go offline and all the pool members would continue mining at a different pool. But in a different scenario, ASICMiner could have a larger portion of the network and lose connectivity right after a difficulty increase, or 6 months in the future, a different company would have 100s of terahashes more and the same thing could happen.

This is less likely with bitcoin today, but it is a real vulnerability.

In terracoin's situation the remaining hashrate was only 1/10th of what it was after the ASIC bumped the difficulty up. This isn't currently a possible scenario with bitcoin. But one could imagine a party with some future 14nm sha-256 chips developed solely to prop up the difficulty and then leave the network, making it take months until the next difficulty adjustment, making blocks take hours or days to solve, rendering transactions useless.

What can we do about that? Terracoin has fast changing difficulty

I have 5.8 btc stuck in limbo somewhere, I sent with the .0005 transaction fee @ 14:55, it is now 16:23

hello, currently laws related to currencies are based on fiat economies and the ways fiat is transferred

these methods of commerce have no one-to-one relationship with how commerce is done in a blockchain based economy, and the way information about transactions is disseminated


perhaps existing legislation could address this by making a distinction between fiat based economies and blockchain based economies.

For instance, eventually almost everyone will have transacted with a convicted criminal with illicit funds in a blockchain address. In a fiat based economy there is no visible link but if there was a direct link you too could be implicated with the criminal in some jurisdictions. With a blockchain, using this logic, everyone could be implicated, blockchain just needs to be exempt from this logic

If transactions were moved "off-chain", would the main blockchain's blocks get the fees included in the blocks?

if so, how.

(Feel free to move this thread to wherever, but I think people are only looking at this in the securities section.)

I am buying AMC shares at 0.0005 each, off of the exchanges.

Thank you for your time. This will be done using John K's escrow if he is available.

Is there an order book that shows the international best/bid ask for bitcoin from multiple of the largest exchanges in USD?


I need a consolidated order book.

Most preferably I would like an android widget that displays this, without me having to manually switch the exchange I want to see, in the settings.


So does this already exist, is there an api service that provides this, is there an android widget that already pulls from this API?

BTC-E has had higher bitcoin/usd bids than Mt. Gox many times in the previous months, even with BTC-E's priced-in expensive withdrawal options. Its not apparent when this happens, and too many API's rely on Mt. Gox data.

This would be a US-based bitcoin market maker, adds liquidity to the order books of both the currency and futures and options market.

Needs a lot of capital for such a venture, any interest in this? This is something I mainly want to organize and begin discussions on, because there is a need for this.

Bitcoin trading volume is at a low as of time of writing. Larger market participants are unable to consider bitcoin with its low trading volume, thin order books, lack of liquidity and lack of hedging capabilities.

For a direct comparison, CBOE - Chicago Board of Options Exchange would be the model this company would be like.

Ideally this would be a market maker for existing exchanges, but the company would seek a maker-taker liquidity rebate model, that does not exist on any current bitcoin exchange.

This company could do its part in solving some of the growing pains of bitcoin by adding liquidity.

Anyway, I hope to open a discussion on it at the very least, to refine a potential offering.

There is very little liquidity on Mt. Gox and the volume, based on the time since clark moody's tracker starts is the lowest since ever.


A big order on Mt. Gox can really rip through the order book if someone wanted to. Again BTC-E price is currently higher than Mt. Gox making it probably the best international bid/ask

For members that have done trades with me and the company.

hello I would like to buy puts at flexible sizes on bitcoin.

I really need a *liquid* derivatives exchange

Hey guys, how do I use John K's escrow, is there a formal way? like topic and message of a PM to John K

well more immediately, someone wants to pay me with John K's escrow, so they should be the one asking but I also don't want to lose the sell or waste time. so it would be good to know regardless


I did a google search with mixed results, but maybe there is a sticky somewhere here that you denizens know about

[But will ship internationally. Willing to use John K escrow.]

edit this is sold.

edit:
this quickly turned into an auction, we are at:


1 @ 39 btc
1 @ 33 btc
1 @ 32 btc
1 @ 31 btc

wasn't prepared for an auction but I'll give this till Friday evening GMT -5:00

hello, so at this point everyone can repeat that scrypt is "memory intensive" and therefore no ASICs can be produced for that algorithm because it would cost too much


now that we have established that copypasta, lets talk details:

what kind of RAM and how much would it cost

what are the technical requirements for a theoretical system to be specifically good at hashing with the scrypt algorithm

for benchmarking purposes, 1000 times better at hashing with the scrypt algorithm, since scrypt is supposed to be 1000 more difficult than the SHA-256 standalone algorithm

Hello,

I have several pieces of hardware. Based on permutations would my luck improve in finding a block of 25 btc using all three of my machines solo mining

estimates say this could take 50 days before I find a block, but this is much more luck based than these estimates let on


thanks for any insight

I think my block erupter blade is resetting and not actually doing anything
