In other words, final stage of growing up is actually a recognition that you give a meaning to the universe (not the other way around), and that you actually have the tools to realize the meaning in your life and to refine it. Worrying whether there exists or does not exist someone who set it up in this way and what is their intent is then besides the point. Both points of view (God does exist/doesn't exist) may help different people to achieve this goal if they are persistent enough in their inquiry.

It's midnight in the end of day -  from Wednesday to Thursday. As to why it was chosen, it's inspired by MPEx IDIFF futures that expire in same time (and they were in past actually used as backing). Having it in middle of workweek and not near beginning/end of month is convenient, too.

No offense taken

Certain party provided 80BTC collateral to CoinBr and obtained 2000 shares of CB.IDIFF-E in return . They then offered and sold shares for 0.022 (expecting the difficulty will end up lower than that). This week it happened again, but this time they are selling at 0.025 .

I recommend 24hour VWAP from http://www.bitcoincharts.com/markets/currencies/ . MPEx uses it for options exercises for over a year without problem (except when bitcoincharts is unreachable but that did not happen since April).

https://bitfunder.com/asset/CoinBr.iDiff-E August just paid out 0.00508103 BTC per share and October issue will be introduced both on BF and BTC-TC. We have to think at least twice about the parameters, with current ~2% daily hashrate growth

Please vote for https://btct.co/security/CB.IDIFF-E .

Update Aug 24: CB.IDIFF-E was successfully approved and is offered at 0.029 at the moment(pricing equivalent to future difficulty of 290 million).
It will expire at 16th October and difficulty limit is 400million, means max payout is 0.04 BTC per share. Thanks for all the votes!

Hello, we invite everyone around to first Satoshi Square person-to-person bitcoin exchange in Bratislava:

http://satoshi.sk/square

Place: Námestie SNP, Bratislava
Time: 30.8. 2013 @ 17:00
Bring some stuff to sell incl. your favourite national currency
Bring Bitcoins to sell
Bitcoin not Bombs t-shirt will be available

Very interesting. But biggest problem of bitcoin exchanges has been security, and the statement "it's programmed in PHP" does not instill confidence in this area. Was the system built or at least reviewed by known expert, with quality penetration tests? For example, in Slovakia http://digmia.com/ offers such services, and it's led by bitcoin enthusiast.

EDIT: I see Markus Weiler fits this role, misread it at first. And a question: How it is different or improved from bitcoin.de?

Our 89 offer for CoinBr.iDiff-O sold as well. We are not willing to risk more, so unless situation improves (difficulty stalls) there will be no more offers from us.  However, to prevent the asset trading way above maximal payout, we erected ask wall at 0.00999, which is obviously not meant to be bought into.

Yes, any difficulty increase above 100 million will pay maximum 0.01 BTC/share and no more.

First two questions - yes, correct.

The last question cannot be answered without more precise formulation what is exactly your goal. If your goal is to keep the profit fully at 0.20 BTC per GH/s in next 6 months even if difficulty increases by 30% every time or more (as per your table), you need the future to earn you 0.2 * 500 = 100 BTC. You can earn this from the difference between current sell price ~ 0.008 and maximum 0.01 per share  = 0.002 . This means you need  100/0.002 = 50000 shares of CB.IDIFF-O... but sadly, there isn't such a depth. Maybe in future when it will get established and backed by bigger investor than us.

Also, you can wait for introduction of CB.IDIFF-E October in ~ 2 weeks, which might better suit you time-wise.

We offer the same futures on Bitfunder since February and they were always paid out on time (regardless if at loss - already happened), as well as customers of CoinBr.com MPEx brokerage got all their withdrawals. CoinBr users were also among first ones when SatoshiDICE paid out, mind you that such an unexpected big event would cause any naked scam to fold.

And thanks davos for the explanation, you are correct.

Yes you're right. But estimate for next week says around 46 million, so it's not such a stretch from then on if various asic vendors keep shipping at current rate.  In fact, until today our sell price on Bitfunder was 0.0075 (and previously 0.0069), and we increased it there as well.

That only happens when people don't check the result in other (not logged in) browser. Preview function would help, too.

CoinBr will do the marketmaking itself up to our own reserves. The ask (at 0.006) and bid (at 0.0079) has been just placed Still, everyone is welcome to provide collateral and bid lower.

If you look on existing equivalent Bitfunder asset: https://bitfunder.com/asset/CoinBr.iDiff-O you see it's priced at 0.075, this means if you buy it you will profit only if difficulty will be higher than 75 million. All shares will be then destroyed, and for next cycle(November) there will be again higher prices offered.

The funds are used mostly as CoinBr operational capital and for conservative investment.

No corresponding BTC-TC assets exist, I'm not sure what do you mean. Only corresponding asset at the moment is https://bitfunder.com/asset/CoinBr.iDiff-O because it has same functionality and parameters, so only exchanging to and from it will be possible.

First future on BTC-TC introduced: https://btct.co/security/CB.IDIFF-O 

After successfully running mining difficulty futures on Bitfunder since February, we decided to offer the same mining futures on BTC-TC as well. It starts with CB.IDIFF-O September, which is now open for voting. CB.IDIFF-E October will be introduced later. They are completely equivalent to our CoinBr.iDiff-* assets on BitFunder and roughly comparable to X.IDIFF.* assets on MPEx.

EDIT August 5: CB.IDIFF.O is now trading, bids/asks up. I made a mistake in news announcement on BTC-TC,  please disregard the first version (hopefully burnside will remove it quickly).

CB.IDIFF-* futures are suitable for hedging mining operations/securities (for example, against new technology) and other kinds of short-term insurance/speculation against hashrate/mining difficulty. The share value at expiration is directly determined by current difficulty - as difficulty in satoshis/100.  In the asset details there is an example with concrete numbers.

This asset is available for shorting to anyone who provides collateral (example in asset details). Please inquiry on info@coinbr.com about doing so. Escrow at trusted third party is possible.

Thanks, but you could have announced it earlier in advance, and provide option to redeem underlying shares directly to mpex/coinbr users and get better price - now just 3 days after, the price hovers between 0.00082-83. I first offered you this solution and assistance when moving from GLBSE, you seem not to put any thought to it again
