2> The CME futures are financially settled, as opposed to physically settled.  While not confirmed, this will be based on an index of real exchanges such as GDAX.  But, this only matters for contract expiration.  (The daily settle will be based solely on the price of the futs themselves, not on external real exchanges such as GDAX.)


Settled against Gemini.

From CBOE website: http://cfe.cboe.com/cfe-products/xbt-cboe-bitcoin-futures?utm_campaign=bitcoin-futures&utm_medium=vanity-url&utm_source=na

"XBT futures are cash-settled contracts based on the Gemini's auction price for bitcoin, denominated in U.S. dollars."

This is likely responsible for recent GBTC correction. https://seekingalpha.com/article/4130800-bitcoin-investment-trust-set-big-correction

I can offer 26.26BTC and you ship it overnight. We use Dabs as escrow.

I offer 26.33 and can pay escrow.

Thanks guys - sorry but i like the coin too much, i would not part with it for that.

Can we see the other side please.





5  Economy / Collectibles / [WTS] Casascius 25 BTC on: March 20, 2017, 09:30:06 PM

Hi All - What is the market rate for a Casascius 25BTC? Ungraded, but condition is excellent. Original owner. Can't be too many of these about.

Likely to unseal within 24hrs unless I have a compelling reason not to - which I appreciate makes me a terrible human being.

You would need to be in London, England.

Let me know if there is any interest, though to set expectations I'd prob be looking for something over 28 to part with it.

In general the popular price trackers do a lot right, red/green flashes on price data changes, mini-charts, hyperlinks to more info etc. I like http://coincap.io/

Recs:

1. Add market caps. They are useful for at a glance guaging of unfamiliar tokens.
2. It should be possible to see easily how prices are calculated. E.g. Which exchange(s) data you are using, how recent data is and and what if any formulas/weighting etc. For example it would be great if hovering the mouse over an icon displayed for example "Latest price from Bitstamp @ 21:47". Few sites do this and it bugs me.

You could also try some more novel stuff - like display latest trends in google search activity for each token, maybe even rank them accordingly and see if there are any price correlations. I'm not aware of a dashboard such as this but i'd use one if there was one. https://www.coingecko.com/en has some stats along these lines (they track dev activity and - wierdly - bing results).

Thank you all.

@Danny you've given me food for thought...
8  Bitcoin / Development & Technical Discussion / Crypto security question on: January 23, 2016, 02:21:20 PM
Hi - looking for a bit of tech help

Pre-conditions:

1. Alice has encrypted the text "red" with her private key, and stores the ciphertext on a public ledger.
2. Her public key is known.
3. Bob knows that Alice has stored a ciphertext corresponding with either "red" or "white" on the ledger.

My Question:

Using the public key, the ciphertext, and knowing the possible cleartext values, is it possible for Bob to determine the value which has been stored?

To put the question another way: If required could Alice prove that the cleartext value is "Red" without using her private key?
9  Economy / Computer hardware / WTS Assorted PC Cables (UK) on: March 06, 2015, 01:03:20 PM

Noticed someone looking to buy similar cables recently (in the US) and remembered I have a heap of old cables, most of which are unused.

Anyone interested? Make me an offer, will sell the lot for best offers over £25 by next Saturday morning (Mar 14th) - payment in BTC.

I have no idea what the stuff is worth so apologies if the price is too high, i figured £5 for postage, and £20 for the goods is the minimum that would get my ass down to the post office, otherwise i'll just keep them.

Will consider partial offers but remember the 'ass-to-post-office' threshold stands

11  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: Cryptsy Users - Withdraw Your PTS or Risk Losing It - Immediate Action Needed on: January 27, 2015, 01:34:23 PM

As far as I understand it (which is not very far) - there would be no point in simply withdrawing PTS now (after the Dec 14 snapshot) since Cryptsy would just send the old (worthless) PTS to a new external address, and worse might discard the original ownership address from which new PTS can be claimed.

^^Is this right?

If so, unless Cryptsy are prepared to undertake the migration on behalf of all users (which i doubt for the reasons in the OP) I will need to convince them to send me the address and private key, then load it into the new wallet client running the new blockchain fork.

12  Alternate cryptocurrencies / Service Discussion (Altcoins) / Re: Cryptsy Users - Withdraw Your PTS or Risk Losing It - Immediate Action Needed on: January 27, 2015, 11:46:21 AM

OK - that's me, old PTS sitting Cryptsy and no way to migrate.

I have a support ticket open, asking what my options are.  Presumably Cryptsy have no plans to manually effect the migration, so I'm guessing I will need to try to get an export of the Cryptsy address and private key.

Is the procedure for migrating from old PTS to new PTS documented anywhere?  Is it as simple as importing the old address into a new client (as suggested here https://bitsharestalk.org/index.php?topic=11877.0)?
13  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BitShares PTS Mandatory Upgrade & Snapshot Announcement on: January 27, 2015, 10:57:58 AM

...
You need to contact cryptsy support open a ticket and ask them to knwo for sure. As far as I know, and I could be wrong but... I do not believe they honored the switch. and they are on the old blockchain.. if cryptsy is interested in doing the leg work they can take their PTS private keys, and unlock their respective coins on the new blockchain PTS-Dpos. then they could give each of their users with a balance 570 coins for every PTS coin they have. since cryptsy doesnt have any Delegated Proof of Stake coins, they may be unwilling to implement the changes needed to their system to accomodate, same as they never have made the changes necessary to implement any cryptonote coins like XMR.

ok thanks - have done that - I have a feeling this is going to be a long process.  There must be a ton of others in the same boat, what a mess.

If I can get my address and private key exported, are there instructions anywhere on how to perform this migration manually?

Also - have other DAC shares been issued over the past 12 months to PTS holders, assuming so, is there a process for accessing/tracking these (presumably also reliant on access to original address)?
14  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] BitShares PTS Mandatory Upgrade & Snapshot Announcement on: January 27, 2015, 01:02:23 AM
Hi - sorry for the lack of awareness, I'm WAY out of the loop on PTS, would appreciate some help.

I have some PTS sitting on Cryptsy (bought maybe a year ago then forgot all about them), now i'm trying to figure out a few things:

It looks like PTS is now "new PTS" - Cryptsy still shows my original balance of what is presumably "old PTS"

How do I get the "new PTS"? Do I need to do anything?

Do I now automatically own other air-dropped DAC shares too?

If so, same question - how do I see them?

No - the link is fake (see the pop up overlay), it would take me to a fake site, where i would be asked to enter my login details to check my account, then my account would get cleaned out.

dammit man - have you never orchestrated an organised cyber-fraud scheme?

17  Bitcoin / Bitcoin Discussion / Long list of addresses and (private?) keys on: January 16, 2015, 11:54:33 PM
Can anyone explain what this is?

http://directory.io/1#5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreAbuatmU

Looks like someone has spent a lot of time generating addresses.

I checked about 5 of the addresses, weirdly one has been used in the past, possibly some kind of test (https://blockchain.info/address/1QAALUJNskZWEbvwKXoTteowgs9xGGeAZR)

No idea if the private keys are actual private keys.

19  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [PRE-ANN][GEMS]| SOCIAL MESSAGING APP OWNED BY THE USERS | Gems public sale | on: October 22, 2014, 04:39:57 AM
this is not an "ipo" first of all.  an "ipo" happens when stock equity is offered to the public, generally after it has been offered to investors, employees and founders. before that there may be a seed round, an A round, B, C, D, F, G and H rounds or series. Warrants, preferences, etc. 

I'm guessing this is sort of like a sale of services or goods with future delivery...

Good point. The reason why the "IPO" term stuck back in tha day was that it was used as a go-to metaphor to make the pre-sale process intuitive. Legally, the Gems pre-sale is no more an IPO than a smile is a sunny day.  Smiley

I get that stock is not being sold here.  It is because this is not an ipo that I'd like to understand the structure/ownership/etc of the organisation which will manage BAU operations.
20  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [PRE-ANN][GEMS]| SOCIAL MESSAGING APP OWNED BY THE USERS | Gems public sale | on: October 21, 2014, 07:50:16 PM
This will almost certainly come across as negative, it is not intended to be so, but this thread is sorely lacking in the kind of objective, matter of fact due diligence that should be part and parcel of any attempt to secure capital for a new business venture.  I've listed a number of questions below:

Assuming all off-chain operations will be managed through a company, what is the current or proposed legal entity structure, registered headquarters etc

Equity ownership (of the legal company): who will own what?

Tax and financial compliance: what is the strategy? How will revenue, profit and loss be accounted and in which jurisdictions?

What legal jurisdictions will you operate in and do you plan to comply with all local regulations?

Can you confirm how many people work in the company, what their roles are, and their credentials? (Please no arguments over whether it is reasonable to expect this info, it is your prerogative to withhold, but it would be nice to have).

The fact that messages themselves are managed through an entirely off chain architecture alarms me:
How is anonymity guaranteed?
How is encryption guaranteed?
What (if any) user information will be held by the company and how can you assure user data will be securely protected (e.g. against hacking OR a legal government demand to hand over data).

How will core dev (or for that matter, all residual company operations) be sustained once IPO and dev bounty funds are exhausted?

Please explain roughly the scale of incentive value being offered to users, for instance would typical levels of messaging activity (say 10 messages / day) combined with opt-in adverts yield reward Gems worth >$5 per week, or <$.000001 per week. Just a rough estimate.

How will you attract users who may not interested in the ethics of the platform, or the prospect of making money from their social media participation, and who are demonstrably prepared to accept targeted ads in return for access to a platform rich in features and existing social connections, even in the knowledge that their messages are accessible to various snooping agencies. Like it or not, these are the users of today.

I don't like Facebook much, but with it I can see who is online, I can message a group of connections, add people to existing chats, I can see who has read my messages, and when they were read, I can post multiple media formats and I get push notifications when things of relevance happen - those are probably the features useful to me.  Does/will Gems have these features? When it comes to mass adoption, it is ALL about user experience, and you need to be better than the best to stand a chance.

All that said, the value redistribution model is where I think the industry is headed, however even this does not guarantee long term viability for Gems, because fundamentally gems appears to be a centralised messaging app which just happens to reward users, a model any of today's biggest competitors could embrace at any point.

Have you considered developing a protocol for social messaging which bakes messaging, advertising, and reward distribution directly into the protocol? I understand you see the linkage with the bitcoin blockchain as a priority, but this also limits the capabilities you can offer.  Have you considered integration with other (or additional) blockchains better suited to the capabilities your core product requires (maidsafe, Storj, ethereum etc).
