I've looked at one but may want to make a tool that feeds the data in to my mobile and would be great to even see someone else already API'ed or at least see some options.

BTC/USD at Mt . Gox then converted using GBP/USD from (? source).

1443  Other / Beginners & Help / Re: Too many characters? on: March 26, 2013, 11:48:47 AM
This may have a really simple answer but why if the first 8 characters of the btc address are all unique do they need the other ones.  Huh

The first 8 characters are not "all unique", they just happen to be "unique enough" that it is extremely unlikely to ever have a collision.

Now Firstbits are different as they can be tied to a Bitcoin address because of the order they have been seen in the blockchain.   For instance, the Firstbits "1" will uniquely identify the first Bitcoin address that starts with a 1 -- which happen to be the Bitcoin address for the generated coin in the genesis block.  Every other Bitcoin address also starts with a 1, except the fist one in block 0 is the only one with a Firstbits of "1".

I've just noticed that has been suspended. Any insight?

The account possibly was compromised and used for spamming:

We also may suspend accounts for investigation if we suspect an account has been hacked or compromised.

Your domain is newly registered and has privacy protection enabled.

Your forum account is new.

You have not shown any trust history in the -otc Web of Trust.

And you hold (escrow) user's funds.

The history of sites run anonymously is not very good.  Even those that build up trust by being honest seem to eventually succumb to the allure of anonymous digital cash just sitting there for the taking.

If this is a gift-based crowdfunding (like Kickstarter) then it can be offered legally and there is no reasonable excuse not to disclose who the operator(s) are.

That still doesn't protect against against a claim of "oops, the site got hacked, coins are gone" or the operator simply disappearing.

In the instance where the person listing a project is soliciting funds, if things go wrong, that person may feel personally responsible for using a service that didn't have protections against a loss like I describe.

What assurance does this person have that any funds raised are secure (other than a claim of innocent intent)?
1446  Other / Beginners & Help / Re: Imagine this.. on: March 25, 2013, 11:20:31 AM
Bill Gates buys all the Bitcoin, sells it to the government, taxes everyone, we lose.

Bill Gates would run out of cash pretty quickly as the exchange rate would rise significantly.

But let's say for whatever reason he happened to have been able to buy all 10,948,725 BTC that have been issued today.  But in the next 24 hours there will still be 3,600 BTC issued (144 blocks, 25 BTC per block).  Then each bitcoin hold 100,000,000 Satoshis.

So each day there are 3,600,000,000 new Satoshis added to the bitcoin monetary base.  In two days there are enough Satoshis so that every man, woman and child on the planet could get one and there would be some Satoshis left over.

About the worst outcome from that is the government starts selling these coins and that introduces volatility, but then they would no longer have "all the bitcoins", so that defeats the point you were trying to make, I think.

2013-03-24: Cyprus Goes Cashless The Hard Way
1448  Other / Beginners & Help / Re: Any bitcoin brokers here or out there? on: March 25, 2013, 10:38:16 AM
I am thinking of starting a brokering business, introducing Bitcoin buyers and sellers, and providing a safe escrow service for the transaction. This allows people to trade without affecting the price out of their favour on the exchanges.

I only know a little of this, but what I'm learning is that finding the bulk sellers is harder than finding the bulk buyers,  The larger sellers might have coins from revenues arriving over a period of time (either mining or from sales to customers who pay using bitcoins).  This is in contrast to the bulk buyer who arrives and wants to purchase the full amount in a single transaction with little delay, and at a level somewhat close to the current spot rate.

So in order to have access to the seller's supply there needs to be capital so that the seller will never be turned away whether or not a buyer is already lined up for those coins.  The unsold stock may get converted to USDs and parked at an exchange until a buyer arrives, so as to protect against exchange rate risk, but that still is a capital intensive operation.

1449  Bitcoin / Legal / Re: FinCen and MtGox on: March 25, 2013, 09:01:06 AM
Doesn't MtGox have a US company that's registered with FinCen and handles all the exchanges? If so, US buyers/sellers through MtGox shouldn't be regulated, even in accordance with their new regulations. Thoughts?

If you are referring to Mutum Sigillum LLC, that is only used for Dwolla USD transactions to and from Mt. Gox.  I don't know that Mutum Sigillum is registered with FinCEN as an MSB.  

I believe this will soon be a moot point as accounts in the U.S. get transitioned over to service by Coinlab.  Coinlab has registered as an MSB, apparently with some reference to being a "seller of prepaid access".

1452  Economy / Economics / Re: With daily price variations of order of $10, how can you price anything in BTC? on: March 25, 2013, 07:36:00 AM
So why buy anything at all with BTC? Better wait, but then wait until when?

Similar reasoning can be applied if you are just to buy BTC and price is $10 more in the morning than it was in the evening. Indirectly you can spend $100 more on the same item. In one day! Again, why buy anything at all then?

The only reasonable behavior is then to just accumulate BTCs

It may depend on how easy it is for you to replenish your wallet so that your spending isn't causing you to deplete your Bitcoin balance.

In the U.S. I can transfer in funds cheaply from my bank using Dwolla. The cost is just $0.25 per transaction.

So I'll have USD funds at an exchange and as I make purchases with bitcoins I'll make a corresponding buy at my exchange so that my net BTC position doesn't decrease.

Additionally, there are people who receive bitcoins as income or wish to convert the increased purchasing power that the rising exchange rate has provided.   For them, there are costs and delays to convert that income to fiat.  If they can use those funds to pay for their purchases then they don't need to go through the hassle of cashing out.

So not everyone is hesitant to spend their coins.

Ideally though, external hardware should not be necessary to play our games! We've tested our site on a handful of tablets and phones, and it does seems to work well - but we haven't tested every device. I wonder what device you are using, and do you see the same problem of "clicks registering as scrolls" on other websites as well?

Have you tested in a bar with slightly intoxicated people? 

I have ... as I umm, was performing market research.  Or something.  For science, of course.

Women who happen to have long fingernails were the ones who seemed to have the hardest time with it.

Did you get any takers yet? If not I'll do it.

Someone has responded and is filling this transaction.  The payment (of 1,500Rs) was made and the next step is for Milaap to send the gift card via e-mail, so that's where this transaction is at for the moment.
1455  Bitcoin / Bitcoin Discussion / Re: Instant confirmation using only the blockchain. on: March 25, 2013, 04:48:42 AM
To be clear, I'm not trying to get around the small fees, only envisioning the speeding up of the process for the vendor and patron on a single transaction from a single wallet.

A credit card authorization ensures that the customer's credit account is open, is in good standing, and has sufficient funds to complete the submitted transaction.  If the card passes these checks, the issuing bank will place a hold on the funds for the amount of the authorization.

When looking at your credit card statement online you might see these transactions as being marked "pending" or "authorization hold".

Unless the transaction was "authorization only" (e.g., in the rental car scenario) the "pending" transaction is at some part of the several-day process for transferring funds from the customer's charge account to the merchant's bank account.  This is known as settlement.

Bitcoin doesn't have this same process flow however.  You could approximate the 0/unconfirmed being the "authorization" request and a transaction reaching six confirmations as being similar to "settlement", but these cannot be used interchangeably.

When the credit card authorization is made, the card issuer has the "master node" which is the authority as far as the customer's balance goes.

With Bitcoin there is no master node.  There is no single authority.  

So the double spending risk with Bitcoin has to do with the chance of getting a false positive when accepting a payment transaction that has no confirmations.  With no "master node" available, a merchant checks against the most recent copy of the blockchain to determine that the coins used to spend haven't already been spent.  

That would work, except that a dishonest person can cause the merchant to believe the transaction is valid while at the same time (or later time even) that dishonest party can then broadcast a different transaction that ends up spending the same funds a second time.

The use of 0/unconfirmed allows false positives (i.e., a Bitcoin client might show that funds were received when at a later time a block may arrive with conflicting information) and the initial 0/unconfirmed transaction will disappear as if it had never been made.

Because there's no way to see what is in future blocks then until those future blocks are mined a merchant is exposed to risk of a double spend.

There are various double spend attacks, but to a retail merchant the race attack is the primary one to be concerned with.  A merchant may use a payment processor (such as BitPay) or may go the do-it-yourself (DIY) route.  The client can be configured to protect against being super-vulnerable to the race-attack by not enabling incoming connections and to have outgoing connections be made to well-connected nodes.   There are additional protections that could possibly be built to assist merchants however so few merchants accept on 0/unconfirmed today there hasn't been strong calls for these protections.

For instance, a 0/unconfirmed from someone paying with recently received coins that too haven't yet confirmed is more risky than is a 0/unconfirmed payment from someone who paid using coins that already have had more than six confirmations.  Or another example is a payment made that ends up being low priority due to its size or having no fee paid, etc.   The merchant can tell right away that the transaction will not confirm quickly and might want to delay crediting the payment as the longer the transaction stays unconfirmed the less cost there is to an attacker using rogue mining nodes who will process double spend transactions for a fee.

A bricks and mortar merchant like Cups and Cakes in San Francisco doesn't have much exposure to a double spend attack because it is economically unprofitable.  Let's say a race attack against them succeeds one out of twenty times (probably even a conservative estimate, the more likely rate could be one out of fifty or worse even).  So that means the dishonest customer is visiting 19 times in order to get the 20th cupcake order for "free".  Cups and Cakes probably earns more than 5% profit on each sale, so even with this double-spend exposure they are not losing money due to an occasional double spend.

Using a tablet (or worse, mobile) the touch is sensitive -- and oftentimes instead of registering as a click [Edit: I think "touch" is the Andrid equivalent for click] the Android event is interpreted as a scoll operation [Edit: or a drag operation maybe?].

If there were some extenal device which has a single button, "click" for spinning the slots, that would be a useful device.

Does connecting up a gamepad to a tablet (e.g., Nexus 7) enable the ability for someone to bypass the touch and instead treat the button presses as keystroke entries (specifically, whatever is needed for the Spin operation?)

1457  Other / Beginners & Help / Re: MtGox CAD to "Real CAD" on: March 23, 2013, 08:17:15 PM
I've been looking around for a while on the internet, and I couldn't find a place to exchange my MtGox CAD redeem code for "real CAD". The recommended exchange, Aurumxchange, didn't have CAD. Has anybody had similar problems/solutions?

I can't remember if MTG CAD goes away when Coinlab takes over for U.S. and Canadian users of Mt. Gox (or April 10th, technically).  I know issuance of MTG USD is being ended.

Maybe you can find someone to trade them with on #bitcoin-cad IRC.
1458  Economy / Service Announcements / Re: Purchase Gift Cards for Merchants in USA BTC+Dwolla+Lyoness=Gift CARDS on: March 23, 2013, 08:00:22 PM
Comments please good or bad idea?

I've done this transaction (sold bitcoins, withdrew Dwolla and used the funds to buy a gift card through, and it worked fantastically.

The shipping and handling (S&H) for the card(s) is a $5 per order unless purchasing $300 or more of gift cards in which case the S&H is waived.

The order is sent FedEx.

So this is a 1:1 cash-out method.  You send $300 Dwolla USD you get $300 worth of gift cards in the mail.  The only cost in that instance is the $0.25 Dwolla per-transaction fee*.

In the U.S., the Gift Cards (physical cards mailed to you) available are:

 - Chevron
 - Exxon
 - BP (British Petroleum)
 - CVS Pharmacy
 - WalMart
 - Home Depot
 - Lowes
 - Sears
 - Footlocker
 - American Airlines
 - Outback Steakhouse
 - Rotelli Pizza and Pasta

[Edit: New brands include:
 - California Pizza Kitchen
 - Peet's Coffee & Tea
 - Priceline
 - Southwest Airlines Vacations
 - Sears
 - KMart
 - Dollar General
 - Linen's N Things
 - Guitar Center
 - New Balance
 - Golfsmith
 - Zumba fitness
 - Best Buy
 - Straight Talk Wireless (11%!!) ]

Additionally, with Dwolla funds sent to your account you can purchase "mobile gift cards" to certain local merchants.      So even if the merchant has no idea what Bitcoin is, there is a path from Bitcoin to these local merchants.

The reason Lyoness offers this is that it is part of its merchant loyalty program which offers cash-back credited to its members.   So this can actually provide a better than 1:1 cash-out method for Bitcoin since with the "cash back reward" you get more than $1 purchase power when including the cash-back reward received for purchases.

But remember, because this is using Dwolla to fund you can cash out at an exchange that uses Dwolla and this method does not require any withdrawal to a bank account.

Anyone in the U.S. can sign up for Dwolla.  You do not need to link a bank account to Dwolla to use this.

In addition to this being a method to use Dwolla funds to buy gift cards to national brands or to fund mobile gift cards to other merchants, there are cash-back benefits available at other merchants as well if you happen to be interested as well.  

Full disclosure, forum user EndTheFed321 gets a residual commission for all subsequent purchases made through by any members who are signed up by him.   That same ability to earn residuals is available to anyone else as well.

* If you don't already have a Dwolla account, you can sign up (referral link) and get a credit towards $10 of your Dwolla fees.

There will be at least two Bitcoiners meeting (myself being one of them) in Cerritos this afternoon (Saturday March 23, 2013).

Details for the afternoon event:

a meetup for Saturday March 23

place 11305 183 Street
90703 Cerritos

time 3:00 pm

[Update: There had been the desire expressed for an evening event as well. Notice was too short to try to plan one for today (Saturday March 23) but suggestions for an April date and location might help cause that to happen.  A location with Wi-Fi would be preferred.
