It would sure be nice to have oil (WTI/Brent) as a tradeable product on one of these brokers...

ICBit had it at one time.

There were few contracts traded so after expiration no new contract issue was offered.   The spread was regularly pretty wide but due to volatility there were times when using that contract as a hedge against crude was affordable.

As long as Bitcoin distinguishes itself by allowing 2fa or some other wallet control, then it makes an ideal wallet for subscription based content.


There is some 2FA approach for use with P2SH as Gavin describes: https://gist.github.com/gavinandresen/5616606, but that's is likely way overkill to make it work with a micropayments subscription type of of application.   

Coinbase's subscriptions service probably could provide greater ease-of-use, and since it is already offered today by Coinbase that could be implemented more easily.   But the problem with Coinbase's subscriptions is that the customer is pre-authorizing the "merchant" to withdraw.  With the Open MediaWallet concept as I understand it, the content creators would each be merchants and thus that Coinbase subscription model doesn't work.  If there was a single Coinbase account for all MediaWallet content creators, about the only protection from abuse (e.g., payment drawn without approval by a scammer acting as content creator) comes from the amount being limited (i.e., $X per-week limit).

Rather than subscriptions, the micropayments channel (which  BitcoinJ has now implemented) would be a better fit:

383  Economy / Speculation / Re: Lets talk BTC price over the next few months (downward move imminent?) on: August 26, 2013, 08:39:41 PM
Why do so many people assume miners HAVE to sell bitcoins right away to "pay bills"?

Why not assume the have other resources and can horde?

That's likely due to the situation when mining was for GPUs and the Bitcoin revenues dropped to where they barely matched the increase in the electricity bill.    There was a high level of whinging (e.g., October and November 2011) by those who felt they "got suckered" into buying hardware (which is kind of true, since much press from May, June and July 2011 touted how miners were making huge bank.  These were not crypto-currency enthusiasts, they were techies who saw their friends getting "free hardware" and they jumped in -- oftentimes maxing out the credit card to do so.   So many of them truly were selling most every coin they mined and used the proceeds for paying off the purchase of the hardware and for the electric bill.  So then, of course, when difficulty rose it took more and more bitcoins, which collectively pushed the exchange rate lower ... incenting further spending, and spiraling on and on further down it went.

The miners who bought ASICs had to pay the cost up front so there's little additional cost to operating ASIC hardware yet (relative to BTCs earned), and thus more miners are today saving their coins than when comparing to 2011 when that sell-everything-you-earn behavior was prevalent.

Assuming you are worried about the write-off, I see two issues. BTC is more anonymous than the government would prefer.

Charities accept cash and Bitcoin should actually be more desirable as it is a payment method that offers a form of triple entry accounting.  Triple entry is the most transparent method for bookeeping that other ledger systems for charities should emulate!

it, but there isn't a way for you to get the peers to drop the transaction faster.

I suppose this conversation wouldn't be complete without mention of the "replace by fee" patch, which essentially allows double spending of an unconfirmed transaction.   While the replace by fee patch is real and exists today, there are few (if any) miners using it so the chances of successfully double spending to recover the funds for your own unconfirmed transaction are very low.

Initial replace-by-fee implementation is now available on testnet

391  Economy / Economics / Re: Gold to Bitcoin Ratio in dollars historical chart on: August 21, 2013, 04:30:32 PM
Does anyone know a website that tracks gold to bitcoin ration priced in dollars? Historical charts would be helpful.

One year chart.
 - http://bitcoinity.org/charts/gold
 

When I provided a monthly update I needed this data so I published the spreadsheet here:
 - https://docs.google.com/spreadsheet/ccc?key=0AmcTCtjBoRWUdHJuUE1mUkFxa3A0eHBDQkxZLVVFZmc#gid=0

With chart:
 - https://docs.google.com/spreadsheet/ccc?key=0AmcTCtjBoRWUdHJuUE1mUkFxa3A0eHBDQkxZLVVFZmc#gid=3

But I've not updated that in over half a year.

At the bottom it lists the data sources.  For gold:
 - http://www.ofdp.org/continuous_contracts/data?exchange=CEC&symbol=GC&depth=1

So the non-automated process of pulling the data from that involved copying from the HTML page then massaging it in a spreadsheet to get just the daily price data.
392  Bitcoin / Technical Support / Re: No Confirm Transactions on: August 21, 2013, 09:09:16 AM
Is it possible to send a transaction that will not confirm, but go back to your wallet quickly?

Each client handles transactions that won't confirm differently.  Bitcoin-Qt/bitcoind will continue to re-broadcast the transaction (sporadically, perhaps twice an hour) indefinitely.

Blockchain.info will restore the funds for a transaction that doesn't confirm after about a day.

Each of the other clients may have their own approach.

The behavior of your local client as far as letting you re-spend the funds is immaterial however if the original transaction is still hanging around in the memory pool of miners.   They might hold onto it for a full day or so even perhaps.

This is concerning.

The story is describing an investment in an online-only stock market that operates on the internet, under the radar of regulators.

These "stocks" traded probably could be named cyber-equities as they generally are for "assets" that are not necessarily legally-defined entities.  One of the "stocks" 796 offers (and the "IPO" that the story described) is for 796 itself (796Xchange-MRI).  

Any responsible reporting should caution the reader on the risks of such a market.

Either way, what is concerning is how the author of the article doesn't segregate the issues.  Bitcoin is like a commodity.  To date, no regulators have described Bitcoin as a security.    But these cyber-equities exchanges are not Bitcoin.   It's like describing how Germany's regulators described Bitcoin as being a legal private currency there and then extrapolating that into describing how that will legitimize purchases on Silk Road.  

Bitcoin and the ways it are used are completely different topics!

395  Bitcoin / Mining speculation / Re: Does anyone have estimates of the cost of a 51% attack at various times? on: August 21, 2013, 02:55:00 AM
Even if you had the money, nobody is producing enough equipment for you to buy it.

Exactly.  Unless the attacker created an ASIC or has had 50% of the orders in with the existing manufacturers there's simply no amount of money that will yield enough hardware to get 50% of the hashing capacity out there.   Perhaps a globally coordinated seizure of output from all the ASIC vendors might get the attacker that much hardware but then the chance of a "surprise" (necessary for executing a successful 51% for the purpose of double spending) drops to zero.
