Mother of god. Any other banks are doing the same?
Look at the bottom of the page:

Better start asking around to see if the banks you use have any upcoming changes to their international wire policy in the pipeline.

I'm confused by this thread. You guys understand that the payment protocol already allows the recipient to request an arbitrary number of outputs, right?
With an extended public key there is no need for the sender to request a pre-defined number of outputs at the negotiation phase. When a recipient gives a sender a BIP32 key that sender now has the ability to create as many as they will need, forever, with no need for additional negotiation.

Altcoin discussion belongs in the altcoin discussion area.
I am not talking about alt coins, I think this should belong in bitcoin. If there are less addresses to track, there should be less blockcahin size.
What you're talking about is not Bitcoin, and will never be accepted into Bitcoin.

If you want this, make a new cryptocurrency with the feature and see how many people you can convince to switch.

Well, if you've got a large amount, you can go to a different bank that does allow wires and move from there, right?
Sure, as long as such banks continue to exist.

I'm tempted to create a bet as to whether or not any banks will offer individuals the ability to send funds out of the US via international six months from now.
3326  Economy / Speculation / Re: Bitcoin might rise over 200 unexpectedly soon on: October 17, 2013, 04:37:44 AM
The main message of that dream was not 200+ prices but the fact that 150 .. 200 range will be conquered surprisingly fast. One might wonder what is the time period for surprisingly fast. My wild guess was a month but it can be longer as the dream didn't say anything about exact dates - just the fact that it would happen quickly.
Do you know what would be the exact opposite of surprising?

If the space between $158.49 and $199.53 took between 30.3 and 34.5 days to cross.

It wouldn't be surprising because based on price history to date*, that's how much time it takes on average to span a tenth of a decade.



*past results are no guarantee of future performance.

You can always use WU/moneygram, can you not?
Western Union is very expensive compared to wires, and comes with far lower limits on the amount you can transfer.

Bitcoin companies aren't run in a way which would give them much control over the community yet. In the future that could change if the community depends too much on Bitcoins and does not diversify into altcoins.
Any excuse, not matter how flimsy, to pump scamcoin will do, right?

An extended public key only lets you see the transactions in the subchain its on. Not all your transactions!
It's still an inexcusably-high amount of metadata to leak.

It's not terrible for privacy, its essential for privacy because the alternative is the addresses people put in their signatures/profiles which get automatically scraped and listed on the web.
The alternative is that the forum gives out some token that can be used to find the other person to exchange pubkeys directly, without the forum being able to record the information itself.

For example, your HD wallet client can have Torchat functionality built in, and you post the address in your profile such that anyone wanting to get payment information can point their client to that address.

Substitute Bitmessage, or any other eavesdropping-resistant P2P messaging system, for Torchat as desired.

It just takes a bit more thought to architect the negotiation protocol, but it's not all that complicated. For extra credit, you design the extended pubkey request and exchange protocol to be transport-independent and add a plugin feature to the clients such that you can do it over Torchat, Bitmessage, IRC, I2P, Freenet, or any protocol you can write a transport plugin for.

I track the trend differently - I keep a spreadsheet wherein I track the weekly weighted prices and calculate an average of all the changes.

So far that gives an average weekly change of 6.4%, including the data from all the way back to the first day Mt Gox opened.

Using that gives about $300 by the end of the year, with $1000 being reached slightly under a year from now.

Here's the same thing happening at a small, state-licenced bank:

Foreign Wire Transfers: Due to recent regulatory changes, effective 10/1/13, FNBT/FCB will no longer offer foreign wire transfer services through Internet Banking or in banking centers.

If you need to send funds to a recipient in a foreign country, you can go to www.westernunion.com to send a transfer using your Debit MasterCard® or visit your local banking center to send a Western Union in person.
The key here is "Due to recent regulatory changes." This isn't a Chase issue. I bet that we're going to hear more of this happening in the next few days/weeks. Before long, it's not going to be possible for the average person to wire dollars outside the country.

If you're serious the best place to get $30 worth of bitcoins is LocalBitcoins. Just find somebody in your area and pay cash.

Newbies who ask to pay with PayPal are generally suspected of being scammers.

3335  Bitcoin / Development & Technical Discussion / HD wallets for increased transaction privacy [split from CoinJoin thread] on: October 16, 2013, 11:42:44 PM
I had assumed what @justusranvier described was/will be the convention for HD wallet applications.
Specifically, for cases such as an employer paying employees. BIP32 solves this problem nicely.

The only reliable solution is to source your coins in small values, so you don't need to split value. Yet this is not possible if the payer is splitting and paying you numerous times, e.g. an employer.

This is actually an interesting problem, that is difficult to solve with current bitcoin.

Entities that issue regular payouts -- in my case, ASICMINER, Eligius and my employer BitPay -- inevitably set up a single payout address, and then send multiple payments to that address.

This is certainly sub-optimal, and reduces privacy.  No amount of CoinJoin'ing by itself will fix this multiple-payout/single-address problem.  We'll call it "recurring incoming payments."

Recurring incoming payments -- and recurring outgoing payments (subscriptions) -- are problems that bitcoin is quite unsuited to address right now.

To increase privacy, those who pay out need some standardized way to request multiple addresses from their payees.
Also, I think AnonyMint had it backwards. Splitting outputs is fine; there are plenty of ways do it safely. Recombining small balances into large balances without sacrificing privacy is the hard part, and that's where CoinJoin can help.

I am saying that FORUM USERS. Like you and I. Can provide the forum with an extended public key so that other forum users can requests addresses for us without making all of those addresses public.
Why would anyone want to give the forum operators the ability to track all their transactions? That's terrible for privacy. I'm never going to give someone an extended public key except for an entity I want to receive payments from.
3337  Economy / Economics / Re: Chase Bank limits withdrawls, Bans international wires on: October 16, 2013, 11:10:40 PM
I can't believe this is even legal, let alone something a solvent bank would consider doing.
I saw something similar happen at a local, state-licensed bank:

If you want to know what happens next, study the recent history of Argentina.

That's correct. It belongs in every section of the forum.
I feel like I should be able to refute that, but I don't want to.
3339  Bitcoin / Development & Technical Discussion / HD wallets for increased transaction privacy [split from CoinJoin thread] on: October 16, 2013, 09:57:28 PM
Right, but at a minimum we need well defined conventions.
The convention I would use is, "Here's an extended public key. I am going to watch the first address defined in this sequence for an incoming payment. After I see it, I'm going to start watching the second address. After I see a payment there I'm going to start watching the third address, etc."

I do wonder about things like griefing a forum donation forum. E.g. I give the forum an extended public key so it can give each donor a fresh address, and then some clown asks for 10000 addresses and never pays.  Writing advice to address this is part of having a good spec for the usage of extended public keys.
A client can do several things to limit the amount of addresses they need to scan.

First of all there's no reason for a forum to let a single person request 10000 extended public keys.

The forum has it's BIP32 seed and generates a subnode for each registered member.

Each member can go to their account and find the extended public key for them to donate with. They don't ever get a new one because the one they are assigned lets them generate all the deposit addresses they will ever need.

The forum's client has a small lookahead window, like 5 or 10. Whenever a new incoming payments are received the window increments accordingly.

Old addresses are checked for new balances at exponentially-increasing intervals until some cutoff time after which they are only checked manually.

It's awesome that you've got a new video out, even though the thread doesn't belong in this section of the forum.
