Can you post screenshots and blockexplorer links so we can get a better idea what's happening?

Change addresses aren't invisible. They're stored in the public blockchain - the change isn't yours until the network sees it, so it has to be this way.

The block you're signing contains the payout to the pool's wallet. If you change that to your private wallet your hash is no longer valid.

They likely just trade the escrowed coins to USD, then trade back to BTC for delivery when the buyer releases the funds.
They could also sell short on Bitcoinica, but selling the escrowed funds directly is probably cheaper and easier.

I suggest trying this list of online-only banks. I don't know if any meet your requirements, but it's a good starting point. http://www.pfstuff.com/I know it's hard to get an account as a nonresident. If you don't succeed, I can at least solve the problem of VEF devaluing against the USD: if you trust a Bitcoin exchange that supports USD, just keep your money as USD there, and trade to BTC when you want to spend. If you would prefer to work with a domestic (VE) institution, you can do the same with the forex markets: just deposit your VEF, trade to USD, and only trade back when you want to spend.

CampBX, because: - I prefer keeping my USD in the US;
- I want to support a small exchange because we badly need competition.
Previously I used ExchB for the same reasons.

fromaccount is an account, which is not the same as an address. Addresses are things that go in the blockchain. Accounts are just virtual ledgers within your wallet. The default client can't spend specific coins, but you can do it with the coderrr fork. Get it here: https://bitcointalk.org/index.php?topic=24784.0;all

Volatility is a problem because it adds an unneeded level of uncertainty and urgency to every transaction. Just IMO. AS for the rest, my signature is relevant. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

Closed source is a non-starter for p2p pool.
#3 doesn't belong in a code of ethics. Ethics are not about doing something for a reward. It's about simply doing what's right...
... Like not committing fraud, which is what I consider it to be when you reverse legitimate transactions with a 51% attack.

I have a copy of the depth for the last several months. It's not complete (I have some network outages), and I don't have a convenient web viewer, but I manually generate charts occasionally when interesting things happen: ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FOXJJm.png&t=663&c=FD2-JAkH1tV6fw) I consider these charts to be educational in how the market works, good for spotting abnormal trading behavior (as above), and useful when training bots, but not a very reliable way to trade. I'm happy to share the data if someone would like to make a better viewer.

Sorry, you'll have to speak up. I can't hear anything with all this bear fur in my ears. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

That's something that's worried me. How large of transaction fees will be required to ensure security? I think double-spends won't be a problem; it's too hard to exploit even against a fairly small network.
On the other hand, I am concerned that someone with a vested interest in killing Bitcoin - government, banks, whatever - will pull a luke-jr and DOS the network. We might have to throw a lot of money to miners to stop it.

Eligius itself won't mine your transaction but they WILL relay it. Eventually a zero-fee miner will pick it up.
This used to work when we had a decent number of solo miners. I don't know how it'll turn out in the current age of million+ difficulty.

You can resend the balance of that address to a new address. The new transaction will be confirmed and the old one dropped. Then you can send the coins from the new address. Unfortunately that's all theoretical. I'm not sure what software exists that would let you construct the double-spend.

That's clever. I like the idea. I would use it.

If GovCoin is decentralized like Bitcoin, what would they gain? They just end up with two coins they can't control instead of one.
If GovCoin is centralized, it's just an electronic version of fiat... It's your debit card, but run on the government's network instead of the bank's. That's kind of interesting, but it's not revolutionary.
