I wanted some community input on this just for fun:

I'm at a point where I have a 1/2oz silver coin die done that says 5 BITCOINS.  But 5 BTC is now worth a hell of a lot more than it was when I started.

I almost want to start over and do 1oz=1BTC 1/2oz=1/2BTC and a smaller coin for 0.1 BTC... all in silver, and offer each (at least the biggest one or two) with the optional gold plated B like I did last time.

Do I run some coins with the 5 BITCOINS die, or just scrap it?  It will seem kind of weird having a 5 and a 0.5 BTC coin that are, well, alike in every way, including the year 2013, and I'm tempted to just scrap the die.

A precious metal coin to me is strange when the face value is BTC, and pot metal could do just as good a job (instead of value = BTC + Silver + gold leaf - cost of separating Au & Ag + min(current premium, original premium). 1 oz = $27 of silver; If BTC drops 90% you could have coins worth more in metal than BTC. If you think silver is best to make them hard to counterfeit while easy to authenticate...

One Bitcoin is even a crazy coin now if the price doesn't pop, they've gone from USD $10 to $2 to $265 (now $234), it could be a new top-coin with the gold/silver design - for the same or lower BTC price premium as past 1BTC; a 1BTC looking as sharp as your avatar would be awesome just for the press picture.

Someone bought the $7000/1000BTC gold bar though, so there might still be a (fraudulent only?) market for a 5 BTC ~$1250 value.

I just updated to the latest Android app. Transaction fees are still defaulting to 0.005 BTC, which is really steep these days. I looked around and can't find a way to decrease this. Any ideas?

Thanks again for the great service!
Sounds like either the developer made a decimal place error, or they thought that mobile users needed fast confirmations, which a big fee will do - you don't want to wait for hours in some sketchy place if selling bitcoins.

Chinese are setting the standard yet again. Americans == babby tier traders

No fair, thats not really a good comparison .. Asians have gambling in their DNA!  
lolz

Rest assured Americans, your money is safe in your banks and unlikely to get lost anytime, until we decide to buy them with our bitcoins. Wink

Rest assured Chinese, your US dollars are safely in your banks where they can be inflated into worthlessness when we turn on the printing presses.
1293  Bitcoin / Development & Technical Discussion / Re: Significant slimming of Blockchain on: April 10, 2013, 07:21:50 AM
Trouble of blockchain size is often belittled, but I personally mind. Imagine 100 millions of people using bitcoin. Every day.
My proposal involves big changes in blockchain and I don't know how to impacts to security.
Namely.
In https://en.bitcoin.it/wiki/Introduction is Bitcoin idea:

   
Quote from: Bitcoin wiki
Suppose Alice wants to send a Bitcoin to Bob.
    1) Bob sends his address (from which the public key can be derived) to Alice.
    2) Alice adds Bob’s public key and the amount of bitcoins to transfer to a message: a 'transaction' message.
    3) Alice signs the transaction with her private key.
    4) Alice broadcasts the transaction on the Bitcoin network for all to see.

Step 4) causes big net traffic and disk usage.
How avoid it?
If we avoid it - Alice can send coin, but how prevent double-spending?
Bob can send money to Charlie because Charlie can know about transaction A->B from B.
Alice can send the same money to Charlie?
In Bitcoin net - No, because Charlie know transaction A->B
My idea is : Charlie and thousands users not know about A->B transaction while not need it
If Charlie need it, can ask B, how will he know that B?
- it is can be maybe like DHT system in BitTorrent and Kademlia (I know a not enough the details)
[correction!] What if Bob will not be logged? Alice (or maybe better Bob?) broadcast the transaction
to only a few users, the larger the network, the smaller the percentage of users.
if even Bob is not logged, the probability that is at least one user who know about transaction is near 1.
Even if probability is only 90%, Alice not risk double-spending because danger of ban (or even loss of coins? preferably no..)

Users will have smaller disk occupied, problem is bigger wallet - if anyone have one account and thousands of
donation, in Bitcoins secure wallet has only key to this account, here must be private transaction history,
but [correction!] if anyone else know this transactions, is possible to download it like download blocks,
at least theoretically.

Your idea is not new, the concept of thin clients is older than Bitcoin, except previous publications have been written from an informed perspective understanding how the blockchain and mining works to prevent double-spends.

Your last paragraph is to clever to be understood.

i was 14,250 in gox queue on Saturday, now i'm 11,800

one day later and i'm only 11,620 Sad

Now i'm 10,360 so i've moved nearly 4k places while the queue has still gone up over 4k, so i guess that means about 8k new requests since Saturday?
How many of those are signing up to cash out? 10% maybe?
Maybe more, you only find out you need to be verified (again) when you want to get your USD out.
1295  Bitcoin / Development & Technical Discussion / Re: Cancelling unconfirmed transactions on: April 10, 2013, 03:25:41 AM
One should determine between unconfirmed transaction and unbroadcasted transaction (what blablahblah was trying to say). Both look similar in the transaction list of Bitcoin client. But first has information in the chain already and latter doesn't.

It is up to client implementation. Satoshi client allows unbroadcasted transactions in it's internal pool (and by the way takes long time before attempt to re-broadcast it again). Other clients just don't even hold such transaction. They either broadcast them successfully or reject.

So unconfirmed transaction are not to be taken out of the chain. But unbroadcasted transaction are removable from the client queue (though with some third party software, Satoshi client doesn't have such functionality out of the box).
There is no "unbroadcasted" transaction, except when you haven't press the send button yet. However a transaction that does not include at least the minimum relay fee (currently 0.0001 BTC/kB) will not be communicated through the network to others by 99% of the Bitcoin nodes or recognized by miners, making it's timely inclusion in the blockchain even less likely. A replacement transaction that does include the required fee will be the one that is used, because it is not considered a double-spend by everybody that ignored the first one.
1296  Bitcoin / Development & Technical Discussion / Re: Cancelling unconfirmed transactions on: April 10, 2013, 02:54:29 AM
Hi

As far as I am aware it is not possible to cancel unconfirmed transactions currently.  If the block limit is maintained, this will likely lead to a scenario where first transactions without fees will go through in calmer moments, then not at all anymore.  
I was now thinking of the following scenario: somebody tries to be a cheapass by not adding a fee to his transaction, transaction volume picks up forever, and the transaction is stuck in limbo forever.  He might try a new doublespend with fee, but apparently that is not trivial either?  
Would it be good to implement a "cancel unconfirmed transaction" option in the clients?  Or does this already exist and is my information outdated?

I just did that same thing, because Im an idiot. I'm using blockchain.info's online wallet, but I can get the private key and run it off the bitcoin client locally. Can someone explain to me what would stop me from "double spending" the coins that are stuck in limbo, and would it actually be "double spending"?
If the transaction was sent with no fee when a minimum was required, the rebroadcast one with adequate fees (something more than the minimum) will probably go right through. There is no guarantee that it will use the same input payments and actually double-spend, unless you have a very minimal receiving history or send your entire balance. Note that this will make your Bitcoin-qt wallet your new wallet, as it will be the only one that has the change transaction, Bitcoin contains multiple addresses and doesn't reuse them.

I don't think they are very valuable. I have 34 of them in a wallet just sitting there
Send them to me then. http://explorer.dot-bit.org/n/74491

Last price before https://exchange.bitparking.com went down:

Namecoins also are now trading at .008 BTC, or ~$0.80, which is a 100% price spike above the previous months, and certainly higher in government currency than they have ever been. Alternate currencies may be seen by some investors as having more upward potential than already-recognized Bitcoin.

If you want to send your coins off to Russia, they are currently at 0.006 BTC

This was proposed many times
This was refused many times too


Ugh. Do you know why it was refused?
It is a non-issue if you just use Bitcoin and don't look at third-party websites that show you more information (and less information) than you need. The inner workings of transactions and change are transparent to Bitcoin users, just enter amount and press send.

If this was an elevator forum, people would be posting questions about how the elevator remembers which buttons have been pressed, how it stops at exactly the right spot, what the tension strength of the cables is, be proposing better algorithms to manage elevator traffic, discuss what music is best in the elevator, and post theories about how the failsafe brakes couldn't possibly work. Every week.
