If Bitcoin rises in value vis-a-vis silver sufficiently, these premiums may be reduced downward.

The 0.05 BTC premium is now an amount worth more than $8.

305  Alternate cryptocurrencies / Altcoin Discussion / Re: What would happen if ASIC on Scrypt chain? on: October 14, 2013, 10:14:20 AM
What if the ASIC found the solution, and then passed that solution on to the video card so that the video card can generate that necessary proof of work?  In other words, couldn't they be made to work in tandem?

An ASIC does ONLY what the electronic paths in the silicon allow it to do.  SHA256 hashing is what the ASIC in an ASIC miner does.   If even one tiny little change to the computation is needed, that ASIC design is useless.   Scrypt is way different from SHA256.  There is no computation from any ASIC miner hardware that is even remotely useful in performing a Scrypt hash.
306  Bitcoin / Bitcoin Discussion / Re: Removing old coin uncertainty on: October 14, 2013, 09:59:44 AM
Every market thrives on information.  I would argue that large uncertainty about the amount of lost coins is hurting bitcoin adoption, especially its use as a store of value.

Is that really what your concern is?   Or is this the back-door you are looking at into allowing demurrage to get a foot in the door? (You wouldn't be the first).
307  Bitcoin / Mining / Re: How did BitCoin start on a technical prospective on: October 13, 2013, 10:57:22 PM
But how did it start? I mean back when noone had a bitcoin or a fraction of it.. how did the frist miners mine.. what was the "job" that was assigned to them? since there could not be a blockchain of transactions since no transaction occured at the very beginning of bitcoins...

Ya, the blockchain concept is a little foreign and takes a while to understand.

The "work" performed in mining is to compile a block that contains the coinbase transaction as well as ZERO or more additional transactions, and then perform a hash of the block such that the numeric value of the output of that hash is below some target "difficulty" value.

So there didn't need to be any additional transactions to build a block, other than the coinbase transaction.  Even today there are blocks mined occasionally with zero additional transactions in them (other than the coinbase transaction itself), simply because whoever mined it didn't include any.  That's perfectly valid, just not economically smart since there were likely fees from other transactions that were passed up.

Here's the first block

Click on Next block .... it goes until block 170 without any transactions:

308  Bitcoin / Bitcoin Discussion / Re: Bitcoin is way behind at mobile payments on: October 13, 2013, 06:33:33 PM
Why can't I do this with bitcoin?

Well, today using a third party service I can send Bitcoin to anyone else knowing just that person's mobile phone number or e-mail address (using Coinapult, or Coinbase), or that person's Twitter (using @BTCTip bot), or that person's Reddit username (using BitcoinTip bot), etc.

A problem exists with spoofing though.   I can write the message:

Quote
Seth is hosting an all-you-can-drink beer meetup for 0.1 BTC.  To join, send him payment at: 1PC9aZC4hNX2rmmrt7uHTfYAS3hRbph4UN

And the problem is, .... you did not make this offer, and ... that address isn't even your Bitcoin address.   With Simple's P2P system such fraudulent activity is reversible and thus there is less chance that the scammer will profit, so there is very little attempts at such type of fraud.    If those transfers of funds were non-reversible their P2P payments system would become a cesspool with spoofed profiles and fake offers, essentially rendering it unusable and giving a black eye to Simple.

Now with the payment protocol coming in Bitcoin-Qt/bitcoind v0.9, verifying such a request as being authentic will be easier.

Additionally, I am cautious about using an app without there being two-factor authentication.  But if my mobile is my 2FA device and the app needing the 2FA code is on the same mobile, then 2FA really isn't giving me much additional security.  Right now, my only remedy for such a problem is to only hold in that E-wallet app as much money as I'm willing to lose should my device become compromised.   (In a similar manner as how I don't generally carry more than a certain amount of cash in my physical wallet in my back pocket either.)

These probably aren't the reasons a Bitcoin-based equivalent to Simple's Money Drop isn't already available, just that improvements to security will help make it so that such an app can actually be built and be useful.
309  Bitcoin / Technical Support / Re: Bitcoin lost after 120 confirmations on: October 13, 2013, 04:55:16 AM
They never showed up in the recipient address..what gives?

Well, the confirmations provide proof that the funds were delivered to that Bitcoin address.  So if that E-Wallet hasn't given you credit you'll need to contact them to see why your account wasn't credited.
310  Bitcoin / Technical Support / Re: Bitcoin lost after 120 confirmations on: October 13, 2013, 02:56:49 AM
it also looksl ike it automatically sent it to the above address in the link below..but I never authorized that.

Just to make sure you aren't misunderstanding ... is this with a local client (such as Bitcoin-Qt/bitcoind, or is it with a hosted (shared) E-Wallet (such as an exchange account like you get with MT. Gox)?

With an E-Wallet, that service simply credits your account with any deposits made to that Bitcoin address.  But once that happens the blockchain can show those coins moving elsewhere but that won't affect your E-Wallet balance.

So to get a better answer to your question, please share more info, such as what client or service you are using.

312  Bitcoin / Bitcoin Discussion / Re: How to use fiat currencies for Bitcoin offline transactions? on: October 09, 2013, 11:04:03 PM
Finally, for the system to work, everyone must agree that those BTC bills really hold the BTC value.  But you can count on me:  I would agree! Why not?

Why not?   Because, the bitcoins cannot be spent electronically.    They then lose some their value.  At a minimum, these coins lose fungability.

Now what I could see happening is an "issuer" making these fiat into "colored notes" [Edit: in the same vein as how a bitcoin output can be dual-purposed to represent a share of an equity].  Each note can be redeemed for bitcoins, on demand.

So simply needed is some way to verify the XBT value of the note, using the note's serial number.  

This still requires that you trust the issuer, but if the issuer is honest there is little the government can do to confiscate funds from either the issuer or from the bearer except at the exchange points.
313  Alternate cryptocurrencies / Altcoin Discussion / Re: List of exchanges on: October 09, 2013, 10:31:22 PM
Can you tell me what XLT is?

Doh!   That's me not checking my work!

The ISO currency naming uses an X prefix for currencies that do not have a government issuer.  Thus gold (Au), is XAU.   It has been proposed to that ISO group to use XBT for Bitcoin.    I thought I had seen XLT at Kraken but I hadn't.   They are (properly) using LTC as the symbol yet.

Ah, so it looks like the OP could use an edit?

315  Economy / Speculation / Re: Which is LEADING: Bitstamp or Gox? on: October 09, 2013, 04:39:17 PM
Leading =/= being the closest to gox  Huh

Pardon me for being ignorant here, but maybe I'm not the only one.  In what context is "=/=" used?       If it was to mean "roughly equal" I'ld have expected to see (~=).   If it was "not equal" then I'ld expect "!=" or "<>".     But "=/=" isn't intuitive to me.

Which exchange sets the price that the other one  will catch up with?

You presume prices always equilibrate?   That will not always happen.  And it has little to do with trading volume.   Instead, various differences between exchanges are reflected in the price.    If there was zero friction between moving funds to and from exchanges, the prices would be the same.   As long as there are differences, the cost (or savings) of those differences are reflected in the exchange rate.

Now a spike or drop in volume (or urgency) may cause the degree of difference between the exchanges to grow or shrink over time but generally the exchange rate will move up or down at roughly the same level between the exchanges.

As far as determining a single "current market price" for bitcoin, currently Mt. Gox must be seen as an outlier but those bids are real so it cannot be entirely dismissed.   If you notice, both Coindesk's Bitcoin Price Indicator (BPI) and BItPay's exchange rate -- each computed with slightly different approaches yet seem to always land within about 1% of each other:

So Borja will be carrying the local currency in each country?  Or US dollars?  Or Huh

320  Bitcoin / Bitcoin Discussion / Re: Hardware device and protocol for seeding and verifying Provably Fair gaming on: October 08, 2013, 06:56:59 PM
In a very brief chat with someone familiar with casino operations I inquired about the potential that some day a player-owned device would be used to participate in "provably fair" gaming on physical gaming systems (e.g., video slots, video poker machines, etc.)    I was told that the use of mobile phones and other electronics were not permitted in certain areas of a casino.   The purpose of that was to prevent player cheating at table games and for restrictions related to the casino's sportsbook.

The most interesting part of the conversation was the assertion that players should not be worried about the casino cheating.  "Just trust us".  Heh, we've heard that before.
