If you need a financial partner to make similar services in euros and in Europe, let me know.  If you need investors to help you get some funds, let me know as well.

... Ask and ye shall receive. Send me an email. Smiley

Done.  Basically I'm just offering to provide euros and bitcoins in order to add EUR/BTC exchange to your website.
3602  Bitcoin / Development & Technical Discussion / Who uses the GUI anyway ? on: November 26, 2010, 12:17:23 AM
I don't use the GUI anymore.  I use only the headless client.

I think it would be much easier to integrate bitcoin in linux distributions if there was no gui.

And I think it would be good for bitcoin if it could be directly available through package repositories of main linux distributions.

Wouldn't it be great if debian users could just "apt-get install bitcoin" ?

Maybe you should PM satoshi about this.
3604  Bitcoin / Bitcoin Discussion / Re: BitcoinPromote.com - power in numbers on: November 25, 2010, 08:01:04 PM
I've created a new project called BitcoinPromote.com

The idea is simple.   It's an organized, ongoing, letter-writing campaign.

We continue to add organizations, charities, businesses, and other entities, to our Target List.

Gosh I'm way too lazy to do this kind of stuff...
3605  Bitcoin / Bitcoin Discussion / Re: Shopping Online - Now EVERY Store Accepts Bitcoin on: November 25, 2010, 07:36:20 PM
His service converts Bitcoin into a Visa credit card number... which you can use for shopping online anywhere.  Nothing whatsoever to do with PayPal or bank wire transfers.

Well, freewear.org 's paiement methods were Paypal or bank transfer.  So I had to create a Paypal account.

Still, Madhatter has done something great.  I can't deny it.
3606  Bitcoin / Development & Technical Discussion / Re: Bitcoins sub-nets on: November 25, 2010, 04:20:59 PM
I guess I'd like another requirement on this sub-net too:  It should be peer-to-peer and not a centralized solution.  Yes, a central server could perform this kind of system with all of the headaches and problems that such a solution also provides.  I would personally like to avoid having to turn Bitcoins into a conventional client-server model with a central authority which can be attacked.  It goes against the grain of why Bitcoins was originally established.

Bitcoins itself could be built into a central server system too, but I perceive the peer to peer nature of Bitcoins to be an essential strength of the system and something to be modeled onto sub-nets too.

I doubt a peer-to-peer system is appropriate if you have to make thousands of transactions per minute.   Because all transactions have to spread to the network.  This necessarly takes some time, and I'm not even talking about the process time (hashing of the blocks).

Therefore, cryptocurrencies have an intrinsic limit to the speed it can process transactions.

For very fast transaction, the account/centralised system can be used, as long as it is backed by bitcoins.
3607  Bitcoin / Development & Technical Discussion / Re: Bitcoins sub-nets on: November 25, 2010, 03:15:48 PM

If you really need huge number of micropaiements per client per day, I'd suggest you to use a different paiement system.

You could use an account-based paiement system.  Optionnaly this could use David Chaum's e-cash system if you want anonymity.

Anyway, your clients would have an account on your server, and they could change their balance into bitcoin when it reaches a significtive amount, or on a daily basis.
3608  Other / Off-topic / Re: Open Source Bank on: November 25, 2010, 03:08:53 PM
With bitcoin, everyone is his own bank.  Therefore I doubt the idea of an iternet open bank would be much different than the bitcoin system.

I finally managed to pay for my Vim and Debian T-shirts on freewear.org.

I had to create a paypal account though  Sad

But I very much prefer giving Paypal a virtual card, rather than my "hard" card number.

Seriously what you've done is great, Madhatter.  You might have a serious business model and financial activity, there.

In conjonction with your bitcoin4cash service, this just kicks ass !

Do you have any idea if this could be done in Europe, too ?


If you need a financial partner to make similar services in euros and in Europe, let me know.  If you need investors to help you get some funds, let me know as well.


Also, could you explain this ?  (it's from your FAQ)

    <<
    How do I check the balance of my card? / How do I activate the
    card? / How do I set the name/address on the card for online/telephone
    use?

    Due to the fact that we use more than one bank these details are revealed
    after your purchase has been made.
    >>

For instance I've just bought for about CAD$70 of T-shirts.  Now I should have about CAD$30 left on my balance.

I'd like to make sure of this in order to sell the remaining amount against bitcoins.

Edit.

OMG this is so cool !   I've managed to credit my shareholding account of EUR20 (a little less than CAD$30) directly using this.

This is great.  I guess now my balance is about EUR2.2.  What would happen if I try to transfer 10 ?  I guess the paiement would just be refused, right ?


Edit again.  Ok I get it !  I can check the balance here :  www.mybalance.ca

OMG this is really a great stuff !  Damned it Canada is quite a liberal country !!
3610  Economy / Marketplace / Re: Bitcoin2CC - Convert Bitcoins into a Virtual VISA Card Instantly! on: November 25, 2010, 09:55:39 AM

Just bought a $100  virtual card.   The process was quick and easy.


I'm looking forward to buy some stuffs with that.  I hope it will work fine.


Thanks again Madhatter !
3611  Bitcoin / Bitcoin Discussion / Re: Bad probabilistic news for small-time miners on: November 24, 2010, 09:30:22 PM
I guess that's what the distributed mining is all about - where you sign up your CPU to mine together with lots of other people.  Then the 50BTC reward for a block is shared by everyone.

Agreed.  I don't see many other solutions than this one.
3612  Bitcoin / Bitcoin Discussion / Re: Bad probabilistic news for small-time miners on: November 24, 2010, 09:21:58 PM
There must be an incentive for small miners to hash.  At the rate we are going only the top miners will continue to mine and it is possible there could only be one left.  If we reach that point the network will be controlled by that big boy miner.

Anyway, it wouldn't be so bad for bitcoins.  The top miners bring something valuable to the network :  a huge CPU power.  This improves the network stability and security.  It's normal that this is rewarded.


More incentives for little people to mine, the more CPU power we get.

Indeed.  We should write a "Why you should mine" document.  We would explain why it is important to contribute to the CPU power of the network, even if it is likely that this will not be rewarded in bitcoins.

I think people should keep hashing anyway.

From an individual point of view, it's not very interesting.   But many small computers make a significative CPU power, so it's good from a community point of view.

Therefore I think we should keep encouraging people to mine, even if they only have small computers.
3615  Bitcoin / Bitcoin Discussion / Re: Bad probabilistic news for small-time miners on: November 24, 2010, 08:13:48 PM
Hiya folks, I've done a bit of calculation and there's bad news.  If you're still generating on your CPU, you'll probably never get to generate another block.  I have 26Mhps, and there's a 6.5% chance that I'll never get to generate a block again.  And, of course, as the difficulty increases, it's gonna get worse.  See the attached pdf for details.  The bones is that you calculate the probability of generating in each window of difficulty adjustments.  Since the difficulty is exponentially increasing, your chances of getting blocks are exponentially decreasing.

Hum, thanks for that.  I'm reading it. 

One question.  When you compute \lambda_10, you obtain :

\lambda_10 = C*h/D

And you compute C = 10 * 86,400 * H_{min}/H_{max} = 0.0002 s^-1

Are you sure C is in the dimension of seconds^-1 ?     I think it's rather in seconds.

One thing you did not take into account is the fact that you will probably buy other machines in the future. 

Anyway, it's an interesting document.  Thanks again.  It should be in the wiki or something.

Thank you, Bruce.

Yes, it is very real -- I promise. Scouts' honor! Smiley


I'll try that soon.  I'll try to buy a Vim t-shirt with bitcoins.  I've been wanting to buy one for some time now.  I'll use this as a pretext to do so.
3618  Economy / Trading Discussion / Re: How many bitcoins is "enough"? on: November 24, 2010, 06:21:10 PM
I'm still mainly hoarding at the moment. But I don't intend to keep it that way.


Idem.  I hope there will be more stuffs to buy in the future.
3619  Economy / Trading Discussion / Re: How many bitcoins is "enough"? on: November 24, 2010, 06:20:07 PM
The goal of this project is to create a better vector for the transmission of value - better money.

We need this better money to conduct our commerce. To trade and create wealth.

Do not horde the bitcoins. Spend them. The have no inherent value, their value is in their utility. To not spend them removes that value.

If you want to horde money with no inherent value, there are lots of bullshit national currencies. If you want to save up and invest in your future, use gold.

Accept the bitcoins for business. Spend the bitcoins for business. We need an economy, not some pretend commodity trading game.

I partially agree.  Indeed there is no real point in hoarding any kind of money.  There are much better ways of investing :  shareholdings, precious metals, gov. bonds (if you like this crap), and so on...

However, saving money is not that bad either.  It's pretty much a matter of personnal choice.  But I don't think it's bad for an economy.  Besides, "economy" in some languages (such as french) litteraly means "savings".

I'd say it's ok to save in monetary units when you have some value to preserve, but you don't trust any other asset.

What madhatter has done is nothing short of Brilliant!

His new http://bitcoin2cc.com lets anyone shop anywhere with Bitcoin.

I now link to it directly from the top of http://BitcoinShop.com   (And I redirected BitcoinCard.com to his page. )

Bravo!


OMG  If it really works as it claims, it is just REVOLUTIONNARY.

It seems so awesome I have difficulties believing in it.
