Anything as user friendly as the GLBSE out there? or on its way?

Depending on what you are looking to trade on MPEx, CoinBr might provide it:

I only find instructions about importing the JSON wallet to Multibit, I can't find nothing about importing it to the standard Bitcoin client.

Anyone knows how to do it?

If you have a list of private keys, you can import them using the debug window with the command importprivkey.

So I want to buy 3 BTC via PayPal....

About the only method to use PayPal for purchasing bitcoins is through VirWoX.  There you use PayPal to purchase Second Life Lindens (SLLs).  Then from there you can trade them for Bitcoins on their SLL/BTC exchange.

does anyone know why my trades shown on the picture below have negative profit? I bought 2 contracts at 20.00$ and 20.05$, then sold at 20.5301 and logs show that I lost...

2013-02-02 Buy $20.00
2013-02-02 Buy $20.05

Then later that day after you bought, clearing was $20.7095, so on the two positions you were paid variation margin due to the clearing price of $20.7095.  Then on 2013-02-03 the clearing was $21.0750 and you earned even more. 

Then each day the clearing price was lower so your variation margin was negative.  Then you sold at $20.5301 which was lesss than the most recent  previous clearing price -- $20.8101.    The very last transaction in the log is the 0.5% trading fee.

So your trade resulted in half a percent trading fee when you bought (the two 0.005 BTC trading fee) plus the half a percent trading fee when you sold (the combined 0.01 BTC trading fee entry) and the sum of the margin variances.  Now remember, the variation margin is calculated as:
 VM = -(1/PriceClose - 1/PriceOpen) * S;
which is
  (-(1/PriceClose - 1/PriceOpen) * 10) * N contracts

For instance, the last variation margin had a clearing price of $20.8101 and you sold at $20.5301.  So the variation margin was:
  VM = (-(1/$20.5301 - 1/$20.8101) * 10) * 2 contracts
  VM = (-(0.0487089687 - 0.0480535893) * 10) * 2 contracts
  VM = (-(0.0006553794) * 10) * 2 contracts
  VM = (-0.0065537940) * 2 contracts
  VM = -0.01310758 BTC

(somewhere the calculation must be getting precision issues, as my rounding at 8 decimals is off by a really small amount from the 0.01310526 reported in your pic.)

my account identifyer at Blockchain.info is not being recognized and I took my time to write it

Does your browser history not show the URL?

When you do regain access to the wallet make sure to go into the account details and enter your e-mail address and/or set an alias for the account so that you aren't entirely dependent on knowing the account identifier.
2166  Bitcoin / Technical Support / Re: Taking forever to get confirmations on: February 06, 2013, 02:50:32 AM
Does anyone else have this issue? Is there a remedy for this somehow?

Bitcoin wasn't designed to be good at doing transactions the way it is being used for SatoshiDICE wagering (small amounts and/or spending of coins that were only recently received.)

You might want to find an alternative wagering service that doesn't require a new transaction for each wager.  bitZino, who also offers "provably fair" wagering, has a roulette game which accepts 0.01 wagers (or even smaller amounts) and might be a good alternative to a blockchain-based wagering service.

I notice in the JSON data for n-transactions there are two missing values:

Missing are: Aug 25, 2012 and Dec 12, 2012.

Please try version 3.31 (https://play.google.com/store/apps/details?id=piuk.blockchain.android) released today and let me know if the issues are not fixed.

I couldn't install the app on my Nexus7, then I read the description:  
Quote
*** Please uninstall the old Blockchain app ***
- https://play.google.com/store/apps/details?id=piuk.blockchain.android

And since the old app no longer appeared in the list of My Apps, I had to use the Apps management from Settings:

So just thought I'ld share that.

How about making this for bitcoin?

Related (from another thread):

Looking forward to the LocalBitcoins mobile app.

A few months ago was a StartupBus competition, and one of the contestants was Open Wallet app:



Here's their proof of concept video:

 - http://www.youtube.com/watch?v=QoRlyPZ3zJ0

I have no idea what they were going to use to settle payment to the party acting as "ATM".  I wouldn't doubt they had no good solution ... and left it as "and magic happens here", after figuring out that PayPal wouldn't work for this.

If that was the hurdle these entrepreneurs couldn't solve, then had they considered using bitcoin as the settlement currency they might have been able to get funding, develop it and launch.

Well, ... will LocalBitcoins take it further?
2170  Economy / Speculation / Re: A more in-depth BTC/USD analysis... on: February 05, 2013, 12:48:55 AM
Personally, I'm planning to buy a large amount of BTC right away. But I'm actually going to transfer it all to my new MtGox and exchange accounts to sell and hold in the form of fiat,

I'm a little confused why you'ld do that.  Doesn't that cause you to incur exchange fees three times?  Buying, selling and then eventual re-buy?  Why not transfer fiat and just pay exchange fees once?
2171  Bitcoin / Technical Support / Re: .14 BTC transaction fee? on: February 04, 2013, 07:41:09 PM
Is this ammount of a fee normal for this ammount?
l
The trx fee computation considers the age of the coins (if you recently received them, like in the past day) and the size of the transaction ( where many small inputs are worth less to spend than the amount of fees they require when trying to spend.)

One approach might be to send just a lower amount and let the rest "age" for a day or so if that is the cause it will diminish on its own.  The other approach us to import keys to a client that allows yoy to send trxs without paying any fee.  Blockchain.info/wallet being one of those.

Regardless, make sure you back up your wallet.dat.

What's the algorithm the hash uses and how was this determined?

A bitcoin address is a derivative of a hash of a private key.

Quote
A Bitcoin address is a 160-bit hash of the public portion of a public/private ECDSA keypair.
- http://en.bitcoin.it/wiki/Technical_background_of_Bitcoin_addresses

 - http://en.bitcoin.it/wiki/Private_key
 - http://en.bitcoin.it/wiki/Address

A transaction requires cryptographic signature(s) made using the private key(s) of the input addresses:

 - http://en.bitcoin.it/wiki/Transaction#Principle_example_of_a_Bitcoin_transaction_with_1_input_and_1_output_only

A block includes a reference to a prior block and includes zero or more transactions that have occurred since that prior block:

2013-02-02 Page views number wrong?

Seems way off as other recent days are closer to 400k.

The webserver is now nginx instead of Apache.  I wonder if there are pageviews that don't hit the database and thus aren't being computed.[/quote]

Is there a way to know the real number, or if that is the real number what is the explanation. If it is wrong can it be corrected?

Really messes up the chart correlating the exchange rate compared to forum activity, eh?
2175  Bitcoin / Mining / Re: Butterfly labs single SC on: February 04, 2013, 02:47:04 AM
how many bitcoins in total do you think it will generate? if you had to guess.

A guess is all that it would be because we don't know the future difficulty levels.  Future difficulty levels are dependent on cost and availability of ASIC hardware, as well as the future exchange rates.
2176  Economy / Economics / Re: Which country will be the first to use gold? on: February 04, 2013, 02:28:24 AM
1 India, since gold is already widely distributed amongst the population.

Also interesting are these plans from the RBI (India's central bank):

Quote
It wants banks to encourage products linked to accepting physical gold as deposits and investing public money in gold related products, and extend loans against gold as collateral.

Indians own about 20,000 tonnes of gold, or three times the holdings of the U.S. Federal Reserve, in jewellery, bars and coins.

Which country would use gold

From another thread:

It took decades but finally the government of Kelantan (a state in Malaysia - They have a federal system like the USA) last year listened and introduced Gold and Silver currency which is legal tender in that state. They are even paying civil servants using it.

Quote
Another Malaysian state (Perak) has now introduced its own Gold Dinar and Silver Dirham coins. Kelantan was first, in August of 2010.

In place of VIRES IN NUMERIS, they'd say 0.01 BITCOIN.[...[

[...]
I'd just make them available as roll-your-owns, with the spot on the back for a private key).

[...]
The only thing stopping me is

I'ld be more concerned about being the "issuer" of a coin marked 0.01 BTC  (where 0.01 BTC is worth about twenty cents today) which is [potentially going to be] floating around without any 0.01 BTCs on it.

[When I try to send, I get the message: "Insufficient funds. Value needed XXX BTC. Available amount xxx BTC

Just out of curiosity, have you tried using the transaction type "Custom" instead of "Quick Send"?  That way you can select which inputs are used and you can even set the fee to 0 (or whatever value you wish).    That might help to resolve your issue.
