please notice that alt coin creators are not developers. they are 'cloners'

its much the same as calling a script kiddie, an elite hacker.

just because they are provided with a script and they maybe tweak 1% of it, doesnt make them talented

I agree with this sentiment overall.  However, please note that the Litecoin and Peercoin/Primecoin core devs are in fact quite skilled*.  All of them are far better developers than I am, and I'm not a bad developer.  Also, at least one of the Litecoin devs participates actively in Bitcoin development (Warren Togami, who is also the founder of Fedora and creator of Spamassassin).

*There may be other skilled alt coin devs, these are just the ones I'm familiar with.

i have spent some, now i have 0.03413408 BTC available, but i should have 0.05577058 BTC as reported on blockchain..
i did a -rescan, still missing btc Sad

You may be affected by transaction malleability, which can result in bitcoin-qt misreporting balances.  See here:
http://www.reddit.com/r/Bitcoin/comments/1xm49o/due_to_active_malleable_transaction_relayers_it/

There's a patch on that page, but this issue is also addressed (I believe) in the latest bitcoin-qt release candidate:

https://bitcoin.org/bin/0.9.0/test/README.txt

So you may need to upgrade to 0.9.0-rc2 to address the issue.  I'm not 100% this is what you're experiencing, but it sounds like it might be.  I did check on blockexplorer, and the balance there matches blockchain.info.  So you likely still have those Bitcoins, just your client is misreporting the balance.

You may also be affected by this:
http://www.reddit.com/r/Bitcoin/comments/1znnmr/warning_something_wrong_with_blockchaininfo_wallet/

It is however not your fault, but Blockchain.com's. You may want to contact their support and tell them the transaction ID.

This is likely what you're experiencing.  Statement: https://blog.blockchain.com/2014/03/05/occasional-unconfirmed-transactions-are-being-addressed/

It appears to have been resolved.  If not, e-mail the e-mail on that support blog or post your transaction id here.

Hello, everybody,

The coins finally came thru. I really worried my ass off for nothing. I thought everyone was wrong about the "just wait" phrases. I thought this was a rare occurrence that could only happen to me, but about 50 hours later, the Coins came!!!!

Thanks a million though for everyone's help and input.

Actually, in this case it probably had nothing to do with Bitcoin directly, but rather with blockchain.info's implementation.  Blockchain.info has been having some difficulties with transactions getting "stuck" the past few weeks.  They've issued a statement about it:

https://blog.blockchain.com/2014/03/05/occasional-unconfirmed-transactions-are-being-addressed/

It appears it has been resolved, at least according to the update they published to that statement.  But the point is, this appears to have been a blockchain.info problem, not a Bitcoin issue.
5  Bitcoin / Bitcoin Technical Support / Re: [GUIDE]Double-spending an unconfirmed transaction made with a third-party client on: March 06, 2014, 11:00:15 AM

Is there any BTC masters out there that could help me with this for a fee?  I would very very greatly appreciate it.


If you post the transaction id, I'm sure someone will help you.  I'll check back here later today to see if you've posted it.
6  Bitcoin / Development & Technical Discussion / Re: Double spending insurance on: January 09, 2014, 05:37:33 AM
Agreed. A pool that accepted double spends would quickly be shunned by the community.

Not sure if you're being sarcastic, but if not, you should have a look at this:https://bitcointalk.org/index.php?topic=327767.0  The pool that enabled the double spend (GHash.IO) basically even concedes that someone at their organization was involved in their official response. 

So a pool has now accepted double spends with little to no consequences: https://blockchain.info/pools

If you were being sarcastic, then you probably already know all about this.

Smiley would think it would be easy.
My biggest request would be the ability to multiply, So we can say Buy @ 95% of current value, Sell at 103%


Just FYI, when you say "ability to multiply...buy...sell", you appear to be requesting a trading platform, not a simple ticker.  Building a full multi-exchange client with the capacity to perform secure transactions is *much* more difficult than building a simple ticker.  A ticker is easy -- a multi-exchange trading platform...not so much.

Few days ago one redditor posted that his drugdealer have 400k :

What did that say before he removed it?  I'm intensely curious.

i don't like the sound of china doing sweeping blocks of btc-related sites. yes we all know they can be got around, but will the average user bother in tightly regulated sphere?

Bitcoin in China is over.  I think most of us have already baked this into our price.
10  Bitcoin / Bitcoin Discussion / Re: Why doesnt someone make a cash only exchange? on: December 19, 2013, 08:33:18 PM
Because one shop would have  to spend bucketloads of money complying with anti-money laundering regulations. Bitcoin ATMs solve the problem in a much more economical way.

What makes you think that FinCEN is going to consider Bitcoin ATMs to be exempt from AML?  Believe me, they won't.  That's why it's been so hard to get them going.

But I agree that cash businesses also must comply with AML if they want to stay out of jail, BUT cash businesses don't have to put up with banks cutting them off at every turn.  And if we develop our own clearing houses....

I have been accepting Bitcoin as payment on my website Tealet, an online farmer's market for tea.

http://tealet.com/bitcoin

We are very happy with the results and I would be happy to tell you my story. Please PM me or contact me at elyse [at] tealet [dot] com.

Cool.  Is your JUSHANG OOLONG the traditional oolong tea that you get at Chinese restaurants?  And it's got caffeine, right? (I *want* the caffeine)

Thanks

What's happened around here is similar to the SA mob in 2011, just applied to market manipulation instead of merely to troll.

I agree, but if you think it's bad here, you should see how bad it has gotten the past 2 days in /r/Bitcoin , which was already suffering from a drop in quality as more get-rich-quick types flooded the reddit.  But the past 2 days it's really gotten unbearable.

Go any more Bitcoin insights?
14  Bitcoin / Project Development / Re: easy offline transactions - 1 BTC bounty on: May 30, 2013, 11:35:35 PM
Hey, no worries. Good to see you may still work on it Smiley

Personally I risked using the prototype version above for my most pressing needs.

Yes, my ultimate goal is to get it where people can easily run *both* the online version and offline version locally, with no need to host the online version.  It's a little tricky because of the problems that exist making request to third-party websites from a locally-running javascript program.  Really, this is the only secure way to do it.  SSL for the online portion is nice but still requires the user trust the person serving the site.  Running both portions locally, on my online and offline computers, is the only way I'd consider using this project for a significant offline transaction.

Anyway, this third-party request issue is partially solveable using CORS headers, and blockchain.info has recently, and very kindly, implemented CORS headers for this type of use case.  Anyway, I worked on it some more last night but ran into some very serious issues with AngularJS (the JS framework I used) HTTP client implementation and CORS compatibility, so I've ended up using Jquery to call blockchain for unspent outputs and to push the signed transaction (which works fine).  Anyway, I still want to do some more work before I announce it ready, and although I won't get to anything tonight, I should be able to finish up this weekend.
15  Bitcoin / Project Development / Re: easy offline transactions - 1 BTC bounty on: May 28, 2013, 04:00:28 PM
Good move - will wait for that - I think this is the right way to go and appreciate the effort (I actually wrote something similar but is much less user-friendly as it requires you to find the UTXO information manually).


Thanks for your understanding and sorry for the inconvenience to anyone who has been waiting on this (i.e., xDan).  I'll be sure to check this thread on a regular basis now.

I'll post an announcement here tonight or tomorrow when it's ready for beta testing.

EDIT: Had to work late last night, hopefully will get to it today.
16  Bitcoin / Project Development / Re: easy offline transactions - 1 BTC bounty on: May 28, 2013, 03:43:17 PM
After thinking about it some more, may I please ask everyone to please hold off on using any version of this?  I didn't realize anyone was still interested in it until a few hours ago.  However, it's got some bugs I want to iron out before anyone uses it.  I originally said to use my hosted version at https://bitcoin-secured.com since it was better than using an unencrypted version of the online part, but after thinking about it, I'd prefer people hold off on using it at all until after I do some additional testing tonight, when I'll have time to do so (can't shirk my work duties anymore right now).  You are of course free to do anything you want with the code, since it's MIT licensed, but I'd prefer people hold off until I can do some additional testing.

I'll make an announcement here when it's ready for beta use.
17  Bitcoin / Project Development / Re: easy offline transactions - 1 BTC bounty on: May 28, 2013, 03:32:57 PM
Okay - found the repository (https://github.com/esbullington/bitcoin-secured) - apart from Python any other dependencies?


Python is technically not a dependency.  It's just what I used to serve it locally.  It's all static HTML, JS, and CSS, so you can run it from wherever you usually run such scripts.

Can you hold off for a day?  Or else update it tomorrow?  I'll be making some significant changes tonight, like better error handling, etc.

And again, I'll note that I have an SSL-encrypted version at https://bitcoin-secured.com that includes signed MD5 hashes of the offline code for download.
18  Bitcoin / Project Development / Re: easy offline transactions - 1 BTC bounty on: May 28, 2013, 03:11:33 PM
Or wait for someone else to host it on an SSL-enabled URL.

If you have the source on say github then I will be happy to grab it and put it somewhere under https://ciyam.org.


Thanks for the offer!  The source is on github (I'm esbullington on github, the link is somewhere above), so please feel free to do so, but I do have it on https://bitcoin-secured.com which is SSL.  It's just down for a few minutes while I'm updating it.  So I'll have it back on an SSL-enabled site real soon.

Users who use the online portion of bitcoin-secured hosted by a third-party should make sure that

1)  It's SSL-encryped
2)  It's someone you trust

The best way to run the online portion is locally, simply by going to the `bitcoin-secured/online` directory and then running: python -m SimpleHTTPServer

The site will then be available at localhost:8000

Since blockchain.info is now using CORS, this should work, but I've not yet tested it (working as fast as I can to do so).

PS: Please note that I have signed MD5 hashes of the offline code that can be downloaded at: https://bitcoin-secured.com/#/download
19  Bitcoin / Wallet software / Re: blockchain.info HTTP API support for CORS? on: May 28, 2013, 02:54:51 PM
You can now add a cors=true parameter to most requests if you need the header e.g.

http://blockchain.info/unspent?cors=true

Great, thanks so much!
20  Bitcoin / Project Development / Re: easy offline transactions - 1 BTC bounty on: May 28, 2013, 02:41:18 PM
Good news.  blockchain.info now supports CORS so I can connect directly to them while I'm finalizing my own local database of unspent ouputs for bitcoin-secured.  I'll try to push the new version out tonight.  Right now, the script relies on Yahoo to relay the request, which means that blockchain.info's API request limit is quickly reached if a lot of people use it.  This will solve that problem.

NOTICE: bitcoin-secured will be offline shortly will I update it to supports blockchain.info's CORS.  While it's down, please be aware that if you use a non-SSL link for the online version of this software, it's very vulnerable to someone swapping out your Bitcoin address for another.  Either use https://bitcoin-secured.com when it's back up or run it locally (on localhost).  Or wait for someone else to host it on an SSL-enabled URL.
