This is the link to the viabtc transaction accelerator. As squatz1 pointed out it frequently gets overloaded with acceleration requests so you have to keep trying a few times an hour until it accepts your transaction.

2782  Bitcoin / Bitcoin Technical Support / Re: 25 btc stuck - Transactions allways stuck, scared to sell btc now cause of this on: March 07, 2017, 03:50:00 PM
*snip*

I then had to send bitcoin urgently because I needed to cash out to pay my rent yesterday, sent it with the f**** maximum fee electrum lets me put (0.001 BTC/kb), guess what, all day stuck; took 24 hours to get 2 confirmations and I am still waiting for the third one to be able to sell them with my rent that should of been payed yesterday a few hours after I made the transaction still unpayed.

Am I still missing something or is this what bitcoin is going to be like from now on -stupid and unusable?


There seems to be an electrum bug affecting a few people that limits the maximum dynamic fee to 0.001 BTC/KB. You can fix it by opening preferences and unchecking, then rechecking "use dynamic fees". After I did that the maximum dynamic fee in my wallet increased to 0.003 BTC/KB yesterday.

Two other people who posted in the thread quoted have also experienced that bug.

*snip*

As a test I freshly installed the latest portable wallet (version 2.7.18) in a new folder, then made sure only "use dynamic fees" was checked in the preferences as shown below.





The maximum fee shown on the dynamic fee slider was 0.001 BTC/KB as you can see below. Although I tried switching to manual server selection, and tested numerous different servers, the maximum fee remained 0.001 BTC/KB.






Finally I unchecked "use dynamic fees", then rechecked it again, and that fixed the problem. The maximum fee shown on the dynamic fee slider increased to 0.003 BTC/KB as you can see below.




Unchecking, then rechecking "use dynamic fees" fixes the problem.

Nice beartrap ...



What kind of an idiot sells any kind of substantial amount of coins right now when the price could be literally anything ridiculously high in years to come.

The same kind of idiot that dumped at the red arrow less than a month ago. That was a worse bear trap than this one.


2784  Bitcoin / Electrum / An electrum docs website link is redirecting to phishing sites. on: March 07, 2017, 02:37:52 PM
Today I clicked the link marked "tutorial: How to create a plugin" on the electrum docs website, and it redirected me to a phishing site. The link's marked with a red arrow on the screenshot below.





This is a virustotal scan of the first site I was redirected to.

https://www.virustotal.com/en/url/d493df45c5989d0a0822458327abcc637b6a5e72d2f00ff26c34b4a8b2aa9147/analysis/1488897009/

I was very quickly redirected to another site afterwards. This is a screenshot of the second site.





This is a virustotal scan of it that says it's a phishing site.

https://www.virustotal.com/en/url/0fc2c2c8bdcba360946c08c47ce3c7fa7ea7222b10e8b273197d192ad02c9fa2/analysis/1488897538/

After testing the "tutorial: How to create a plugin" link again I was redirected to a different site that virustotal said was clean. However it was trying to sell me some dodgy investment scheme.

DON'T CLICK THAT LINK ON THE DOCS WEBSITE.

You might be able to speed the transaction up by using the site linked here.

https://www.viabtc.com/tools/txaccelerator/

However, it your transaction must include a minimum 0.0001BTC/KB fee to use the site. If your transaction's fee is lower than that you can't use it. The site's very popular, and only accepts 100 transactions an hour, so you will probably have to keep trying it a few times an hour until it accepts your transaction.

What's the news again?Smiley

Sorry but can someone explain what is the news? looks like bad situation here and incoming sell - not to say dump....


BTCC told its customers it would allow withdrawals again by March 15, but there are emerging reports that some customers have already had their frozen withdrawals processed. That couldn't be the reason for the dump could it?

Personally I think most of them will simply withdraw to their own wallets rather than dump.

https://cointelegraph.com/news/bitcoin-exchange-btcc-tests-withdrawals-before-deadline-localbitcoins-set-records

Quote
Major Chinese Bitcoin exchange BTCC appears to be testing withdrawals ahead of the planned March 15 deadline.

A user cited by news resource cnLedger on Twitter appears to state they managed to successfully withdraw Bitcoin from their account.

Despite the request being made before BTCC halted withdrawals Feb. 15, it has now nonetheless gone through, prompting positive speculation.

Whatever the reason was for the dump it's back up to $1222 on stamp already.

Unchecking, then rechecking "use dynamic fees" fixes the problem.

Did you have a server connected when you first checked the box. The data comes from the server.

Yes I had a server connected, and I tried switching between multiple different ones. As far as I remember each time I switched server the circular icon at the bottom right changed from green, to red, then back to green. The problem still remained until I unchecked, then rechecked "use dynamic fees".

I didn't test what happens when sending coins because I had none in the freshly installed wallet.

It sounds like the box is checked by default in the UI but not really registered in the config file as enabled, so it looks to be enabled but isn't truly enabled.
Today I encountered the same problem. I followed as HI-TEC99' s instruction above post, the issue was resolved.

Did you try sending any Bitcoins while the maximum dynamic fee setting was too low?

Yesterday I sent some Bitcoins to a freshly installed wallet, and tested if the maximum slider setting still showed a low fee, and it did. There was such a big backlog of transactions in the network that I didn't test actually sending them. If nobody else does it first I'll test it when the network has less unconfirmed transactions.

This is the maximum fee my new wallet showed during yesterday's test.

Ok. what's going on?

dump is biggest in china. we will see some PBoC fud soon i assume.

more Woo BU FUD ... so yeah probably PBOC pulling their commie strings thing ... powerful people disappear all the time over there if they don't do what the People's Party asks them to.


Cryptocoinsnews reported the latest PBOC news. A top official says China should look at international efforts to regulate Bitcoin. He also wants to make a ‘negative list’ of Chinese Bitcoin exchanges, whatever that means.



https://www.cryptocoinsnews.com/101937-2/

Quote
Today, a central bank official has reportedly been quoted with saying that China ought to make clear its supposed “bottom line” in its supervision of bitcoin exchanges in the country. A Reuters report cites regional newspaper China Business News quoting the People Bank of China’s Zhou Xuedong, the director of the business management department at the country’s central bank.

Zhou, who is also a delegate of the central bank to the national parliament, has also reportedly called for a ‘negative list’ of bitcoin exchanges in the country as a means to reducing financial and market risks.

*snip*

Alongside his notable quotes in relation to bitcoin exchange supervision today, Xuedong has also called for China to look at regulatory efforts toward bitcoin internationally to establish a regulatory mechanism for the industry.

It'll get to your "news sources" eventually.
Yeah yeah, 50% of being right, 100% expecting "I told you so." by either side who was just guessing about the outcome like everyone else. Give me a break.

1 day ago there was someone with 'insider' info claiming it will be announced tomorrow with a positive result. One of you must be right. Roll Eyes

I have about as much faith in his "insider info" as I had in monsanto's conclusion that the winky's posting a picture of doughnuts mean't Gemini's launch was imminent a year and a half ago. Nobody knows anything yet, and we'll just have to wait to find out.

Why post this? Could this have a hidden meaning -- a donut is also a symbol for zero. If Friday was day zero then Gemini could launch tomorrow.  Wink  
2791  Bitcoin / Bitcoin Technical Support / Re: Recovering Passphrase with wallet recovery mnemonic on: March 06, 2017, 10:10:24 PM
If you set a very strong password on a Bitcoin core wallet consisting of both lower and upper case letters, numbers, and special characters there's no way of recovering the password unless you can remember some parts of it.

On the other hand, if you set a weak password of just lower case letters, and can remember some details like its approximate length, or some characters it contains, then someone runs a password recovery service that might be able to help.

These are links to its bitcointalk thread and website. He charges a fee for password recovery, but seems trustworthy. He's been running the service for years now.

Maybe your problem is different, but someone else who got that error found out it was because his transaction was a double spend. You can read about it here.

If you are prepared to post your transaction's ID here we could probably figure out what the problem is.

1000 BTC buy wall @ BITSTAMP @ $ 1275


what is the meaning of this ?

is it gentleman?



We had a good pump after the weekend before last. Perhaps we'll get another good pump this week too. That wall could be due to money from bank transfers arriving in bitstamp again now the banks are open. We keep getting close to $1300, maybe this is the week we break above it.

2796  Bitcoin / Wallet software / Re: Is there a way for me to use a Mycelium HD wallet in Electrum or vise versa? on: March 06, 2017, 02:28:38 AM
I think Electrum can handle the standard (Mycelium) seed standard too. So it should work that way around... At least that's what I think I used to do (before I bought my Trezor), but why not try it and see what you end up with? If they present the same public address you should be good to go.
Guess I'll give that a try. I'll give an update with the outcome.
Just tried it, Electrum doesn't seem to recognize the seed. Perhaps I'll just put up with Electrum being buggy or I'll might just use both.

You probably have to click the options button, then check "BIP39 seed" as in shown the screenshots.











That's how I tested using a multibit hd seed in electrum, but the multibit seed generated different addresses in electrum.


This quote explains how I tested this, and why it didn't work. The same probably applies to a mycelium seed.


I tried importing my multibit HD seed into electrum, but it wouldn't let me import them until I clicked the options button, then checked "BIP39 seed". Although electrum create a wallet using my multibit HD words it didn't show the same addresses as in my multibit HD wallet. Either I did something wrong, or that technique doesn't work.

<edit>

This might be why the technique didn't work

Multibit creates addresses using compressed private key, while Electrum uses uncompressed private keys. You can't decompress key - it will change public address, not allowing you to use your coins.

I do not have any funds in my coinbase account now, 13DHU877EnKy8uvCg2NSWNcSPhdCuMuLLz, but still closing the account without citing any valid reason is not professional. I have read about many complaints regarding coinbase on this forum as well as reddit, guess most of them were true.
2798  Economy / Exchanges / Re: Poloniex api - one exchange only? on: March 06, 2017, 12:07:53 AM

I am looking for total historical volume data per 24-hour period, for all exchanges. Coinmarketcap reports this on a daily basis, but there does not seem to be historical commands (https://coinmarketcap.com/api/).

Look at the bottom of the page at this link.

http://alt19.com/

There is a facility to download altcoin charts and altcoin historical data in a CSV format. It has data at 15 minute, 1 hour, and 1 day increments.


Also, gjhiggins explains how to scrape historical data from coinmarketcap in this post.

Could anyone please provide me with historical data of

* HZ / BTC
* NXT / BTC

... back to early 2015.  Daily precision is fine.

https://coinmarketcap.com/historical/

Weekly precision.

It's pages of HTML tables, so you'll need to roll your own processing which is trivially easy to do with pandas. The defaults returns prices in USD, from which BTC price can be derived by using df.iloc[0, 4] (assuming Bitcoin occupies the first row).

Code:
$ python
Python 3.4.3 (default, Jul 28 2015, 18:20:59)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pandas.io.html import read_html
>>> df = read_html('https://coinmarketcap.com/historical/20151101/')[0]
>>> btcusd = float(df.iloc[0, 4].split(' ')[1])
>>> for il in range(0, len(df)):
...     if df.iloc[il, 2] in ['NXT', 'HZ']:
...         print("{name} {symbol} {btcprice:02.8f}".format(
...             name=df.iloc[il, 1],
...             symbol=df.iloc[il, 2],
...             btcprice=(float(df.iloc[il, 4].split(' ')[1]) / btcusd)))
...
Nxt NXT 0.00002371
Horizon HZ 0.00000041

Close enough for government work, I'd say.

Cheers

Graham

I thought I might have made a mistake, but now I'm fairly sure this is a bug that appears on the first run of a freshly installed portable wallet.

As a test I freshly installed the latest portable wallet (version 2.7.18) in a new folder, then made sure only "use dynamic fees" was checked in the preferences as shown below.





The maximum fee shown on the dynamic fee slider was 0.001 BTC/KB as you can see below. Although I tried switching to manual server selection, and tested numerous different servers, the maximum fee remained 0.001 BTC/KB.






Finally I unchecked "use dynamic fees", then rechecked it again, and that fixed the problem. The maximum fee shown on the dynamic fee slider increased to 0.003 BTC/KB as you can see below.
