2161  Bitcoin / Bitcoin Technical Support / Re: Cryptonator bitcoin send issue, transaction is not shown in blockchain on: December 09, 2017, 12:07:13 PM
Can you please help me answering my questions : Are my bitcoins safe? if it takes time then what can be the reason?
Even if my transaction is Unconfirmed it must be visible on Blockchain, why It shows message that Transaction is not found?

Its hard to awnser what exactly happened in this case.
The mempool is congested at the moment. If cryptonator chose a fee which is way below the 'standard' currently the transaction might got dropped
(in the case the TX hasn't been rebroadcasted). You should contact the support of cryptonator and tell them their transaction never went through.
But it seems like quite a few people had issues with cryptonator (including issues with their support). You might consider to change your wallet.

Ok but if this transaction will get dropped then shall I get auto reversal of my bitcoins to cryptonator account? Or do I have a risk to loose bitcoins? Thanks

If nothing gets confirmed or broadcasted to the mempool, then it would make sense that they are going to be returned to the adress you were trying to send them from, ( as no transaction could be made...)

Unless you are using a really shitty service which doesn't automtically credit you back the bitcoin, you should be just fine.

Ok Thanks for your guidance. so now I will wait and keep sending cryptonator emails about this issue. Can you  please help me find best and secure bitcoin and monero wallet please..

Why not use a software wallet where you are 100% in control over your private keys, adresses, and transactions you broadcast? I'm not sure why you would want to use a webwallet.

For bitcoin i'd recommend you to use something like electrum, and for monero i'd either recommend using their official software wallet, or something like exodus, where you can store both your bitcoin and monero. (Although i don't think exodus supports monero yet, so you should look for something like that)

2163  Other / Beginners & Help / Re: 70 confirmations but i have not received the bitcoin... on: December 09, 2017, 10:25:39 AM
More details required. Which wallet you are using? Is the wallet up to date? Synchronized?
i just closed electrum and launched it again and then the coins appeared. i didnt know i have to restart electrum wallet after every transaction. but this is good to know! thank you!


You were probably disconnected from the network, hence why nothing was updated. As far as i know there's absolutely no need to reboot electrum every time you get a transaction.

The node you were using might went down, and you forgot to reconnect to another one?



Was this green dot by any chance red?
2164  Bitcoin / Bitcoin Technical Support / Re: Linked Addresses on: December 09, 2017, 10:12:52 AM
when a user uses online wallet like blockchain.info it gives him more than 1 address like

new address : 13nYYLitRDrSuUfFRThYZaZQeDpx618cYs   /   first address :1AFR9EQ9cFiaFhs5gE1vFE4foPDghX5x48

How to know those two address from the same wallet?

what’s the right word on a google search to get more about this topic?

That's one of the disadvantages of using a wallet like blockchain.info, you can't see all of the pregenerated receiving adresses etcetera, ( as far as i know), and neither are your private keys easily accessible.

What you can do is put the adress into something like https://www.walletexplorer.com/wallet/0729db5ddd132004/addresses, to see from which wallet it is part of.

Note that this will only work when the adress has ATLEAST 1 incoming TX/ confirmed TX.

Newly generated adresses won't show up with the corresponding wallet.


you could manually create new adress using this guide, https://support.blockchain.com/hc/en-us/articles/207746403-Addresses
2165  Bitcoin / Bitcoin Technical Support / Re: Help TRX ID does not exist on: December 08, 2017, 10:20:12 PM
Hi, After 24 hours my transaction ID still does not exist - I'm worried I will lose my bitcoin. Does it come back at some point? Please help!

f3431e9b795b1645d1feed966ed06fb947644dca117acfe9f2354e4811a6d6fb

Depends, were you using a service to create the transaction? If not, you should be fine, and you probably did something wrong while broadcasting your transaction to the network.
But then again, that depends on the wallet you're using, i can't really help you without it.

try to look up the values of the tx in your console when using bitcoin core, using
Code:
getrawtransaction
Code:
f3431e9b795b1645d1feed966ed06fb947644dca117acfe9f2354e4811a6d6fb

( To see if it's signed and in your own mempool, if so, try to rebroadcast it either through your own wallet or a web api such as https://coinb.in/#broadcast)

If you are using a service, then there might be something wrong, and it would be smart to contact their support.
2166  Other / Meta / Re: Bitcoin is insanely slow? on: December 08, 2017, 10:12:37 PM
It's often taking more than a minute to load a page of Bitcointalk. I don't know what's causing this, but sometimes Bitcointalk is very slow and it's so horrible that I'm not using it at those times anymore, although they are often the times I can be available the most.

So my question basically is... Why the heck is Bitcointalk so slow? And is there anything I can do about it? Or is there something that will probably be done about it soon?

I've asked this a couple days ago, there supposedly, according to theymos, was a DDOS attack going on at the time. Pages have been loading slightly faster since, but it is still nowhere like it used to be.

It's a DDoS, I'm working on it.
https://bitcointalk.org/index.php?topic=2484738

I'm guessing that there's just lots and lots of people browsing bitcointalk, due to the sudden increase in price of bitcoin.

See coinbase, bitstamp et al, all had record traffic last week.

Don't think there's much you can do unfortunately....
2167  Other / Beginners & Help / Re: recovering old wallet? on: December 08, 2017, 08:05:29 PM
12 words, usually that would be Electrum or blockchain.info since there also is an option for you to receive your 12-word mnemonics on both, the difference is that in blockchain.info you are given a wallet identifier to decrypt your wallet. Have you tried downloading Electrum and see whether you'll come up with anything? Also, try blockchain.info and see whether it will work or not.

He did have an email from blockchain.info (I know it is not electrum), but he cannot get in with the 12 words on the attempts he said he made.  He said he tried recovering the password there with the 12 words but it does not work.
Any ideas as to why the 12 words wouldn't work?  Thank you.   

Where did he try to fill in the twelve words? I believe Electrum & blockchain.info might use different derivation methods, which is why it might not work.

Try to enable BIP39 seeds in electrum, and try again.


Also, check the word list, to see if all the words in the seed are correct.

Not entirely sure but i believe blockchain.info uses this one https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

How does a block erupters inner workings work?

I believe it is a USB mining "tool" which uses ASIC (

2169  Bitcoin / Bitcoin Technical Support / Re: Sending Coins on: December 08, 2017, 07:09:15 PM
No I owned the coins on a phone app I tried to transfer them to a different app all together on my ipad. I filled out the amount to transfer which was $20.00 and didn't fill in anything under the Pay to section and hit the send button. It now shows a negative of $24.00 so I'mm asking where is went if their is no sending address?

Is it gone or should the transaction not even go through if it has no name or address to send?

Thanks

If there's no adress specified i don't see how it could possibly go through.

What app are you using, and could you provide some screenshots of what you're seeing, or a transaction ID, since it should have one if the TX went through, which should also included where you sent the bitcoins to.

2171  Other / Beginners & Help / Re: Timeframe to real money on: December 08, 2017, 05:53:40 PM
So I have the whole mining vs buying crypto concept in hand now, and the fact that crypto is generally viewed as property rather then money, but after all, the reason to get into this is to see some real money over time, right?

So the questions I have is,

1) on average, from the time you list crypto for sale on a trading site, how long does it take to actually sell?

and

2) Does it sell for the actual market price at that point it time or is there "bartering" that goes on?


Thanks for any help!

1) That depends on the price you sell it for, and the volume.

If you sell a coin for 0.01BTC, while the actual price is 0.001BTC, it surely won't get sold for a while.

If you sell something for 0.001BTC, and you have the lowest sell order, but there's no liquidity/volume, it might take some time before someone buys it.

2) If you sell something for the actual market price you fullfill a buy order someone placed there at that price. I don't think that bartering.
2172  Other / Beginners & Help / Re: A couple of questions for new Bitcoiner on: December 08, 2017, 05:44:55 PM
So I've downloaded and run the Bitcoin Core client and synced it, set up a passphrase and backed up my empty wallet and written down my privatekey.
Do I need to anything more before buying bitcoins?

I've looked at Localbitcoins for buying bitcoins - but I know they have a fee. As soon as I make a user at their site I assume I get a new wallet and new privatekey through them? And if so, can I then transfer those bitcoins to the wallet I have in Bitcoin Core without having to pay a fee over again? after all those are both my own wallets.

And last - I don't have an offline computer - but want to keep my wallet stored and backed up safely. As I dont intend to use it all the time but store it I'm thinking if I can simply compress the wallet.dat with a strong password, and store it at two locations thus meaning I both have a backup of it and also keep it away from access to others - will this work? There is no need for the wallet or so to be connected to the grid? If I later 5 years from now uncompress the wallet.dat onto a brand new computer I will still be able to access the bitcoins in the wallet provided I have both my private-key and my passphrase ? Do I need a second thype of key or address?

Hope those are questions easily understood - please reply if you know the answer, or ask away if there are some of my questions that are hard to understand Smiley

Not really, just make sure the environment of bitcoin core is clean and secured against any viruses etcetera. ( although this still shouldn't matter if you encrypted it )

You should indeed be fine, although i wouldn't really recommend compressing it, because there's really not that much space to gain --, and it might become a bit of a hassle.

If you buy them from say, Coinbase, you will need to pay a network fee above the fees you already paid for your purchase, if you want to transfer them to a wallet outside their ""Network""


2173  Bitcoin / Bitcoin Technical Support / Re: Transaction stuck, i pay **500 dollar Tip** on: December 08, 2017, 03:22:50 PM
I doubt you can get it "unstuck" without increasing your fee to some unacceptable level.  There are currently 211,000 unconfirmed transactions:
https://jochen-hoenicke.de/queue/#2d

Not if a miner prioritizes your transaction, which i believe has already been done by the posters above.

They usually don't require a fee of more then 5s/byte, which is extremely low right now.

Your transaction will simply be put in first if they find a block. No matter the fees.

As far as organic transactions, yes, you're right.
2174  Bitcoin / Electrum / Re: what is electrum server?any tutorials on: December 08, 2017, 03:04:01 PM
What means electrum server
Any tutorials
And what is the relationship between electrum server and node?
How to set it up? When to use it?

I believe the Electrum server just functions as a full node with some extra compatibility for the electrum wallet. ( Which are necessary for electrum wallets because they aren't directly relayed to normal nodes of the bitcoin network??, )

There's some good guides on how to install either ElectrumX or electrum-server, and how to either publicly host it, or for own personal use.

2175  Bitcoin / Electrum / Re: Incorrect Balance on: December 07, 2017, 09:11:45 PM
Hello Community Members,

I am currently using Electrum to store my coins and recently spent a small percentage, I have noticed that the balance that is displayed on Electrum is incorrect. How do I rectify this? It's missing £516.51 on time of posting. I have also noticed that the value of 1 BTC isn't updated periodically. Any advice would be highly appreciated.

Thank you,
makkie

How much did you spent, and did you check where the rest of the bitcoin went?
(As bitcoin spents all the bitcoin available on an adress when an output is made, say there's 5BTC on the adress, and you "sent" 4BTC, 5BTC will be spent, and 1BTC will be returned to a change adress.)

I could help you if you either PM or post the transaction you made.

Did you maybe set up a change adress of which you do not control the private keys / or isn't listed in your wallet?
2176  Bitcoin / Electrum / Re: ELECTRUM - Why the hell am I losing so much BTC for a send transaction?!?! on: December 07, 2017, 08:47:12 PM
Hi there and good evening. I am getting quite frustrated by this problem as I am trying to move BTC out of my wallet in order to claim my Bitcoin Cash, but just sending my funds to another wallet is giving me a headache!

So, if you check out the image below you can see what I mean, so I selected the max amount to send and have the lowest fee selected, that is all good, but the problem lies in the numbers. 

So you can see at the bottom that I have 0.33745BTC, but the max amount I am able to send is 0.3172592. This in no way correlates with the sending fee of 0.0001908, which if taken off of my actual savings would leave 0.33726BTC still to be sent. At the moment the fee it shows is actually around £2 but if you look at my savings amount and the sending amount I would be losing out on around another £200 for my troubles.



It would be nice if someone could help me with this situation as literally all I want to do is transfer from one Electrum wallet to another without any ridiculous fees!!


Could you maybe list the adresses you want to spend from?

It seems to me that you are probably trying to make a transaction with either dust in it, or a very large number of outputs, which usually results in - ridiculous -, but mostly necessary fees.

see https://bitcoin.stackexchange.com/questions/10986/what-is-meant-by-bitcoin-dust

2177  Bitcoin / Bitcoin Technical Support / Re: Bitcoin Core Wallet - Auto rescan after private key import on: December 07, 2017, 05:12:30 PM
Hey fellow Bitcoiners

Everytime that I import a private key into the Bitcoin Core wallet ( importprivkey ) the client automatically starts rescanning. But I want to be able to import several private keys then convert them to segwit addresses ( addwitnessaddress ) then finally do a full rescan.

Anyone know how to turn off the auto rescanning after importing a key into Bitcoin Core?


Not sure how you would turn it off, ( As i don't think adding an argument is possible?) but you do can either import multiple adresses using

Code:
 importmulti

Which means that for 10 private keys you import you only need to rescan it once.

I also think you can add a custom
Code:
timestamp
, which determines from where the rescan will take place, ( 0 = genesis block?)

2178  Bitcoin / Bitcoin Technical Support / Re: PRIVATE KEY on: December 07, 2017, 03:55:58 PM
Wow man thank you so much for the timely response so if I intend on keeping my bitcoin and I want to move it say to a trezor, once I transferred over will it automatically populate my private key for me at that point which I can then hand write and put in the safe and what not? Also what about my stock in alt coins, do i need their private keys too? Do they even have them or should i just continue to use Brittrex for that type of trading? Thanks again.

Trezor actually uses a "seed" (24 words) for backup, so that will be the only thing you need to save, if you want to secure/ backup your funds.

You could also save your private key, but then you'll first need it to convert it to a private key, see https://www.reddit.com/r/TREZOR/comments/6hvgiz/can_i_see_my_own_private_key_on_the_trezor/

Using a BIP39 tool, which is a bit of a hassle, see https://bitcoin.stackexchange.com/questions/54615/can-you-ever-view-your-private-keys-on-the-trezor aswell.

If you want to be in absolute control of your coins, then you should. Your altcoins will be gone aswell if bittrex gets hacked / goes down in the future.

Newbie here:::

I bought bitcoin from Coinbase back in July haphazardly to play online poker on Betcoin. I couldn’t get it to work on my Mac computer and forgot about it and left it in betcoin. Sense the market is going up I’ve gone back and tried I had good success in doing that I got it back into Coinbase and I actually ended up buying more but I have not been able to find my private key. I’m not sure where that would’ve been given to me by Coinbase. Would that of been back in July when I first bought? I’ve have since taken all my bit coin and transferred it to Brittrex and I also still cannot find any type of private key for my bitcoin where can I start? where can I retrieve this? And should I move out of Brittrex for future?

Thanks in advance.

No, this is normal. Both coinbase and bittrex are exchanges, which for their own security, and convenience for themselves and their users, offer no access to your private key. ( Which means that if they go down, your bitcoins will go down with them, you actually don't control/own your bitcoins if you store them there.

You will either need to use a software wallet, http://electrum.org , hardware wallet, such as a trezor/ ledger nano S, or ( which i do not recommend), an online wallet, such as http://blockchain.info < It is still quite hard to get the private keys out of these web wallets, so i would recommend sticking to the other two options i gave.

If you don´t want to thrust a third party, there is no way at the moment.
You are always depending on the software vendor to not steal your $PASSWD $MONEY $SECRETS, or have to hope that the exchange of your choice doesn´t confict with any law or disapera for some other reasons.
But thats only intressting if you have a lot of coin vlaue.
Sometimes it´s good to be poor, I wonder how all theses coin millionaires handle that.

my $0.50

You clearly have no clue what you're talking about.

There's various multi-crypto currency wallets linked above,

Quote from:  mjglqw

which give you FULL control over your wallet, and where the so called "third party", who coded the wallet has no influence or power AT ALL, ( or access to your private keys).

If they go down, you should simply be able to export your private keys offline, and import them into a new wallet.
( In some cases they can't go down at all, see trezor & Nano for example. I actually think exodus can't go down either, unless all the nodes of every altcoin go down aswell.)
