The BTC has now moved and Kraken didn't hold it the full 24 hrs since I changed my password so that is sorted. I contacted my credit card provider about the authenticator app charge which is pending after my 3 day free trial. They have put a block on there.
The problem seems to be that I changed my password, then added a new withdrawal address. There is a 24 hour hold on new addresses created after a password change, so I expect to see my BTC going where it's supposed to be going after the 24 hrs have passed 
. Thanks everyone.
I must add I found the 2FA a pain. 2 different authentication apps that I attempted to use offered me a 3 day free trial and my credit card number flashed up so I hope I'm not signed up for these as I can't see anywhere to unsubscribe.

I can confirm that their customer service is fantastic. I had to hold maybe 15 minutes this time before I spoke to someone but they have always been very helpful and solved every issue I have had. Having said that after confirming the withdrawal address and proceeding with another withdrawal, it still hasn't shown up on the blockchain and over the years every transaction I've made always appeared immediately even though it may have taken taken a while to confirm. I will call them back if it doesn't confirm.

Thanks for all your replies. I think I have worked out what the problem is. I received an email for me to verify the new withdrawal address but I only just saw the email and the link expired after 60 mins so I can't verify it now. Currently on the phone with them here, hopefully they will be able to sort it for me.
I deposited BTC to my Kraken account from a cold storage wallet. I intended to only send to Kraken what I wanted to sell but mistakingly sent all that was in the wallet. I have been trying to withdraw back what I didn't sell. I tried a small amount first to make sure it would work alright as I had never done this before so I sent 0.00099 btc to my original non-kraken wallet, but now an hour later it is still not showing on the blockchain....I know it may not have confirmed in the hour but surely it should have appeared immediately as a transaction on the blockchain? Anyone have any idea what could be wrong? TIA.
I got hacked on Feb 12
The wallets i created using BitAddress.org were not hacked
But the ones from https://segwitadress.org/ were
Both had passwords
Not sure , if the hacker left BitAddress alone because they contain 0.01 Btc only
But my ETH paper wallets were also hacked as well as a multi sig wallet I created with Electrum
I don’t trust paper wallets now

Did your create the Bitaddress paper wallets on an air-gapped computer?
I would not use paper wallets anymore, this is outdated method for saving your bitcoin.
It is better to save seed words on paper, from that you can generate multiple addresses later, add passphrase, and you can export it as QR code if you want.
I like paper wallets because of how easy it is to add heavy encryption (BIP38). I'm still working on a project to use that on seed words (BIP39).It is better to save seed words on paper, from that you can generate multiple addresses later, add passphrase, and you can export it as QR code if you want.
I like paper wallets too.
I hope writing everything down with a pen and paper would solve that problem?
If you want to be able to write things down without making a mistake then it is very difficult to do with with a WIF private key that is a long random alphanumerical characters. It is a lot easier to write down words, which you can do if you use a deterministic wallet like Electrum that generates a mnemonic (12 words) that are easier to write down. That way you have the benefit of also being able to generate more than one address from those words which comes in handy in the future when you want to spend your coins (avoids address reuse).thank you

Thank you. I presume that even if there was a virus or something on the Chromebook from the one and only time it was used, it wouldn't be able to steal my private keys if I go offline to create them and am never online again on that device?It depends. It'll only stop virus which works by sending private key or other data to certain server using internet. You're still vulnerable to clipboard virus, which replace Bitcoin address when you perform copy and paste.

So my question is.... is the Silk browser that Amazon Fire uses OK for this purpose? (just wondering because I know somebody mentioned IE8 not being suitable.
That "IE8" was from 2011 to 2009, as long as your Silk Browser is updated with a newer Javascript support, it'll work (and it did).For the record, if the browser or device isn't supported by bitaddress like Window7's Internet Explorer 8, the tool will not be able to create a paper wallet entirely.
Amazon Fire was a bit of a waste though since you can't now use it online.
You could've dedicated an offline machine without an internal drive, then use an "amnesiac" OS that's installed on a flash drive like 'TailsOS' to launch bitaddress offline.
You can destroy that Flash Drive later if you want since it's cheap, although everything you did while it was active was on your RAM (will not linger after a few seconds once depowered)
I made them by entering a very long string of numbers and letters in the BrainWallet box.....not that they are a brain wallet - I will never remember the numbers/figures, but that is the way I have made all my addresses over the past 11 yrs & it has worked for me.
Yeah, that was only for additional entropy for "seedTime" and the majority of the entropy is still generated with its SecureRandom function.Thank you. TailsOS, etc is not something I am familiar with.
I have another question, I have a Chromebook which was only ever connected to the internet once (actually I tried to install Electrum on it but was unable to as it doesn't have Windows). That's the only time it was ever online. If I downloaded bitaddress to it and then went offline (forever!), would it be safe to make more addresses on it? Thanks.
IMO it's safe enough. BTW, you can run Linux application on Chromebook. So you could Electrum AppImage file and then run it on your ChromeBook, assuming your chromebook doesn't use ARM chip.

From quick google search, Silk browser is based on Chromium, where Google Chrome is also based on Chromium. So theoretically there shouldn't be any problem.

Probably you read an old case/accusation? I haven't read any accusation against paper wallet anymore.
They have an ANN thread in this forum, there's no complain on the thread [ANN] bitaddress.org Safe JavaScript Bitcoin address/private key
Here's the tips if you want to run safely bitaddress on an air gapped device https://security.stackexchange.com/questions/274683/safe-usage-of-bitaddress-org

So I went ahead and made some addresses with bitaddress. I did so on an Amazon Fire tablet that was never connected to the internet before and never will be again. However, since then I have been wondering if they are accurate - it did not allow me to generate them by moving the mouse around to use the green dots (I didn't want to do that anyway). I made them by entering a very long string of numbers and letters in the BrainWallet box.....not that they are a brain wallet - I will never remember the numbers/figures, but that is the way I have made all my addresses over the past 11 yrs & it has worked for me. So my question is.... is the Silk browser that Amazon Fire uses OK for this purpose? (just wondering because I know somebody mentioned IE8 not being suitable. Thanks.
As regards bitaddress I read this in a thread mentioned above 'the zip version in github is :v3.3.0 remove support for IE8'....I don't even know what this means but the version showing now is 3.3.0.......will I have any problems?
IE8 refers to browser called "Internet Explorer" major version 8, which available for Windows XP to Windows 7. Meanwhile v3.3.0 refers to version of the bitaddress. So you will not face problem if you don't use that browser.
I didn't have any problems and hope the addresses made are OK. I have another question, I have a Chromebook which was only ever connected to the internet once (actually I tried to install Electrum on it but was unable to as it doesn't have Windows). That's the only time it was ever online. If I downloaded bitaddress to it and then went offline (forever!), would it be safe to make more addresses on it? Thanks.

Yes, I 100% trust this friend. She knows absolutely nothing about bitcoin; I set it up for her years ago and this is the first time that we have attempted to sell anything. I will get back to the person that asked what the first digit of the key is. I don't have them, she does and we will meet again later this week and try to solve the problem. Thanks in the meantime.
I was about to use Bitaddress.org again tonight but read where somebody said 2 of the addresses it had generated for them had the same private key so obviously there was a major problem to put it mildly! I am not good with technology
You don't need to be technical experts or good with technology to use a Bitcoin wallet software.If you are able to use Internet, desktop computer, laptop, smart phone, I am sure you can install and use a good Bitcoin wallet software.
Now what is a good Bitcoin wallet software?
Two things:
- Non custodial: so you own mnemonic seed or private key.
- Open source: the software is reproducible from its source code.
You can use Electrum wallet on computer or mobile device, it's light as it is a SPV wallet and does not require too big disk space.

I will get round to answering everybody but for now, as regards Electrum, IF I opted for it, to guarantee safety wouldn't t be best (just like with bitaddress) to do it on a computer which never has been used for the internet before and which never will be connected to it again in the future?
I was about to use Bitaddress.org again tonight but read where somebody said 2 of the addresses it had generated for them had the same private key so obviously there was a major problem to put it mildly! I am not good with technology and the simplicity of bitaddress really appeals, combined with the fact that I have used it many times before but it worries me that it might not be 100% reliable even if I generate the keys offline on an air-gapped device (which is the way I have always done it). Has anyone had any problems with it recently? (I know I asked about the Electrum wallet in a separate post but truthfully this is the one I am most comfortable with and would love to stick with it).
