What are the most reliable/trustworthy tools for creating offline text-based keypairs which do not involve javascript/browser tools, Electrum, or tools that require a file to be stored (e.g. Bitcoin Core's wallet.dat)? Thanks

I am looking for tools that will give me a public address to which I can send funds along with a text-based private key by which I can sweep the funds later (it doesn't matter if this is a string of mixed up characters or a passphrase of mixed up words). A Linux command line tool would be ideal. I would like to avoid:
  1. Javascript : I've read that JS tools are known to occasionally create invalid keypairs.
  2. Electrum : I've read that Electrum does not follow all bitcoin standards making funds hard to retrieve if support for Electrum ceases.
  3. Data files : I would like to be able to access the funds using text only, no stored files.
Thank you for any advice you can provide.

Are Bitcoin Core wallet.dat files compatible between OSX, Windows, and Linux?

Like if I get rid of a windows PC, but want to build a linux box - can I use the same wallet file?

What is the best wallet to put the Bitcoin Core Wallet .dat file into to 'see' the SBTC [ after sending the Bitcoin to a new wallet for safety first,of course] But is there an SBTC wallet released yet for bitcoin core users like me.

How To Reclaim BCH From Existing Bitcoin Core Wallet.dat Files

I spent the last several hours trying to find out how to get BCH from a Bitcoin Core wallet.dat file that I had sitting around for a few years. After parsing a lot of information online, I finally figured out a process that works. Since there wasn't an updated and succinct summary elsewhere, I thought I would post one.
You Will Need:
Instructions
These commands unlock your wallet for 600 seconds and creates a text file listing all your addresses and private keys in ...\Your_Bitcoin_Directory\BitcoinDumpWalletdump.txt
Isn't it just all still in the address it was sent to, less whatever I've spent? Only if you've never spent anything from those addresses. The bitcoin core client always spends 100% of the bitcoin in an address when completing a transaction, sending any "change" to a new address. This new address is not normally visible to the user, which is why I needed to dump the wallet and figure out the actual addresses my BTC/BCH was living in via blockchain.info, rather than just getting a particular private key for my receipt-address.
Other Notes
You could shortcut this process by downloading the bitcoin abc full-node client for Bitcoin Cash and loading your wallet.dat file into there. Unfortunately, on Windows, bitcoin and bitcoin cash nodes do not play nice together, so it would only let me open one at a time. I was also concerned about corrupting my wallet file for bitcoin and/or having to re-download the blockchain, so I wanted a different client for BCH.
Jaxx might also work as a BCH wallet, but the latest version doesn't support import of private keys, so I went with Exodus. I'm pretty happy with it!

Which security scenario is safest and why?

Hi All, wanted your opinions on which of the following is LEAST secure for storing your bitcoin and why.
A) TrezoKeepkey/Ledger hardware wallet with two copies of seed phrase engraved in metal and stored in safe deposit boxes in different banks
B) Paper wallet with private key split into 4 parts, engraved in metal and stored in 4 separate locations
C) Bitcoin Core wallet.dat file removed from implementation of Core and saved on six separate USB devises, stored in three different locations (duplicates in case of corruption/deterioration of one)
D) Coinbase... ok, ok, this ones just a joke :)

Thanks for your thoughts!

Edit: Maybe I should ask first, which is LEAST secure..

Long time BTC hodler needs help with claiming fork airdrops

I haven't touch my BTC for a long time but due to tax reasons (not an US citizen) it's a good time for me to claim and sell the different air drops/forks that are available before end of December this year, especially BCH and BSV. Yes, I know I'm late to the game but my BTC holdings are a long bet and I don't easily risk or touch them.
I've read a lot of threads and guides on BCH/BSV splitting but haven't found all answers I need, so here it goes. Any help is appreciated!
Some background info: MY BTC UTXOs are from 2013 and early 2017 and are in a Bitcoin Core 0.19.0.1 wallet.dat (Windows). For preparation I have just moved all my UTXO's to a completely new Bitcoin Core wallet.dat and made several backups of the two wallet.dat files both before and after I moved the UTXOs.

Question 1) Running Bitcoin ABC wallet 0.20.7 with the original BTC wallet.dat displays the correct number of BCH available for me to transfer where i want. Can I safely transfer all those UTXOs from Bitcoin ABC wallet 0.20.7 to my Exchange (Bittrex) without risking the transaction to replay on the BSV chain?

Question 2) If the answer to question 1 above is no - From what I understand from all guides and other threads I've read (although some of them are old) I should import the private keys from Bitcoin ABC wallet in to Electron Cash.
I read that the Electron Cash 3.3.4CS is no longer recommended for splitting and latest version only supports BCH. So my guess is I should use Electron Cash 4.0.12 from https://electroncash.org/ and Electrum SV 1.2.5 from https://electrumsv.io ? Is that correct?
Is the following a correct procedure? (or is there an simpleother method?)
a. Move all BTC UTXOs in Bitcoin Core wallet to a new wallet.dat DONE
b. Import old BTC wallet.dat to Bitcoin ABC wallet. (Full amount of BCH are displayed) DONE
c. dumpprivatekey command in Bitcoin ABC wallet
d. Import the private key in to Electron Cash 4.0.12
e. Buy some BCH on Bittrex and send it to the Electron Cash address
f. Send entire BCH to Bittrex (and sell for BTC....)
g. Import the private key in to Electrum SV 1.2.5
h. Send entire BSV to Bittrex (and sell for BTC....)

Question 3) Are there any other forks worth claiming (for immediately selling) and are fairly easy to self extract non custodial? I hold exchange accounts at Bittrex and Poloniex so the forks should be available to sell there. I do not want to go through the hassle and privacy risks of registering yet another KYC account unless the fork reward is substantial.
Cheers!

wallet.dat in Bitcoin Core 0.20 ver not found in AppData Windows 10

Hi everyone,
In the latest version of Bitcoin Core ver. 0.20 there seems to be no Bitcoin folder in the C:\Users\ABC\AppData\Roaming - hence wallet.dat is not stored in there.

Does anyone have experience with this and knows where it's now stored please?
I would appreciate your sharing and thanks a lot.
Cheers,
TN

[Help!] Transfer funds without syncing Bitcoin Core

Hello guys,
Here is what happened. I have done a small freelancing work, and the guy asked whether to pay in Bitcoins. Having never owned Bitcoins, I said YES.
I quickly fired up to bitcoin.org and there I was asked to choose a wallet. Selected the first entry in the list of things, which is Bitcoin Core ,downloaded and installed.
I then created an address to receive funds, and sent it across. Which I was confirmed that went successfully.
https://blockchain.info/address/39UM5DMztcEmP2RoBiHJfArhuVuSv3Ndcj
Then I switched back to Bitcoin Core, to check if the transaction really went through; here I am seeing it is downloading a HUGE set of files. Having only a capped amount of data, I quickly disabled syncing. 150GB is a half a year worth of data for me.
To obtain the funds without syncing, I have tried few things with no luck yet;
Is there anyone who can point me in the right direction?
Thanks.
----------------------------------------------------------------------------
Update: SOLVED!
As u/Hodlini , u/MrRGnome and u/BobAlison suggested, what was missing was the "p2wpkh-p2sh:" prefix when importing to Electrum.
Since I have entered my private key in many places while figuring things out, I have moved funds to a separate wallet; just to be safe. :)
Thanks all for pointing me in the right direction!

My conversion failed and I might have lost 20 BCH somehow

I bought BTC a long time ago and it's lived in a Bitcoin Core wallet.dat file. My read on how to fork properly was to wait until the fork happened, then transfer all my original BTC to a new wallet (which I did by sending a handful of transactions to an Electrum wallet), then after the post-fork BTC was safely associated with a new keypair in a different wallet, and Bitcoin Core showed 0 BTC, that I could use the private keys in that wallet and "Sweep" them with the BCH Electron Wallet. I had 5 Bitcoin Core private keys and swept each into Electron Client. Only one of the Bitcoin Core private keys had anything on it, 50 mBCH, which means I'm missing the VAST majority of my BCH somehow.
I'm currently building a new isolated VM to install Bitcoin ABC on, but the block chain will take about a day to sync, so I'm kind of frantic about there being a missing ~$30k worth of BCH that may or may not still exist while I wait to import an old pre-fork copy of the Bitcoin Core wallet.dat.
Does anyone have any similar experience with moving forward on the fork and running into this problem?
As you can imagine I'm kind of distraught right now until I figure out what the heck happened.
Thanks!

On the fence with the Nano S because...

A friend of mine submitted a very detail post and didn't get any response, but I see newer topics with replies from the CTO and CEO on here. Perhaps it's because his account was new. Still, if this kind of radio silence on issues is the norm, I'll stay away from Ledger. If not, please help! His post is mirrored below for your convenience.
Thanks for beating this dead horse with me ..... I have a Ledger Nano S with a segwit BTC address created that has had post-fork(s) BTC sent to and from it. No other addresses have been transacted to/from.
I've got some old, pre-fork(s) BTC sitting in two addresses in one wallet.dat file on an old non-networked machine. I've read the posts about importing the private keys into electrum and then sending from there, as well as this lengthy post using Insight and transaction id to create and broadcast a raw transaction. I've also read numerous doc on the ledger website and here on how to split off the Bitcoin Cash and Gold. However,...I haven't come across the post that weaves all of these together for my particular scenario, nor have I seen any of the posts really touch on the 'legacy' option for the Ledger Nano S and am wondering if this is a use case for it?
Goals:
  1. Move all pre-forked BTC to Ledger Nano S
  2. Split Bitcoin Cash from BTC
  3. Split Bitcoin Gold from BTC
Unknowns:
Expected Results (all on the Ledger Nano S):
Thanks!

Claiming BTG from fork confusion

Hi, I have transferred my bitcoin from it's current wallet to a new one (this transaction is still unconfirmed) then placed my current bitcoin core wallet.dat in the place of the bitcoin gold wallet.dat. The strange thing is it is showing the unconfirmed new transaction and that the BTG ballance will be 0 once this is complete. When I claimed my bitcoin cash I followed the same procedure however it looks as though the same will not happen as the bitcoin gold is transferring away form the original wallet.dat. hopefully this makes sense. Any thoughts?

Out of the loop - Hardware wallet question

I used to mine Dogcoin way back in 2013/2014. I had no real idea what I was doing but I made a few hundred off of it. Fast forward to today, I was looking through my backups as I recalled having some BTC in a Bitcoin Core wallet.dat file. Low and behold, I now have 0.06BTC in my possession.
Since I had no idea I had this, I'm not too bothered about cashing out and it'd be fun to ride the wave so I'm looking into hardware wallets to keep the currency safe.
The Ledger HW.1 seems perfect for me but the cheapest I can find it is £36.99 which seems quite expensive for something that started at £15 (no longer available from Leger). Also, there's no telling how long it'll remain supported.
My next best option is a Nano S but it seems a bit unnecessary at £70.
Are there any other options? I don't trust myself with a paper wallet so would like to avoid that.
*Thanks for the replies everyone, I've decided to get the Nano S as I've been looking to get back into BTC for a while and I'll probably end up with more.

Found an old wallet backup

Years ago I used to dabble in mining bitcoins on a linux box. At the time I didn't really take it seriously, and don't recall any of the details about my wallet. Today, I found a file stored on a drive "bitcoin_wallet_backup". No file extension and with a file date of Apr 2013. When I open the thing in a text editor, it's just encrypted gobbledygook.
I have no idea what I would have been using for wallet software at the time. Any idea what I can do to restore this backup?
UPDATE: renamed file to wallet.dat, replaced Bitcoin Core's wallet.dat with it. 0.05 BTC (WHOOHOO!)

'''
I synched the Bitcoin Cash chain using the BitcoinABC Core client.
Can I use my Bitcoin Core wallet.dat, load it in the BitcoinABC wallet and send the bitcoins to an exchange without any risk of loss to the bitcoins on the other chain right?
This will not be possible with the 2x fork? Right?
