First: I would recommend you always keep your wallet.dat for yourself. Don't give it to a untrusted, or dont even give it to a trusted member if the value on the wallet is high enough.
You could write a small script (e.g. python) to generate passwords with small mistake from the password you wrote down.
Then you could just go and let a script test all those combination until it works.

You dont have to worry about the Key Reinstallation AttaCK (KRACK).
This vulnerability gives attacker the possibility of reusing keys gathered in Handshake. This can be used to decrypt WiFi Traffic. This is not an exploit which allows to compromise a Network. There is no was of finding Out the WLan passwords or whatever.
Traffic should be encrypted with TLS (https) to not b vulnerable to an focused attack.
In Addition to that your priv key does never leave your PC. Only your Transaction will be broadcasted.
If you want to make sure noone recognizes your transaction you should always Connect via https to Push tx's.

Its not like trojans on the internet are waiting for hosts to come online to run at them. You need to actively download (and execute) malware.
There are only few exceptions where worms automatically make use of exploits and distributes very fast.
To test such wallets you could create a virtual network device which simulates the internet. After capturing packages you could see and control how the wallet tries to communicate with the internet.
Or you just go on github and read the open source code (i personally would not store coins on a closed source (and non tested) application.

To be able to access your Bitcoin and Bitcoin cash you only need your private keys / wallet.dat / recovery seed and 2 wallets (1 for BTC, 1 for BCH).
Now import the private keys into BTC respectively into the BCH client.
Further you should move your funds onto a "seperate address". It is not recomended to have the same private keys for your BTC and BCH.
The best would be to create new BTC/BCH wallets, then send your BTC / BCH to these new created addresses (you can achieve that by importing those priv keys in front of that).

Actuall you don't really need a SSD to run the Core client. But 700 kb of reading is very very slow. You should check your Hard drive.
It may be about to die. A standard HDD should easily be able to guarantee a read/write speed of 20++ mb/s without making your system slow.
I would recommend to download a HDD checking tool and read out your S.M.A.R.T values (https://en.wikipedia.org/wiki/S.M.A.R.T.).

And if your HDD is fine.. you could just wait until it synced 1 time (taking long time) but afterwards you wont have to wait that long to be up to date.
Im not a fan of SSHD. I dont like the concept. I would stay with HDD (at least one which has normal read/write speed)

There are several options you can get that transaction through afterwards.
You could either use a free TX accelaration service (you can find a few in the service section here; i think one is https://confirmtx.com).
But i think those are only free for transactoin up to ~500 byte (not sure about exact amount).
But you also could to try child pays for parent (cpfp), where you "double spend" a transaction with higher fee, which will replace your old transaction.
If you want a guide on how to achieve that, you can go here: https://bitcointalk.org/index.php?topic=1118563.0
But next time better include a proper fee for your tx to get accepted. You can use https://bitcoinfees.21.co/ to see how big the fee has to be.

To start off with, i would never store my bitcoins in a closed source wallet. You can't be sure wheter there is a backdoor or a security flaw which could allow an attacker to steal all your coins.
Yes you can export your private keys, you have to open


Afterwards you can import those private keys into electrum. But i still would recommend to send them to a new wallet generated with electrum.
Rather pay 4$ fee than having your coins stolen because of an exploit inside exodus. I did not found any certified application penetration tests on exodus.
But you also can create a wallet with a new seed and then add those private keys of exodus into electrum to be able to send "within electrum wallet" with adjustable fee.

You should definetly store your Bitcoins on a wallet which you have full control over.
I would not recommend to use an online wallet. Thats the only way to ensure you will own both coins after the fork.
Once the fork appears there are 2 coins which share the same block history (until "fork-block").
This means for every BTC you own, "you will get" one forked coin (simply by still owning the private key which has value at the time of the fork).
But there is no guarantee for you to get your forked coin from web wallet provider.
Electrum is a nice light weight wallet (does not download full blockchain).

You can take precautions to that not happening.
If you split your 1X and 2X coins onto 2 different(!) wallets/addresses you are fine.
No replay protection can only be exploited if those 1X and 2X coins are lying on the "same" address (to be exactly: on the same private/public key pair; since it can't be the same address when its on another network).
And as long (after the fork) you didn't send any coins, there is no Transaction which could be replayed on the other chain.

Properly is the keyword.
Truecrypt already had massive security issues regarding encryption. As far as i know devs made mistakes when using/overwriting RAM.
Veracrypt may not have this issue.. but i wouldn't call it 100% safe.
I did not know you can encrypt files with kpass yet. Thought it was a password manager only.

Using linux is always a good Idea. About 96%+ of Malware is written for Windows.
If you are using linux, do keep your pc offline almost all the time (you also should not plug in any "non-trustworthy" usb-devices anymore), keep it up to date (best approach would be to download linux update on another online-machine, then copy it via local network onto your wallet-pc, verify it there, then install it), you should be quite fine with your setup.
Assumed the wallets you use do not contain any backdoors.
I'd recommend a Hardware wallet (e.g. trezor/ledger) for your Bitcoins and (most common) Altcoins. Its more secured and easier to handle.


Well, its possible to download updates on another machine, copy, verify and install them.
And most linux distributions are not contacting 100 web services and creating 600 http requests before the OS is ready to start internet explorer 

Actually you can sign a message with ledger wallet.
You have to go into the options menu. There is a option to sign messages. Then you can choose one of your X addresses in your ledger wallet and paste text to sign.

As long as you still have your seed everything is fine. Clear your electrum wallet and try to reinitilaize it with your seed.
But as mentioned.. this is not necessary (and not recommended because of security concerns!!) because you can sign messages with ledger wallets..

The Use of a Hardware wallet is to have your coins secured and private keys encrypted without them losing your ledger.
If you use the same seed in electrum you are supposed to a lot of attacks and your HW wallet is kind of.. useless.

Trump (with his massive stupidity) if hes going to launch all nuclear bombs to destroy the world.

I'd say trust is extremely important for Bitcoin. If a hash collision will be found or big security issues gets public, BTC will fall within minutes.
If miningcenter are getting bigger and only a few miner own 50%+ of hashing power this could get risky to still use BTC. This also probably would dump the price.
Another factor would be if governments (not just 1 country, majority of countries) are going to ban BTC. This will not destroy BTC but price would drop extremely.
Thats all scenarios i can imagine. Maybe, of course, if internet/electricity goes down.

You could use your old PC as Wallet for any coins. Its important to keep it up-to-date.
If you are going to store a lot of alt coins, you should verify each wallet to be sure there is no backdoor/trojan.
I would recommend to build it air gapped (no internet connection at all - not even for transactions).

In case of performing a transaction you would have to do the following:

• boot Wallet-PC
• sign Transaction
• copy/print raw transaction
• shut down Wallet-PC
• paste TX onto your main PC
• push TX to Network (either directly from your node (if you are running a full node) or via online service (e.g. https://blockchain.info/pushtx)

If your wallet-pc is clean and has no internet connection i can't imagine an attacking scenario which would lead to a loss of your BTC's. (Of course dont let shady people boot your wallet-pc )

Actually, bitcoin already is "new money". And i also think BTC will get more widely adopted than its yet.
But i doubt if BTC is really going to replace FIAT. If the growth of BTC won't cut down it will definetly be accepted in more online shops / offline stores.
I think governments/banks are going to create their own cryptocurrency on blockchain technology (probably not decentralized).
Banks definetly want Paper money to be replaced by something "more controllable".
It may first be from paper money to credit cards only, then to cryptocurrency. 

80$ Transaction fee? No way.
How big is your transaction ? Did you make an error with decimals?

The only way i could imagine the TX fee would be that high, is if you had a massive amount of input addresses, containing a very small amount.

Unfortunately there is no other way of moving coins from paperwallet to ledger.
Ledger creates a HD Wallet for you. Addresses are being created with increasing counter.
There is no way to import a private key and add it to the wallet (and thats good for security and safety!).

Like the post above me mentioned, this is not possible (decentralized).
Even if it was possible.. this would probably destroy the whole Network.
1 Idiot with 1 BTC could send 50.000.000 Transactions (1 Satoshi TX + 1 Satoshi Fee).

And since Bitcoin would be "fair" - with your idea - there would be 50.000.000 TX in mempool.
Currently there are 55.000 TX's in mempool.

So when the next block would be mined, 99,89% (50.000.000 / 50.055.000) of all TX confirmed would be spam TX's - on average.
And since Attacker would be sending TX's to his own Wallet.. this Attack would cost 0.5 BTC (fees) and would make Bitcoin unusable.

Theoretically selling is as easy as buying.
You can sell the same way you bought your Coins. Either via marketplace (e.g. localbitcoins), currency exchanges (e.g. kraken), here in currency exchange section or Offline while meeting the person you want to trade with. After sending your coins to an exchange (for example) you can convert them to your FIAT currency and then cash out to a bank account.
But you have to be careful. You may need to pay taxes for your winnings of bitcoins as a investment, depending in which country you live.
And you also have cautious when meeting someone to trade with. There are a lot of people who rob people and force them to send all their coins to the scammer.
If you sell BTC make sure to not take paypal (or any other reversible payment gateway) - so you don't get scammed and lose your coins within seconds.

Banks might be scared of BTC a bit. But this shouln't be such a big problem with governments on their side which can regulate/forbid BTC in almost no time.
The real interesting part for Banks is the Blockchain-technology. And Banks will (for sure) switch to Blockchain technology.
But wheter this will be decentralized or not.. can't say today. Probably they will create their own crypto currency with a "centralized blockchain".
Paper money is not what banks want to deal with. In addition to that, smart contracts are getting more and more interesting since you can handle loans/interest without the need of a person who is controlling if everything works as intended.

Bitcoin is pretty strong compared to others cryptos.
Bitcoin has a market cap of 93 billion $, ETH (2nd highes market cap) = 31 billion $.
Those 2 coins, together, represent more than 90% of cryptocoins (in terms of market cap).
With Bitcoin leading this statistic, you can be pretty sure Bitcoin is "quite strong" compared to other cryptocurrencies.
