First, understand that both Bitcoin and Bitcoin Cash can share the same address - that's why the transaction got confirmed in the first place. What happened is that you had X Bitcoins and X Bitcoin Cash in your wallet (the same amount in the same address). Both coins are there, but the difference is that you can only see and spend each of them with a compatible wallet for each coin.

In your case, you can only see and spend your Bitcoins with Electrum, and you can only see and spend your Bitcoin Cash with Electron Cash. You basically sent Bitcoins (and not Bitcoin Cash) from your Electrum wallet to your Electron Cash wallet.

Now you have:
1. The first wallet with Bitcoin Cash and no Bitcoins (since you sent the Bitcoins with Electrum to a different wallet, and the Bitcoin Cash is still there since you need Electron Cash to spend them);
2. Your new wallet (from Electron Cash) that has your Bitcoins and no Bitcoin Cash.

How to fix that:
1. Get the Bitcoin Cash wallet file - that you just created and you sent Bitcoins to - and open it with your Electrum. You will see your Bitcoins there.
2. Get your FIRST WALLET (the one you used to send the Bitcoins in the first place) and open it with you Electron Cash. You will see your Bitcoin Cash there.

Now just spend them as you like. I know that it may sound confusing, but I tried to explain the best way I could.

What is most likely to happens:

- Electrum will not support B2X officially.
- Your address will receive B2X since you own your private key.

But you won't be able to see or spend your B2X manually. For that, you will probably need to export your private keys to a B2X compatible wallet to spend them, and keep using Electrum for the legacy chain. It's the same as Bitcoin Cash, but if we don't get replay protection by the B2X side, your coins may be in risk while you send a transaction.

There is no transaction made when you just import your address in a different client. So yes, there won't be any fee when you do that.

But you will still need to pay a fee anyway when you want to spend your coins in the future. A quick "fix" for this, would be to sweep all your balance to yourself (or to a new address) with a lower fee (which should take a few days to confirm, so do it when you won't need to spend them), to consolidate all the inputs into one single output. Then, when you need to send a transaction with a higher fee for faster confirmation, it will be cheaper since there won't be that many inputs increasing the transaction size.

What happened:

So, a newbie just created a thread asking for reviews about his new Ethereum Mixer called "Dead-End Ethereum Mixer".

The minimum amount is 0.1 ETH ($30) and he is paying 0.5 ETH ($150) per valid review. The website doesn't even have a paid domain since it's just a free website created with Weebly. It's a static website that accepts anything in the "INPUT ETHEREUM ADDRESS" and "ETHEREUM FORWARD ADDRESS" fields (even if it's not a valid Ethereum address) and gives the same deposit address to every user and mixing session.

His thread is self-moderated, so my reply is probably going to be deleted when OP is back online.

They haven't released anything so far. They will probably release a statement in their blog[1] a few days before the fork just like they did with Bitcoin Cash and Bitcoin Gold.

I believe that they will support it, since they said that they were prepared for the potential BTU fork a few months ago[2].

Can someone tell me why there is a need for change addresses? Can't we just send the "change" of the transaction back to ourselves?

I use only one address to receive my signature campaign payments and if I have something like 0.05BTC and want to send 0.03BTC to my local exchange, the remaining 0.02BTC is always sent back to my address. Is there is any issue on doing this?

Only the second one (Segwit) is really a Segwit wallet, which is using the bech32 format, thus not recommended right now since most services don't support this format (address starting with bc1).

The first one (Standard) is a normal address.

I honestly think that it doesn't matter if you want to hold your coins in your phone or computer. Both are secure enought if you know how to secure your device.

It's actually pretty simple to have standard security for your devices.

PC = Use anti-virus, don't download everything from the internet. Better if you just hold your coins in a offline cold-storage wallet.
Android = Don't root your phone. If you do, don't download random apks from the internet and don't give them root permission.

If you want to hold multiple coins other than Bitcoin, use Exodus for PC or Coinomi for Android.

If you want to sell your coins, do it in Coinbase for real money, and not for the USDT scam.

Just like others already said, you can't really know if every USDT in the market is really backed by the dollar. They already got problems with their banks in the past, like all incoming international wires to Tether being blocked and refused by their Taiwanese banks[1]. Or how they just created $70 million USDT from nowhere[2]. So I wouldn't trust them.

For the fork, I would just use a legacy address to avoid any compatibility issues with other wallets. But if you don't care, and it's just planning to keep using and storing your coins in the long term, I would use a Segwit address (if you are not using Electrum, since they are only supporting the bech32 format, which isn't supported by any major service atm).

Are you using Electrum 3.0? There is a option in the first step "Import Bitcoin addresses or private keys".

Try to follow this guide with your Blockchain private key:

The website is safe. But for maximum security, you should download the source code yourself and run it locally while disconnected to the internet. Just download the code from their repo[1] and open the index.html file in your browser.

With Electrum, you can't. That's why they recommend you to create a standard wallet until the major services start supporting the bc1 format. If you want the format starting with 3, you will need to use another wallet - such as GreenAddress or Trezor.

Can you try installing "Visual C++ Redistributable for Visual Studio 2015" and running Electrum 3.0 again?
It may be a solution for this issue, but I can't test it because I can't replicate the error.

For face-to-face transactions, it's always better if you don't bring your wallet with you - to avoid someone trying to rob your coins. Instead you can:

1. download a watch-only wallet in your phone and import your address. Thus, you can only receive coins, and not spend.
2. print a QR code with your address.

The person selling you coins would need to have with him his wallet. So he should be able to scan your QR code from the paper or watch-only address and send you your coins.

I suggest you to use Mycelium, Electrum or Sentinel to import your Bitcoin address (not private-key).

They appear if you just for a tx with this kind of address and enable the advanced view. But you can't search or view the page of addresses with Bech32 format which is current used by Electrum 3.0;

I did some research and found that at least BTC.com and Smartbit.com.au can be used to look for addresses with the native Segwit format.

It's actually pretty simple.

1. Download Electron Cash[1] (an Electrum fork for Bitcoin Cash).
2. Open the same Electrum wallet that has the BCH with it.
3. You should be able to see and spend your BCH coins.

Yes. As long as you have your seed, you can recover your whole wallet - and consequently sign messages - whenever you want. That's the "heart" of your wallet.

I'm not sure how to fix that, but I found a reddit user who may be able to help you. JUST DON'T GIVE HIM YOUR PRIVATE KEY IF HE ASKS YOU TO!
