Upgrade to the latest electrum version and then follow this guide:

First of all electrum is not a bank.

Second knowledge of the seed allows anyone to restore your wallet. The password is not required if you have the seed. Since your seed has been exposed on potentially insecure systems you have to create a new wallet with a new seed, send all your bitcoins to a receiving address in this new wallet and stop using your old wallet.

You can create a new wallet using the file menu > new/restore option. In future be mindful of which wallet you have open at any time. The window title bar should contain the wallet name. Don't go receiving bitcoins at your old wallet.

Finally you may be wondering what the password is for. The password is for encrypting the wallet file on your PC so that if some malicious person or program should get access to that they can't spend your bitcoins without knowing the password to decrypt the wallet file. The wallet file contains the seed and related meta data. If you have the seed then you don't need access to the wallet file.

Hash collisions are possible which is why I've said above that you should use the full key fingerprint. If you use a truncated fingerprint (hash) then the chances of a collision are very real. With the full fingerprint there is no chance at all.

you can download the key from the github repo too:

The full fingerprint is given below. It is not possible to substitute a fake key if you use the full fingerprint to fetch it using gpg:

I created a script that downloads, verifies and offers to install electrum for you:

what conflict are you talking about?

There are no agent IDs or conflicting transaction #s in bitcoin.

Yeah you should install a wallet app on your phone or download software for your PC. Web wallets are not safe. Custodial wallets at exchanges are also not safe.

Bitpay wallet is actually an app that you install on your phone or PC. It's good so go for it.

Don't use brainwallets. They are not safe either.

Click "save" on the receive tab and the "new" button will become enabled. Click new to get another address. Rinse and repeat.

You can also add a description before saving the address so that when you receive funds to that address the description will show up as the address label.

sorry but bringing in xpubs and stuff is confusing. also the guy you replied to had it wrong but you agreed with him. you can always restore a wallet with seed in electrum. the dev calls it the "electrum social contract"

See one post above:

OP please read about change on the bitcoin wiki:

https://en.bitcoin.it/Change

Put simply transactions often have change that has to be sent back to your wallet. For privacy purposes it is better to use separate change addresses. You should leave this option checked. If you leave it unchecked change will be sent back to the address where the input coins came from.

Knowledge of the private key allows anyone to spend bitcoins sent to the corresponding address. Bitcoinvanitygen knows your private key and in future if they like they can spend bitcoins sent to it! You should not use this private key and address that you got from them!

What kolloh is talking about is a process through which you can get someone else to generate a vanity address for you without them knowing your private key. You generate the private key on your own computer and then give this third party the public key. They use that to generate a vanity address for you and provide you with a secret that when combined with your private key generates the correct private key for the vanity address. Since they never had your private key and only your public key your funds are not at risk.

That won't work for 2fa wallets since they contain p2sh addresses and there are multiple private keys for those. Electrum only shows one.

BTW OP I was wrong in my earlier post about restoring 2fa wallets. I just did a test restore and you can actually choose to keep or disable 2fa in the restored wallet. So you have the choice.

When you restore a wallet using that seed it will cease to be a 2fa wallet. You won't need to enter any 2fa codes or have anything to do with trusted coin anymore.

Edit: I was wrong. You can actually choose to keep or disable 2fa at the time of wallet restoration.

Ignore what these other guys are saying. They are just confusing you. Read this:

https://bitcointalk.org/index.php?topic=100502.msg18902622#msg18902622

To send money from one wallet to another you simply send to one of the receiving address of the target wallet. So go to the receive tab of your electrum wallet and grab the address it gives you there. Put that into multibit and send your bitcoins there. You don't have to muck about with private keys!

Don't scare him needlessly! There is nothing to be scared about. Electrum strives to maintain backward compatibility with all past seed formats so all he can simply backup the seed words and that is enough.

That was version 2.0 which was released in March 2015 which is well before the OP says he created his wallet.

Electrum supports two technologies for increasing fees for a transaction that has already been sent. RBF which does require that you mark the transaction as replaceable when you originally sent it. And Child pays for parent (CPFP) which only requires that you control one or more receiving addresses. The OP can use CPFP to bump the fee because it's very likely the transaction generates change and he controls the change address.
