Has anyone else seem this problem and is there a solution?
It has been mentioned before on this forum. The solution is to create a new wallet and move your bitcoins to it. Or, does Electrum have a limit on the transactions/address it can handle?
not an arbitrary limit or anything hardcoded in the code. it's just that it gets slow when you have lots of addresses and/or transactions. |

you can't do what you are trying to do with electrum. offline signing with imported private keys is not going to work. at least not via the GUI

electrum has a json rpc interface but it isn't well documented. i think it's mostly the commands you see when you type electrum help except you send them to the electrum daemon. and yes electrum help doesn't work on windows.

just to make this really simple....and clear....
[1] Does Electrum now support the new 3 prefix addresses? [NOT THE MULTISIG]
[2] if yes how do you use it?
[3] if yes and I import an old wallet, that uses 1 prefix by any method (priv key, seed, wallet etc), will this still be usable in the new version
when and if Electrum does support this how will [2], and [3] be handled.
I can see a lot of people will just upgrade then send then something untoward happens.
Oh you're asking about segwit addresses? Is that correct? Electrum's support for segwit is still a work in progress. When it is completed you will need to create a new wallet to take advantage of it. Create a new wallet and send all your bitcoins to an address in it. Electrum strives to maintain backward compatibility especially with old seed backups so you should have no problem using your current wallet in future electrum versions. |

if you decide to create a vm then virtualbox is free and open source software for that.

no you assumed wrong. electron cash may have malware in it and that is why the recommendation is to use a separate computer. when you install malware on your computer it takes over the entire pc. Doesn't matter which electrum wallet you have your coins in. if that new wallet is on the same pc then it can be affected by the malware too.
that's why they recommend you install it on a separate machine or a isolate it in a virtual machine.

the method outlined on the electrum website actually tells you to install electron cash on a separate machine entirely: https://electrum.org/bcc2.txtalternatively you can install it on a virtual machine on the same computer. note that this forum is not for electron cash. it is for bitcoin electrum only |

that 0.01 is likely going to trusted coin which is the co-signer of your 2fa wallet. you were informed of the charges of this type of wallet when you originally created it.
idk why it sent just 0.3 to exodus when you wanted to send 0.4 something.

this forum isn't even for electron cash... |
|
|

you could do it if you restored your wallet from seed in electron cash. but first move your btc to a new btc wallet using. also install electron cash in a VM or separate machine. do read this as well https://electrum.org/bcc2.txt |

FYI the amount you enter in the receive tab does not affect how much someone can send you. It's only for your own reference. The same goes for the description. It is not shared with anyone.

The wallet you have is a 2fa wallet. If you don't have the 2fa code then you can do a restore using the seed mnemonic. Do you have the seed mnemonic of your wallet?
i don't have seed i just download the wallet from electrum.org and start using it i just enter a password ! please help me what to do ? that's not how the wallet creation process works. either you or somebody else with access to your computer created the 2fa wallet. if you don't have the seed or the 2fa code then your money is lost. there is nothing anyone can do to help. |

Im using electrum 2.8.3.
Does this need to be downloaded before the bitcoin fork?
you don't have to do it before the fork but it's a good idea to keep up with updates because they include new features and bug fixes. |

maybe it's downloading the block headers but those are 37MB total so they shouldn't generate a lot of disk activity. given the other things you said like using a third party repo and the mismatch in the version numbers I would be advice caution. did you just install malware?
|

to confirm whether you have a 2fa wallet or not just look at your electrum window title. it should say "2fa" or "2 factor authentication" there.

When you set a password the secrets in your wallet file are always encrypted. Do you understand? Setting a password always means encryption. The only difference with that "Encrypt wallet file" checkbox is that you can't even view your wallet's transactions and balances until you enter a password to decrypt the file. Why would you want that? Because some people receive money to a wallet without knowing the password or seed of it so they end up losing their money that way. To prevent scenarios like that the developer ThomasV created this whole wallet file encryption option so you can't even view your wallet until you enter the password.
I had to read through your post a couple of times, but I think I see what you mean. If you set encrypt, Electrum will then "challenge" you to enter a password before any transactions or addresses are visible on the wallet, to make sure you know the password and can later send bitcoin you received. So "encryption" option is not just for scrambling all the wallet data in the file to prevent others from viewing, it's making sure you don't receive bitcoin, and later are stuck unable to re-transmit them, because you didn't know the password. Yes that's for full wallet encryption. However just setting a password and choosing not to encrypt the wallet file will still encrypt your wallet secrets i.e. the seed + any imported private keys. |

do you have a firewall or antivirus software running on your computer?

Wow, amazing response HCP, 5 stars.
A couple of follow-up questions.
Does the bump up in security from password, to password+encrypted come for free, or do we have to do extra work to get it (an extra password to remember?)
What kind of extra percentage (approximate) security would you say encryption gives over just password? 10%, 30%, negligible, etc...
I mean if someone got hold of my computer, and my password (maybe brute forced while computer is at shop being repaired) would the fact that the entire file is encrypted offer any more protection if some evil computer repairman has figured out my password? Don't really want to just press encrypt until I know what this offers, and what's expected of me to maintain things this way. Thanks.
