I can't find the official documentation regarding signing arbitrary messages with these addresses. Can anyone enlighten me?
Did electrum implement its own or an unofficial standard? Will this be supported by Core?

It is neither a bug nor an abandoned feature. It is just that we are still working on creating a more generalized signing scheme that lets people sign with things like P2SH addresses (e.g. sign with a multisig address). There is simply no standard yet for signing with such scripts or with Segwit.

Note that you don't actually sign with an address. You sign with a public-private keypair and your wallet interprets it as an address. Your wallet could just as easily interpret it as a segwit address. We are working on creating something that actually specifies the address type, and more generally, allows signing with scripts.

My understanding is that if I have my BTC in an Electrum wallet, I will be able to collect BTCP.

Is the Bitcoin Electrum wallet different?

Can I have both Electrum wallets simultaneously?

They can't even post a normal shared link that you must click to open/view?

Thank you my dear friend.
But after I Upload a few photos on iMGUR, how can I attached them to the forom?
Thanks

I'm signing my transactions offline, doing cold storage.

But I'm wondering how malware on an online computer could steel private keys from an Electrum hot wallet that is encrypted and password protected.

you should add some related links in front of each check. for example in front of BCH add the link to its website or bitcointalk announcement topic or both and also the explorer you used to fetch the balance (if you are using a explorer, if not explain how you are doing it).

[...] I like that good forum members can make money, especially when said forum members are in poorer countries and this is a major opportunity for them. I very much do not want to destroy the sig-ad/airdrop/bounty "industry". But I am not going to tolerate people posting garbage upon garbage. If the merit system completely fails and I can't think of anything else to replace it, then my next step will probably be to completely remove all ways for forum users to make money from posting (eg. removing signatures entirely).

Maybe there are ways for people who were making money by posting garbage on the forum to make money on other sites with easy bounties, etc. (For example, I don't know if they're actually any good, but https://bountyhive.io is currently advertising on the forum.) But people should use the forum to talk about these money-making ideas, not as a way of making money itself. Once you spend a lot of time here, you may be able to make some money here (which is great!), but you should consider this a far-off hope, not your primary objective.

BTW, if anyone has any ideas for simple things that these ex-nonsense-posters could usefully do to make money, I think that this'd be a good project right now. There are apparently quite a few people who were making money on the forum and could use guidance. Even though their past activities were not good for this forum, I doubt that they are useless in general.

I do t have an pc with webcam ... Thereis no other way to verify the account ? Smartphone does not work ?

I've never seen something like that before!! Thanks for sharing.
Just one question: what is the link source? How do you get it? Where did you see that?
This is an extraordinary strong attempt os pishing, and this website should be reported immediately, so, if you can, copy here the address in order to other users can check out what's going on there.

Again, thanks for sharing this.

It is going to be difficult for you to become a member if you post that kind of questions in the wrong place. One advise: read, learn, be patient. And make your comments where they belong.

yes i download i from electrum.org i try 3 installer windows from it . standalone . installer and signature all same give error python35.dll
i try again later with all av off . its include windows defender ?

to be able see total coin in my address should wait sync time finish ?

CMC is only a site which we get  very large info.

I don't think ads will do anything with our opinions as we see it's ad.  All CMC does about ads (if not Google ads) only taking money and showing ad. it's net their responsibility to investigate all ads and then share

Considering that the "Import" function no longer exists on Electrum.

I dumped the private key on Bitcoin Core from the address I received the BTC, then tried sweeping it into Electrum and got an error message. I created a new standard wallet on Electrum and cliked on Wallet>Private Keys>Import>Paste Address and Private Keys. Am I doing it all wrong? Should I use another address?

All I wanna do is avoid transaction fees. Is there a way to import the BTC from Bitcoin Core to Electrum without sending them to an address on Electrum?

How would a Portfolio Manager app that is not the exchange upon which you made the transaction be able to track the exact price you paid without you entering it manually? You're seeking a Portfolio Manager app that is fully integrated with all the exchanges you work with. This would be great, but this industry is way too young to have such integration.
