تقنيا الرصيد الذي ترسله للطرف الاخر يضاف الى رصيدك الخارجي remote balance.
طالما ان القناة ما زالت مفتوحة فرصيدك و رصيد الطرف المقابل يعتبر رصيد مشترك.

في المثال الذي طرحته مثلا الطرف المقابل لا يمكنه استعمال المبلغ الذي ارسلته اليه الا لاعادته او اعادة جزء منه اليك طالما ان القناة مفتوحة.
لكن عمليا كل طرف يمكن ان يكون متصل باكثر من طرف اخر و هنا يمكن ان نفهم لماذا سمي المبلغ الذي ارسلته مع المبلغ المتوفر اساسا للطرف الاخر بالرصيد الخارجي:

لنفترض انك فتحت قناة مع احمد و احمد فاتح قناة مع علي. اذا اراد علي ارسال مبلغ اليك فعليه الارسال لاحمد و احمد يقوم بالارسال اليك ليس مما ارسله اليه علي بل من رصيدك الخارجي (المبلغ الذي قام بايداعه عند فتح القناة معك اضافة للمبلغ الذي ارسلته اليه)

اسف على تداخل المعلومات لكن اتمنى ان تكون الصورة واضحة.

Yobit is one of the shadiest exchanges out there and there are many open scam accusations against them.
Even if you exchange their shitcoin for doge you will get aro~2$ worth of doge.

It looks like they are promoting their new scam shitcoin now (DLRS). Just to understand how shady they are and how far they would go to deceive their customers: when you visit their website you will see
dollars!! How deceiving is that!

I'm not sure about facebook but this is not going to help for twitter accounts.
AFAIK, campaign managers ask for the twitter handle and not the profile name to join their bounty campains. Unfortunately, you can't change your handle.
@notblox1 you are correct, you can change the handle from profile settings. I just tested it and it worked.
Sorry about that.

What's the point of using the profile name of someone else to join a campaign?

I understand that you want to limit the risks of losing money by doing this but where is the fun in that! Placing bets for hours and knowing in advance you are not going to win/lose anything!

You can earn some free money by participating in one of roobet's contests. It's really funny and you can earn without investing a single penny.
Keep an eye on the Games and rounds section so you don't miss any of them.

sorry about that, could't stop myself  

It took me about half an hour to find all the correct answers.
I've been here for more than three years now and I thought I knew all the forum sections/sub-sections but after finishing the game I realised I was wrong.

Got 49 but to be honest, I cheated a little bit  
I didn't use the developer mode. What I did is entering the most used letters like "e", "s", "i" ... and search on the forum home page for matches. I always found the correct answer without having more than 3-4 wrong letters.

حسب ما قراته حول موقع tunisiabtc فهو موقع موثوق و يعمل منذ مدة لا باس بها لكن مؤخرا لاحظت وجود بعض التشكيات بسبب بطئ الاستجابة للمعاملات و يمكن ان تبقى عالقة لفترة حتى يتم الاتصال بالفريق العامل بالموقع.
لاحظت كذلك ان لديهم صفحة فايسبوك و سيرفر ديسكورد فيه مجموعة من الاعضاء يصنفونهم على اساس موثوقين و لا اعرف صراحة على اي اساس قام هذا التصنيف!
و هم عادة من يقوم بدور الوساطة بين الاعضاء الجدد.

عند التعامل مع اي شخص و طلب استعمال وسيط، تحقق من رابط حسابه جيدا فقد كثرت عمليات التحيل باستعمال حسابات مزيفة مشابهة لحسابات الوسطاء الموثوقين.

قمت بتفقد الموقع و الامر الملفت للانتباه هو الفرق بين السعر الذي يشترون به و سعر البيع. الفرق كبير جدا و غير مبرر يصل لحوالي 30%
يشترون بسعر اقل من سعر الدولار حسب صرف البنوك و يبيعون بسعر اعلى من سعر السوق السوداء!!

شكرا على الموضوع.
كلامك صحيح فتعدين البيتكوين عادة ما يقارن او يشبه بالتنقيب عن الذهب لصعوبة العملية و ارتفاع تكلفتها و هناك حتى من يطلق على البيتكوين تسمية الذهب الرقمي لتشابههم في عديد الخصائص و لعل اهمها ان كليهما لديهما قيمة مادية و يمكن استعمالهما كوسيلة للمبادلات و الكمية المتوفرة او التي يمكن استخراجها محدودة و نادرة.

لكن صراحة لم افهم ما معنى كهف البيتكوين و المواقع التي يمكن استخراجها منه!

You can use any reputable wallet for this.
And as suggested above, disabling the "use change address" feature will do the trick. The only inconvinience is when using a hd wallet this will not stop it from generating a new receiving address when the current one has been used and you may mistakenly give the newly generated address to the sender.

To solve this, choose one of your wallet's addresses, export its private key and import it to a new wallet. This way you can rest assured that you will be always using the same address for both sending and receiving.

Thanks o_e_l_e_o for the info. I didn't know about these vulnerabilities.
I know that there is no 100% secure device but didn't expect there were a vulnerability which allows the attacker to steal funds remotely... this is a bit concerning!

AFAIK, vulnerabilties that require physical access to the device aren't that easy to exploit.

If your wallet is fully synchronized then there is really no need to use a block explorer as your wallet will show all the info related to your addresses and using a block explorer may complicate things if you don'k know which address you used as input. So better keep it simple.

You can use blockchair.com or blockchain.com if you like.


If your transaction stays unconfirmed for a long time because of low fees and it was flagged as rbf, on Electrum, right click on the unconfirmed transaction and select Increase Fee then set higher fee rate for the new transaction.

don't be,
What you see on the Send tab under Outgoing payments are just invoices. You can delete them or leave them there as I believe they will be automatically removed anyway.
Probably, you saved a copy of the first transaction before you broadcast it!

You can see the broadcasted transactions under the History tab.

You have two options, either to remove the invoice to avoid any confusion and create the transaction from scratch or right click the invoice and choose Pay, set the fee rate then click Send.

Since there is no known vulnerability or a bug affecting the most popular hardware wallets that can result in your funds being stolen, I don't see how paper wallets can be more secure than hardware wallets!
By using a hw you can sign transactions without having to disclose your private keys. However, when using a paper wallet, you will have to import the private key into a third party software and you will have to take extra precautions to ensure your private key doesn't get leaked.

AFAIK, Electrum doesn't allow double spending. You can't use the same UTXOs that have been used in a previous transaction unless your transaction has the RBF flag and even then you will have to click the bump fee button.
Also, you can't send a zero-fee transaction on Electrum. The minimum fee rate is 1sat/byte.



if the second transaction doesn't appear in the history tab, then it hasn't been broadcasted.
Just delete the invoice and start over.
