Suggestion:
The mine locations should be generated using a server secret plus a client secret this way the house could not cheat or pick the tiles at their advantage.
Just to add on this, in case LiveMines team decide to implement what you suggested..  The server seed must be generated and shared (hashed) with the user before the latter provides his own seed.

اعتقد اكثر شخص يمكن يفيدك في هذا الخصوص هو الاخ SyGambler.

شخصيا افضل ان لا اقوم بالتحويل على ان اتعامل مع المحتكرين.
على المدى البعيد، الحل الامثل للقضاء على الاحتكار هو تشجيع اكبر  عدد ممكن من الناس للدخول في هذا المجال.

نعم صحيح كلامك أخي Omega لكن لا يمكن استيراد المحفظة الا على نسخة الحاسوب و لا يمكن الاستيراد على نسخة الهاتف.

عند استيراد المحفظة على الحاسوب يجب بعد ادخال Seed الضغط على "Options" و التعليم على "BIP39 seed" حتى تتمكن من الاستيراد بشكل صحيح
(هذه الخاصية غير متوفرة على نسخة الهاتف لذلك يمكن استعمال الموقع الذي ذكرته)



بعد الضغط على Next يجب لتأكد من التعليم على خيار "native segwit (p2wpkh)" حتى تضمن انك قمت باستيراد نفس المحفظة و نفس العناوين.
عادة تقوم electrum تعليم الخيار المناسب بشكل تلقائي


4824  Local / العربية (Arabic) / Re: أسئلة شائعة: شبكة البرق on: January 04, 2020, 02:30:40 AM
@coupable,
يمكنك شحن محفظة شبكة البرق بالضغط على زر"manage funds" و من ثم اختيار المحفظة التي سترسل منها اما محفظتك  على bluewallet او محفظة خارجية. المعاملة يمكن ان تستغرق بعض الوقت حسب العمولة.

يمكنك فتح محفظتك على electrum بالاستعانة بموقع https://iancoleman.io/bip39/
قم بوضع seed في خانة "BIP39 Mnemonic"
تاكد من اختيار "BIP84" تحت Derivation Path
قم بنسخ المفتاح الذي سيظهر في خانة "Account Extended Private Key" و من محفظة electrum قم باختيار استرجاع المحفظة عن طريق المفتاح Use a master key و قم بنسخ المفتاح الذي تحصلت عليه من الموقع.

من المستحسن تحميل سكريبت الموقع و استعماله على جهاز امن غير متصل بالانترنات.

لنعد لأعضاء المجموعة : كان الغالبية المطلقة يشترون البيتكوين عند مشاهدة الشموع الخضراء الجميلة الفتّانة التي تغري العيون والجيوب
هناك قاعدإ مشهورة لدى لمستثمرين للبارون روتشيلد و هي "اشتري عندما تكون هناك دماء في الشوارع"
أي أن أفضل وقت للشراء هو عندما يقوم الجميع بالبيع و يكون السوق في حالة انهيار.

لكن لا يجب تطبيق هذه القاعدة الا عند الاستثمار في مشاريع قوية و كبيرة.

4827  Bitcoin / Bitcoin Discussion / Re: Vending machines that use Bitcoin on: December 27, 2019, 11:32:16 PM
It would be great to see such machines but I doubt any company will start manufacturing them anytime soon because of the small number of customers using bitcoin. Besides, the lightning network is still under development (testing stages) and using it requires some technical knowledge.
4828  Economy / Speculation / Re: Who is fooling around with btc Price? on: December 27, 2019, 10:28:36 PM
Check bitcoin price chart on CMC and you will realise that this has been the case since the first bitcoin introduced into the market.
Bitcoin price is known by its volatility and if you have been in this market for long time you would know that there is no manipulation here. The price of Bitcoin is only driven by the demand and supply law.
Don't  believe every thing you read. No one knows when the next bull run will start.

@OP, honestly it's hard to understand what you are talking about. You should elaborate more.
Keep in mind that there is a difference between cryptocurrencies and the technology they use which is blockchain.
The project promoted in the link you provided looks like a ponzi scheme to me where early investors get paid from funds deposited but those who join later.

4830  Other / Beginners & Help / Re: what is mean 1, 2 confirmation in bitcoin transaction. on: December 27, 2019, 06:18:23 PM
quote]
confirmation meaning you just now received your bitcoin.
Number of confirmations is the number of blocks that have been generated after the one including your transaction.
Number of confirmations can be seen as how safe the transaction is. The more confirmations there are, the harder for an attacker to tamper that transaction.
Ideally, 1 confirmation = 10 minutes but in reality it depends on the hashing power and the difficulty at the moment of generating the block.
4831  Other / Meta / Re: Session timed out while posting? on: December 27, 2019, 04:48:24 PM
My advice (other than already mentioned above), if you want to make a long thread or post, always copy the draft and paste it onto notepad.
In fact you don't have to copy-paste it into notepad. Just click "Preview" whenever needed and your text will be saved on forum servers for the next seven days.
If your text gets deleted while typing for one reason or another, just click the draft link and you will see your last saved drafts.


You can save up to 100 drafts.

I confirm that I received 80$ worth of Revain tokens as agreed. Thank you RevainSupport.
In fact it was a great opportunity for me as I learned more about the Revain project/platform which any crypto enthusiast needs.
I still have some questions regarding your project but I think it's better to discuss them on the announcement thread  Smiley
4833  Bitcoin / Bitcoin Discussion / Re: Time for YouTube to vanish ... on: December 26, 2019, 11:50:34 PM
Even if all the crypto community boycott YouTube, I highly doubt it would affect them or slow their business.
There are other great alternatives out there such as Twitch, Vimeo, dailymotion. But honestly, none of them can be compared to YouTube.

I find the reason for removing crypto related videos/adds not convincing though.
4834  Bitcoin / Bitcoin Discussion / Re: Please Help! (Bitcoin transaction) on: December 26, 2019, 11:04:51 PM
Do you have the private key or the seed for the BTC address? Is it a legacy address? If yes then it will be easy to recover your BCH.
Just import the btc address private key in your BCH wallet.
If you sent to a SegWit address then the recovery process may be more complicated.

If you sent your coins to an exchange or another platform where you don't have access to your private keys then you should contact their customer support and explain to them what happened.
4835  Other / Meta / Re: who is the founder of bitcointalk? on: December 26, 2019, 09:50:01 PM
I think he's trying to report that scam.
If I understood him well, then this is an extortion attempt not just a scam.
It would be better if he moves the topic to reputation section.
@OP, all you can do is to ask DT members to tag him.

By the way, theymos is the global admin and the one in charge here.
4836  Other / Beginners & Help / Re: how to send bitcoins to such address in message ? on: December 25, 2019, 03:36:25 PM
What wallet app are you using?
For example if you are using Electrum, just paste the URI in the "Pay to" field and all other fields will be filled automatically.

but I need a proof that this payment belongs to my user account !!

The website will generate a unique address for each user. However, I believe "327130" is your User ID on "www.xxxxxxxxx.website".
Check it out and if it is indeed your uid then "31jT3vtzwkrRksSixxxxxbCrw15QZYwNZg" is your deposit address.

I suppose you edited the address befor posting it here for privacy reasons because it is an invalid address (do not send to it).
4837  Other / Beginners & Help / Re: your own btc node. on: December 25, 2019, 03:02:41 PM
Here are the minimum requirements to run your own full node (as stated on bitcoin.org):
  • Desktop or laptop hardware running recent versions of Windows, Mac OS X, or Linux.
  • 200 gigabytes of free disk space, accessible at a minimum read/write speed of 100 MB/s.
  • 2 gigabytes of memory (RAM)
  • A broadband Internet connection with upload speeds of at least 400 kilobits (50 kilobytes) per second
  • An unmetered connection, a connection with high upload limits, or a connection you regularly monitor to ensure it doesn’t exceed its upload limits.
  • 6 hours a day that your full node can be left running.

It's a little bit outdated though.

Right now, blockchain size is almost 260Gb (exactly 255.000Mb according to blockchain.com). Therefore, you will need more than 200 gigabytes of free disk space as suggested above.
4838  Economy / Trading Discussion / Re: What kind of crypto trading do you recommend with $50 investment? on: December 24, 2019, 10:30:49 PM
Even with day trading, making small profit is not guaranteed.

Suppose BTC price is $7000. I buy $50 worth of bitcoin = 0.007 BTC
Then some hours later, it rises to $7500. Then I sell my BTC to earn USD = $52.5
But this is not always the case.
Cryptocurrencies are so volatile that it is very hard to determin the entry/exit points even for experienced traders.
What if you buy bitcoin at 7000$ but the price keeps dropping! You must have an alternative strategy to recover your losses.
4839  Economy / Gambling / Re: Roobet.com | The Honest Online Casino | Daily Presents + $5000 Christmas Raffle on: December 24, 2019, 05:05:23 PM
I got the email from "Roobet"

The email give me information about instant deposit bitcoin, did this feature will be no confirmation for the transaction of bitcoin.
I didn't receive any email from them. Maybe because I didn't make any deposit yet!
However, when you click on deposit you will see that 1 confirmation is still required:



Quote
You can get a problem if someone using "double spend" the transaction.
Not really, all they have to do is to disable withdrawals untill the deposit transaction has enough confirmations.

Can you explain honest how? Is your casino fully decentralized?
It doens't have to be decentralized to be honest.
4840  Other / Beginners & Help / Re: How best to secure your Private Keys and/or Seed phrase on: December 24, 2019, 04:41:26 PM
...
Use a hard drive...
Personally, I wouldn't rely on hard drives to store my private keys/seeds for long time (more than two or three years).
Some hard drives have a short lifespan (depending on the manufacturer).
I, once, stored all my important files on hard drive and didn't use it for two years. When I tried to restore them, I discovered that most of them were corrupted. So, I wouldn't advice anyone to use this method.
