4061  Economy / Service Announcements / Re: Bitamp Bitcoin Web Wallet - Send & Receive Bitcoin Instantly! on: June 26, 2020, 05:14:06 PM
The Bitamp wallet provides a nearly similar wallet like Myetherwallet, from what I see by visiting the site.

Would you mind sharing more about the truth behind the scene, please.

Your service claims that everything with create, log in wallet are stored on browser, device, not on the Bitamp wesbite but I am curious and would like to know that how to know the claim is true?

I only want to know about a technical issue, that is the same as probably fair on casinos. If you can help, please do it.

Thank you.

If I'm not mistaken, the person who started the thread here is the same person who wrote the article on Medium.

He's got accounts both on this forum and on Medium and he's just posting here what he already posted on his Medium account. That does not appear plagiarism to me. I think he's doing it for the sake of traffic.

However, I preferred the user's OP here to be the summary of his/her article. One does not have to copy-paste the entire long article. He/she could have preferred to open the thread with only the gist of his/her article and then provide the link for those who wish to read the long version.
Users have to leave source links because without source links, it will be considered as plagiarism. Quote blocks are good alternatives.

There is no need for investigation that users who make posts here are the same people of the original documents. At first, it will be considered as plagiarism. If plagiarism appeal is submitted, investigation will be taken but it is best to always leave source links. Even you are owners of original documents because it saves your time for any troubles or appeals.

If I am owner, I don't have any inconveniences to leave source links. Most of people don't leave source links are plagiarizers.

Both are presented there. The left side amount is total frequency and the right side is the percentage. I have presented both.
There is no note on it in OP, in text or on graphs. You should add notes, in text or on graphs.

IMO, you mess graphs up with the combinations of frequency and percent.
4064  Other / Beginners & Help / Authentication: Types, Risks/ Attacks, Advice on: June 26, 2020, 01:50:03 PM
People usually care about increasing their funds, their capital but do neither care about losses nor pay attention to protect their funds/ capital. There are some reasons why they don’t care about it.
-   Don’t aware of risks if they don’t protect their accounts.
-   Don’t have knowledge.
-   Being too lazy (aware of risks, have knowledge, but they don’t do anything to secure accounts).

How many types of authenticators?
-   SMS-based/ Email-based/ Voice-based/  Biometric-based authenticator
-   2-factor authenticators (2FA)
-   FIDO U2F hardware authenticators

Which one is recommended to use and should be your first priorities?
2-factor authenticator softwares. They are free and more secured. Try to use Yubikey if you actually want to secure better with some funds.
Don't use SMS-based authentication if you can do it. Unfortunately sometimes you don't have choice because service providers (like banks) don't only give you that type of authentication. As being said, whenever you can avoid this type, avoid it.

The first type is less secured and more risky because there are SIM swapping attacks (for SMS, voice code) and if you rely on email, your account will be compromised if hackers have access to your email.
[BEWARE] Sim Port Attack and SIM swapping protection
With SMS-based authenticator, you can secure it better by set up PIN code for your SIM card, deactivate lock-screen notifcations. More details in the guide from Kaspersky.

Biometric-based authenticator is risksy because if you pass away, your family members can not get access to your account.



The second type is more secured and is the one should be used. Most of them use the OATH TOTP (Time-based One-Time Password) algorithm.
There are some softwares for you. More details

Google Authenticator: Android, iOS
Duo Mobile: Android, iOS
Microsoft Authenticator: Android, iOS
Free OTP: Android, iOS
Authy: Android, iOS, Windows, macOS, Chrome
Yandex.key: Android, iOS
Aegis: Android
When using those apps, there are mandatory steps to do: backup 2FA codes (to recover later if your phones / devices broken and can not be prepaired), and test the validity of those backup codes (make sure that you make good backups and they can be used to recover).

Some people don't know these two important and vital steps. They activate 2FA on their accounts, enter 2FA codes to apps, but don't back those codes and don't test backup's validity. If their devices are stolen or broken, they get troubles.

Some advice for 2FA
- Make backups of 2FA codes before activating it
- Activating it by manually entering 2FA codes, don't scan QR code.
        Because when you entering 2FA code manually, you also check the validity of your code backup.
        If your code backup is not correct, you can not activate the code for your account.
- Retest code backup on another device if possible.
- Don't take a photo and store code backup on your device. There are risks that your devices can be compromised and photo or backup will be leaked.
- Install 2FA app on your another device, and it should mostly be offline. Don't store all eggs in one bag.

Remember that there are two layers of backup: backup codes, and 2FA secrect key (or bar code). I advise you to do backup for both of them, or if you choose only one to backup, it should be 2FA secret key, not barcode. With secret key, you will be easier to guess if character, figure are blurred a little bit but with bar code, it is almost nothing to do. Of course, saving 2FA secret key backups as best as possible is the must thing to do.

Store them offline.

2FA secret keys


FIDO U2F hardware authenticators: YubiKey and others
U2F hardware tokens are the darling of security specialists, primarily because, from a user perspective, they work very simply. To get started, simply connect the U2F token to your device and register it in a compatible service. The whole process takes just a couple of clicks.
It is not an exact comparison but you can imagine 2FA-app and Yubikey like non-custodial wallet softwares (Bitcoin Core, Electrum) and hardware wallets.

Many members was in the same situation like you, newbie in the beginning 😀
We also didn't have knowledge and experience in the beginning but learned and became more experience over time.
So,  if you invest your time and effort here slowly you will get some experience and knowledge and be able to join different discussions and contribute to the forum.
Don't worry,  just read other posts and study about btc. 
We all begin as newbies but some people are always newbies no matter which ranks they have. Before January 2018, they can rank up to top ranks but after that month, they can not. Consequently, they are forever newbies, from the aspect of ranking and from the aspect of knowledge.

Newbies forever, if don't read, learn and contribute. It is about ranking.

Many newbies has dropped out in the forum because of lack of encouragement from the seniors
Encouragement can be found from the users who have the same rank as yours, not from senior members.

You can  see lot of encouragements from The future of Bitcointalk: Low Ranking Top Merit earners in the past 30 days. It is more fitted lessons and encouragements for you because it's your rank, and the challenge is the same, the lessons can be learned and applied.

many beginner's has determination for the forum but it has been taking off because no support to step in next rank.
Encouragement ~! rank or merit
There are many forums that don't have restrictions on ranking. You can make posts and rank up. If it is the encouragement you find for, you can join those forums: bitcoingarden.org, cryptotalk.org. They are small forums, and very good forums for spammers. The forum is bigger, and need restrictions on ranking up as well as more rules to keep it healthy.

If you have time to read and compare, please read and compare rules of the forum and those two forums. You will see big differences.

4074  Bitcoin / Bitcoin Technical Support / Re: Sending USDT to BTC address on: June 25, 2020, 07:54:39 AM
The OP has likely sent USDT in Omni layer which has been built on top of bitcoin blockchain.
USDT addresses in Omni Layer are bitcoin addresses and that's why Binance allowed OP to send tokens to a BTC address.  

Take a look at Omni explorer.
All addresses are bitcoin addresses.
There are three chains for USDT now: Omni layer that is built on Bitcoin blockchain; ERC20 that is built on Ethereum blockchain, and TRC20 that is built on Tron blockchain.
ERC20 tokens have the address format of Ethereum address, but they are not ETH. More important, the problem of OP is he does not have any control on private key or mnemonic seeds of the address. In crypto "Not your keys, not your bitcoins; not your keys, not your crypto; not your keys, not your funds".

It is not a discrimination between global and domestic exchanges but domestic exchanges tend to be small and their supports probably not good enough. Moreover, big exchanges do not mean that they must or always provide such recovery services for users. If they have such recovery services, the fees often are high. If fees are higher than what people can get back, it is out of luck again.
Here are some very important concepts to learn if you are going to continue to use Bitcoin. Please take a moment to read through this post:

The reason that "blockchain" couldn't help

The company called blockchain that runs a website called blockchain is not THE blockchain.  Imagine if I were to create a company called "Internet Services", and that my company has a website that lists the names of all the internet email providers that I know of.  That doesn't mean that I am in control of THE internet or of any of those company's email services.  If you were to send an email from Google's gmail service over THE internet to someone else's AOL email address, and that email were to fail to arrive...  Calling my company that publishes the list of email service providers isn't going to accomplish much.  I'm not Google (the provider that you sent from). I'm not AOL (the provider that you sent to). I'm not THE internet (the technology that you used to send the email).

That's what happened when you tried to contact "blockchain".  There is a company called "blockchain". They provide a website that lists all the blocks that they know about in THE public blockchain. That does not mean that they are in control of the blockchain, or any of the services that make use of that public blockchain.  When you sent bitcoins from Coinbase through THE blockchain to someone else's service and those bitcoins failed to arrive... Calling the company that publishes the list of known blocks isn't going to accomplish much. They are not Coinbase (the service provider you sent from). They are not the service provider that you sent to. They are not THE blockchain (the technology that you used to send the bitcoins.

It can be confusing that there is both a technology called blockchain and a company called blockchain.  The company did not create the blockchain (they came along later and just named themselves after the existing technology).


The reason Coinbase couldn't help

Coinbase provides you a place to acquire bitcoins, and sends them elsewhere on your behalf.  Bitcoins are not an electronic "account" like you are used to with a bank.  It works more like an electronic representation of a CASH (paper and coins) transaction.  If you pay someone $100 with an electronic account (like a credit card) you can contact the company that provides that account and they can cancel the transaction.  If you hand someone a $100 bill, and they walk away...  The money is gone.  There is nobody to call.  The only person that can give you that $100 back is the person that you gave it to.  When you "sent a transaction from coinbase" what actually happened was that you asked coinbase to give some of the bitcoins that they were holding on your behalf to someone else (more specifically, to a bitcoin address that was not under their control).  Once they turned over those bitcoins, there isn't anything coinbase can do to get them back.  The only person that can give you the money back (or access the money at all) is the person (or company) that controls the address that you sent to.


The reason the receiver is having difficulty getting their service to fix this

Managing control over crypto-currency requires the use of digital keys.  Each address has a key that will allow controlling of any funds at that address. The ONLY way to control those funds is with that key... AND... ANYONE with control of that key (or a copy of that key) can control those funds.  Now imagine you run a service (similar to Coinbase) where you are managing the funds of thousands (or millions) of people on their behalf.  That means your service has thousands (or millions) of keys to keep secure. If a disgruntled employee can get their hands on any of those keys, then they can steal funds from your customers.  Therefore, you need to have extremely strict control over who can access the keys and how they are accessed.  Also, if you were to lose any of those keys, the funds would become permanently inaccessible.  It is possible to copy keys, but it is not possible to re-create a key without a copy of the original. Scammers, thieves, and other criminals will contact the service regularly, pretending to be a customer with an unusual situation and ask them to do something out of the ordinary with the keys in hopes of gaining control of the funds or tricking the service into sending funds.  It is this high level of security and caution with their customer's funds that makes it time consuming and difficult to subvert their normal security processes to acquire a BTC key for a BCH address.  Because of the time, difficulty, and risk... many services will either refuse to help or will require a significant fee to help in a situation like this.

However, the receiver's service is the ONLY entity that CAN fix this

Since the receiver's service is the entity that controls the digital keys of the address that you sent to, and since it is impossible to control funds without that digital key... You are at the mercy of the receiver's service.  If they are unwilling to help you, then you either need to find a way to force them to help, or you need to consider this an expensive lesson in being careful about where you send your crypto-currency.

Crosschain - A deposit of one coin to a different coins address is considered a crosschain deposit

Bittrex will only attempt to recover crosschain deposits that exceed $5000 at the time of deposit, within 7 days of the deposit and will charge a 0.1 BTC for this recovery. Recovering coins crosschain is an inherently dangerous and time consuming process.

Don't depend on any softwares to protect your funds because softwares need to be updated and there are always new threats released by bad guys. It does not happen too often but sometimes databases of AV software companies are outdated and don't have protections on newest and dangerous threats. In such attack events, if your computers are affected with the newest dangerous viruses, your data and your funds will highly be lost/ stolen.

LOCAL RULE : Only Full member and above can post on this thread.
Why? Everyone deserve rights to secure their services.
Maybe also require user to sign a message when posting so it add another layer of security.
People can stake a bitcoin address and sign a message with telegram usernames in the example format.
Stake your Bitcoin address here
Code:
-----BEGIN BITCOIN SIGNED MESSAGE-----
dd/mm/yyyy I'm username from bitcointalk forum. My address: your btc address
My telegram : your telegram username
-----BEGIN SIGNATURE-----
your btc address
your sign message
-----END BITCOIN SIGNED MESSAGE-----
It can be used but why trusted members have to hide their trades and discussions with telegram. Trusted members don't have such needs. They can discuss on Telegram but they don't usually do this. Only suspcious and untrusted members direct you to telegram or other messengers to discuss.

Some people mess up their stuffs in the message and create difficulties for others to verify their sign message.
try changing stuff in the message (add space, add new words,...) and take the same steps. that site will always show you a different address no matter what!
