Many of user use QR code to send or receive QR code. Basically, who use a smartphone for sending Bitcoin they use QR code to spending Bitcoin or Cryptocurrency.
We know that a few days ago a network of Bitcoin-to-QR-code generators has stolen more than $45,000. So be careful when you will use QR code.
For your safety, you must check the address multiple times after scanning the QR code. Otherwise, you could be a victim.

It's why I never use QR code or Copy-paste Bitcoin address. Better to type one by one although can spend a bit times to write and check address multiple times to confirm it. Don't be too lazy if you want be more safe.

From your link, we should stay away from this website

I also shocked this case also have been discussed on 2 years ago QR Code replacement scam (https://bitcointalk.org/index.php?topic=2696238)

Using the QR or copy pasting isn't the issue. That's just a shortcut. You paste/scan the QR, verify the address and go on with the transaction. And you don't just use a random QR generator you found in the internet. Instead, go with something more trusted (like Blockchain.info or an open source tool) and always verify.

I don't think literally typing all characters one by one is really necessary.

Isn't too lazy as well by typing all the characters one by one? :P


Also just 7 days ago > {Warning}: Fake Bitcoin QR Code Generators (https://bitcointalk.org/index.php?topic=5235014.msg54085900#msg54085900)

I doubt anyone in this earth would do that. I was mistaken, I would not believe if anyone would tell me rather than writing. I believe written stuff. I would never do that. It's pretty easy to copy and paste then find similarity between the address. Hacker will never be able to replace with same address as of your sending address. One or two or couple of characters are exception, they may be similar coincidently.

I think blockchain.com explorer provide the qr code option. It's pretty easy to get the qr code from there.

Sometimes I have experienced issues while scanning through wallet apps, the best thing one can follow instead of scanning you can copy and paste the address to your wallet and then send the coin to exchange.

Damn, so I just found only 4 links? {Warning}: Fake Bitcoin QR Code Generators (https://bitcointalk.org/index.php?topic=5235014.0)?

Not just Bitcoin, money, somethings related to money. At some point, we will realize that what we are eating is fake   :P everything related to money will be fake, one way or another, can be fake to steal money, can be fake quality, can be fake to sabotage, the ultimate goal is still is money  ::) Damn those who make money illegally  ::) There are thousands of ways they can use their brains to make money (these guys are usually smart), but they choose the dirtiest way to earn :-\

QR code is just another type of display for your key inside your wallet. So losing your QR code or your key is not different on potential risks. But QR code is more risky because it is more convenient for bad guys to try and test it. They will have to spend more time (if they are not professional, of course) to type or Copy & Paste key manually.

I never use QR code, for my exchange accounts to my wallet and my 2FA code. I type them manually to activate and back them up in characters, not QR codes.

That's sad, one of the best to send of Bitcoin especially in some physical stores that accept Bitcoins is through QR codes.
My piece of advice is also to double-check the bitcoin address generated by the QR address. That's my habit, even crypto/non-crypto, I always double-check the result of QR codes, like the bitcoin address generated, like some first few digits or some last digits of the address for confirmation before sending your Bitcoin.

It's really very sad news. The scammers are very intelligent and trying there best to steal someone's money. Every day we are hearing some news that people scammed continuously in a new and unique way. Scammers also running their unique strategy every day. They will not stop their journey. Only our awareness can save us. we should aware of every step in crypto world. So just want to say what TryNinja said, It does not matter you do copy-paste or user any QR code generator but we need to recheck again and again the wallet address word by word. Not just the first few words and the last few words. we should check all the words at least two times before making any transaction.

What are you talking about?


Type one by one?
I've never done that even once in all those years and hundreds of transactions.
And yeah, I've used even QR codes when telling an ATM where to send the codes or when I was paying for something.

I imagine myself in front of an ATM and typing my address one letter at a time and checking it a hundred times because I'm sure I'll get one or two letters wrong making it invalid. Probably the police will pick me up before I manage to finalize the transaction, thinking I'm trying to break the ATM.

I can't understant why would anyone use an online tool to generate the qr-code when every decent wallet app have this feature integrated by default!

In case their wallets do not allow generating qr-codes or for any other reason they have to use an online tool, the least they can do is to decode the provided image and read it using any qr scanner/decoder to make sure it contains the right address before using it.

The most important thing note is;
1. Never use third party or random QR code readers. Most wallets have inbuilt QR code readers. If they don't have, Just copy and paste the address and recheck it after pasting to be sure it's the same address you copied

2. Even after using the Wallet's inbuilt QR code, always cross check the addresses and amount to send/receive. It takes only a few seconds.

I agree with your words. We must check the address multiple times before spending our cryptocurrency.

You are absolutely right most of the user lose his/her money for their Laziness. If you love your money, you should be a hard worker and aware. Always a lazy man fails in to do any work, that's why they are always a loser. So don't put down yourself on the failer line.

Till now Using QR code to send Bitcoin isn't secured and suitable.Thats why I will recommend everyone not to use QR code until being safest.
So Safe your funds and send it in correct way.

Lmao, how about copy paste and check address again? You will make even more mistakes if you write one by one.

:O crazy that they created so many websites
You need to ALWAYS confirm address before clicking SEND. Make sure no trojan horse changed your copy-pasted address or any qr-code generator etc
Security is most important in Bitcoin, its huge problem for wider adoption
