Flash BTC Technique — MANUAL + Bonus
Flash BTC Technique — MANUAL + Bonus
⚠️ Attention: Before we begin, be cautious: there’s no real tool to send unlimited bitcoins or flash coins. Many scams claim otherwise. I’ll explain the real process in this blog. Practically step by step on Mobile Phone (in next blog) as well as on Desktop.
It’s 2023, and since past few years people are reporting cases where they receive Bitcoin (BTC), but then, after a little while, it just disappears. Imagine having money one moment and then it’s gone the next. That’s what’s happening to some crypto users.
There’s a dark side to this innovation: scams. Scammers are finding clever ways to trick people and take their hard-earned BTC.
Basic Theory Concept
Basically it’s RBF, or Replace-By-Fee, is a feature that allows users to increase the fee of a Bitcoin transaction after it has been broadcasted, aiming to speed up confirmation. People misuse RBF by deliberately sending a transaction with a low fee and then constantly increasing it using RBF until the transaction is confirmed. This can tie up funds or cause confusion, potentially enabling dishonest practices.
The point is that you can send BTC from Electrum wallet and cancel the payment.
How does it work?
You send a transaction with 1 sat/vB fee, then you cancel the payment inside the wallet, making the transaction fee higher, for example 5 sat/vB, and the past transaction simply disappears from mempool because the new fee (5sat/vB) overcame the old one (1sat/vB).
Advance Practical (PC/Desktop)
Here I will tell you how you can send BTC and after a certain time cancel the payment and get your money back.
You will need following things:
✅ Electrum wallet
✅ BTC coins
Electrum wallet installation
We need to download the old version of electrum, as in the new versions there is no function to cancel transactions.
Version for electrum you need to download 4.3 from the link:
For Windows, look for the file “electrum-4.3.0-setup.exe”, this is the installer.
For macos, look for the file “electrum-4.3.0.dmg”.
Part 1. Creating a wallet
In order to cancel transactions you need to download Electrum wallet (download). Download, install and see this:
Click next. Choose the standard wallet.

Part 2. Setting up and replenishing the wallet
Go to Tools -> Preferences
Tools -> Preferences
Change “Currency” in the “Appearance” tab from mBTC to BTC.
Done. Now let’s proceed to replenishing the wallet.
Open the “View” tab and select “Show Addresses”.
The “View” tab
Select “Show Addresses”.
Go to the “Addresses” tab that appears.
The “Addresses” tab
Right-click on the address, go to “Copy Column” and copy the “Address” column.
Copy the address of your BTC wallet
Deposit the copied address of your bitcoin wallet.
Part 3. Sending payment
After you have funded your wallet, we start working with sending and canceling payments. Go to “Send”. Fill in the data.
Go to “Sending” and fill in the data.
Then click “Pay” and set the minimum commission (slider to the left). Enter the password and press “Send”.
The window after pressing the “Pay” button
After pressing the “Send” button we get the following window. Payment has been successfully sent.
The payment has been successfully sent.
Part 4. Canceling a payment
After sending the payment, go to the “History” tab and see the first payment “Uncofirmed”.
Right click on “Unconfirmed” and see the following:
Right click on “Unconfirmed”
Click Cancel (double spend). In the window that opens, put a new commission rate above 1 (15–20 sat/byte) and click “OK”.
Window after clicking on the “Cancel (double spend)” button
Press “Sign” button.
The window after clicking on “OK” button
Enter your password and click “OK”.
Entering your password
After entering your password you are returned to the main window and you need to press the “Broadcast” button.
Click the “Broadcast” button
After the window “Payment sent” appears, the money will be returned to your Electrum wallet balance.
If you send a payment with 1sat/vB commission, it will wait for confirmation (depends on mempool’a, I will tell you about it below). After the first confirmation you cannot cancel the transaction in Electrum.
BONUS: Finally, Let’s learn about mempool for tracking workload for number of unconfirmed transactions.
Site for tracking workload: https://mempool.space/. When opening the site we see the following:
Get interested in priorities and number of unconfirmed transactions. You can start working under the following conditions:
1) Unconfirmed transactions should be more than 5000
2) High Priority is more than 10 sat/vB.
Under the conditions described above, the transaction confirmation time will be from 60 to 200+ minutes. This is more than enough for safe work and safety of hacker’s / scammer’s dept, because every transaction, with rare exceptions, we cancel after 10–30 min.
Scammers often use misleading messages or promises of big profits to lure people in. They might send fake links that, once clicked, can give them access to your digital wallet. It’s crucial to be vigilant and cautious. Don’t let the excitement of cryptocurrency blind you to the potential risks. By staying informed and taking necessary precautions, we can make the crypto space safer for everyone. Let’s look out for each other and enjoy the benefits of cryptocurrency without falling prey to scams.
