Bitcoin ATM Fraud: Four Canadian Men Declared Wanted

Published

on

Four men have been suspected and declared wanted by the police in connection with the Bitcoin ATM double-spending attacks.

According to a report published by the CBC. four men have been suspected and declared wanted by the police in connection with the double-spending attacks at Bitcoin ATMs. According to the report, a hundred and twelve transactions took place in just September 2018 out of which around sixty-six (half) of these took place in Calgary and others in Hamilton, Toronto, Winnipeg, Montreal, Ottawa, and Sherwood Park. However, the men that are suspected have unknown identities and the local police are seeking the help of the public in order to identify them.

 

Bitcoin ATM: Double Spend Fraud

Bitcoin ATMs installed in these areas had a zero-confirmation transaction which means that even without a single confirmation, the bitcoin atm allowed the withdrawals which made it possible for the suspects to perform double-spending in these ATMs.

The alleged persons performed a hundred and twelve transaction averaging to around $1800 per transaction in just ten days of time and made more than $200,000 out of it.

 

How does Double-Spending Work?

Double spend is made possible due to tools developed by Peter Todd, a bitcoin core developer who resides in Canada. The tool called replace-by-fee-tools allows the user to ‘unstuck’ and ‘stuck’ transaction by paying extra fees. However, the tools were not developed or endorsed for performing such criminal activity at a bitcoin atm.

According to Peter Todd, the double spend tool creates two transactions in sequence out of which the 1st transaction makes the stated payment to the stated address and the 2nd transaction double spends the same transaction with a transaction which has a greater amount of mining fee, making the payment only to the change address. Also, the user can choose to state that the 1st transaction additional OP-Return, Multisig as well as Blacklisted address outputs. As many bitcoin miners would not accept the transactions that have these kinds of outputs, instead they will accept the 2nd transaction that is a double-spend transaction which indeed assists the user to double spend.

Kevin O’Leary calls Bitcoin Worthless

Famous as the founder of Softkey, a startup that earns annual revenue of around $29 million and a host on the American business reality series Shark Tank, Kevin O’Leary is a celebrity amongst the business class in the United States of America.

 

During the interview published on 14th May 2019, Kevin expressed his thoughts over the king of cryptocurrencies bitcoin and called it a useless currency as the people who accept it just wants to hedge against the high volatility of the virtual currency. This comes in the midst of the current bitcoin surge as the virtual currency doubled its value in just a few days from below $4000 to more than $8000.

 

Kevin also explained why he has such negative views on bitcoin giving the instance of how once he tried using bitcoin for a real estate transaction in Switzerland. He said that it is not possible to get in and out of bitcoin while transacting in huge amounts.

 

He also gave an example stating that if one wants to buy real estate in Switzerland for $10 million. The seller wants a guarantee that the value comes back to him as currency at ten and the buyer has to hedge the risk of the cryptocurrency, hence it is not a real currency. Kevin said that the seller or the receiver would never want to take the risk of such high volatility and thus BTC is worthless.

Amazon Owned Whole Foods, Other Big Retailers Start Accepting Bitcoin

Whole Foods, which is owned and operated by the e-commerce giant Amazon and other big retailers are now going to accept payments in bitcoin.

Whole Foods, which is owned and operated by the e-commerce giant Amazon and other big retailers are now going to accept payments in bitcoin.

 

Whole Foods and Others accepting Bitcoin using Spedn:

A company called Flexa in collaboration with Gemini exchange which is owned by the Winklevoss Twins has managed to persuade a lot of big retailers including Nordstrom, Crate and Barrel & Whole Foods to configure the same scanners that they are already using for payments from other digital wallets like Apple Pay to work with their cryptocurrency payments app called Spedn.

 


Everything is handled on the backend of the application so that the cashier need not even have heard of bitcoin, let alone understand how to manage payment in cryptocurrency. The merchant has the choice in receiving immediately converted fiat or actually taking and holding the cryptocurrency.

 

The Spedn app lets consumers pay in bitcoin, bitcoin cash, ethereum and GUSD (Gemini Dollar), the Gemini backed stablecoin.

 

This new solution actually uses the existing systems and offers really only upsides for the companies as they don’t have to do any special training for their staff and there is no new hardware required and just a software upgrade.

 

It is worth noting that this is still in its early experimental stages for all the retailers which are cooperating with this scheme and things may of course change in the future. The thing to keep in mind here is that Bakkt is likely launching a massive payment processing service for cryptocurrency in the very near future as well and it could be a big competitor to what Gemini and Flexa are offering.

 

The company will also need to prove itself with consumers and get people to actually go out, download and use the Spedn app.

 

Can this be a game changer in retailer adoption of bitcoin and cryptocurrencies? Let us know about your thoughts in the comments section below.
