The problem was, he hadn't made any of the transactions.
It turned out scammers had cleaned out his cryptocurrency portfolio and now, six months later, the couple have lost any hope of getting their money back after investigations hit a dead end.
"Initially I was going to have to work 'til 58, now I'm going to keep working 'til 65," Manu Kundra told news.com.au.
To make it worse, if the money had remained in the account, by now it would have grown to a whopping $150,000.
Police investigations found the money was initially transferred to an account with an IP address in Turkey.
The money was then sent to another account in Nigeria where it has since disappeared for good.
NSW Police confirmed to news.com.au they are unable to pursue their investigation any further because the cyber criminals are outside their jurisdiction.
At the cryptocurrency peak in November last year, Kundra's investment would have worth a whopping $150,000.
"That was part of my strategy to get money for my retirement," Kundra said.
The Sydney family man initially had no idea how the hacker had hijacked his account and was worried his devices had been infected with malware, including spyware that was tracking his keyboard strokes.
He employed an IT professional and they didn't find any signs of malicious activity.
Unfortunately, he later discovered the email address linked to his cryptocurrency account had been compromised in a widescale data breach that involved one million other people.
His email and phone number had been sold before being dumped publicly in June 2020.

$750m of crypto stolen globally
A report from crypto data company Chainalysis released last week found that cryptocurrency-based crime soared in 2021.
More than $750m worth of cryptocurrency was stolen from people like Kundra last year.
North Korea-affiliated fraudsters were the worst, responsible for $400m of cryptocurrency hacks in those 12 months.
Most of these scammers used legitimate centralised cryptocurrency exchanges to send the stolen funds to, then transferred it to another untraceable account.
