“Irrational returns on BTC will result in SMSF trustees taking further positions and investing in additional crypto assets for fear of missing out,” said Ms Banton.

The hype around cryptocurrency, she warned, has seen a number of phishing schemes emerge in the past couple of years, with the Australian Competition and Consumer Commission (ACCC) receiving 245 reports of bitcoin-related scams in October 2016 with losses totalling $92,000.

While there are many safeguards protecting BTC wallets against hackers and scammers, such as two-factor authentication and encryption, a lot of the scams, she said, involve fake website that mimic legitimate websites and steal a user’s account details when they try to log in.

“Even the most alert and tech-savvy SMSF trustee can be taken in by scammers who can manipulate Google Search results and direct traffic to a fake, cloned BTC exchange website,” she said.

Ms Banton said there have also been examples where other types of cryptocurrency have collapsed due to cyber security incidents.

The most notable one she cited was with The DAO, another type of cryptocurrency which at one point raised over $34 million in 2016 through a crowdfunding campaign.

“When hackers found and exploited a vulnerability in the technology, they siphoned off one-third of The DAO’s funds, resulting in traders dumping The DAO by the truckload,” she said.

“There’s no doubt that the frequency and impact of cyber security incidents will continue to increase and adversely affect crypto assets.”
