A PERTH businessman selling his $1.4m family home for the digital currency bitcoin says an interested buyer is jetting out from the United States to view the property.

As revealed by The Sunday Times, Cliff White, 43, is the first person in Australia to offer his house for the virtual currency.

The owner of Extreme Clean Australia, he has spent $10,000 buying bitcoin since 2010, the year after it was launched.

Bitcoin's skyrocketing value means the father-of-four's investment is now valued at more than $1m.

The price of a single bitcoin, which can be traded online or "mined" through powerful computers that crack complex algorithms, is currently worth $750.

If the house sale completes, Mr White plans to keep the proceeds as bitcoin in the expectation its value will continue to grow.

He has owned the house, which overlooks a lake in Parkerville, in the Shire of Mundaring, east of Perth, since 2001.

"I found the concept really fascinating, but to be honest it was doing my head-in because I couldn't understand the mining side of it," Mr White said.

"I then got into the trading side of it and thought 'wow, there is some real movement here'. I bought it low and watched it go to $32 and watched it plummet it back down.

"All the time my wife was saying 'are you serious? You know nothing about this'. Over time we've come to understand it more.

"I believe it will take over things like Paypal. It's seamless, it's fast, it's secure. I believe in it so I thought, well, why not put my house on it?"

Since posting an online advertisement for his five-bedroom home last month, he has received 60 emails from potential buyers.

One of them, a 21-year-old man from Houston, Texas, is flying to Perth in January to view the property.

Mr White said the prospective buyer was a bitcoin "miner" who already owns several investment properties in Australia.

"He obviously got in very early so he would have a good amount of bitcoin. To have the ability to buy something substantial as bricks and mortar is a unique thing," he said.

A big challenge, Mr White said, was finding a settlement agent with knowledge of computerised money transfers.

"I've spoken to a couple of settlement agencies and they're very nervous about it because they just don't understand it," Mr White said.

Mr White said he had ridden the bitcoin "wave" through the years and believes its value will continue to rise - potentially as a high as $10,000.

"I know there is a lot of non-believers out there. The attention now has started to come on because the value has started to increase," he said.

"No-one was too interested when it was $2, $6, $8 - even up to $50-$60, but you can make some really good money on it if you are wise about it.

"It is trading at the end of the day, there are risks, absolutely. But to sell the house on it, I just thought 'well, it's unique, I'll be the first in Australia' and if nothing else, I believe in it."
