Bitcoin fever has hit the real estate market with vendors across the world beginning to accept the cryptocurrency, including in Australia and New Zealand.
In America, bitcoin is viewed as offering foreign investors a way to dodge currency controls at home and US economic sanctions.
As of the end of last year, the digital currency was listed as a way to pay for some 75 properties for sale, especially in south Florida and California, according to the real estate firm Redfin.
"Bitcoin accepted" is a message now seen in the description of homes for sale in the Miami area.
One seller is going even further, saying he will take only bitcoin (33 of them to be exact) for his half-million-dollar downtown condo in the Florida metropolis.
Meanwhile, a home in Sydney's western suburbs could be the first property in Australia to be sold for bitcoin.
In December, a waterfront plot in Wellington was also put on sale in Bitcoin by Century 21 First Choice Realty. The property has not yet sold, but Century 21 owner Joseph Lupi remains confident that something will come through.
Bitcoin has been on a roller coaster ride of late, shooting up to nearly $US20,000 ($NZ 27,000) a piece in mid-December and then dropping sharply around Christmas. It started the year at around $NZ19,000.
It currently sits at just below NZ$19,000.
Its use in real estate transactions is novel, and agents are wary because of its high volatility.
"I'd be blown away if a year from now we see hundreds of real estate transactions in bitcoins," said Jay Parker, Florida CEO for the Douglas Elliman brokerage agency.
Still, such transactions can be useful for foreigners who want to invest in the United States and cannot otherwise do so, said economist and bitcoin expert Charles Evans of Barry University.
"This seems to be driven by international investors who are circumventing inefficient banking and currency controls at home, and by US cryptocurrency enthusiasts," Evans told AFP.
"The governments in those countries restrict the amount of money that their residents are allowed to transfer abroad through the banking system. Bitcoin enables individuals there to bypass such restrictions," he added.
This could be a draw for investors, who even before the bitcoin rage were already hot on the real estate market in south Florida.
Nearly half of all foreign buyers of property in south Florida are from Latin America.
According to the National Association of Realtors, over the past five years, investors from Venezuela, Brazil and Argentina — in that order — have led purchases in this part of the state.
Bitcoin is bad news for money laundering
Bitcoin offers another advantage for some foreign investors: it lets them dodge US economic sanctions.
Evans cited the example of Venezuela, which imposes strict currency controls and is enduring runaway inflation that surpassed 2,600 per cent in 2017.
What is more, many senior officials in the government of Venezuela's President Nicolas Maduro have been hit by sanctions imposed by Washington, which considers his administration a dictatorship.
Evans said there is also a lot of interest in bitcoin among Iranians, whom he described as "doubly hit" with restrictions in Iran and international sanctions.
It is an open secret that money laundering fuels the real estate market in south Florida. But instead of hiding the practice, bitcoin could have the opposite effect.
The cryptocurrency "is a terrible medium for large-scale money laundering, because all bitcoin transactions are recorded in the publicly available transaction record known at the Blockchain," said Evans.
Although bitcoin has been associated with the drug trade and cyber attacks, Blockchain "leaves a lot of fingerprints," former Florida representative Jose Felix Diaz told Politico.
"So if you're using it for illegitimate reasons, the state and the federal government should have every tool at their disposal to go after you," Diaz said.
Last year, Diaz sponsored a bill-turned-law that includes bitcoin in Florida's laws for fighting money laundering.
Real estate agent Jay Parker also said money laundering via bitcoin is far from posing a risk because "the beneficial owners of the real estate are always going to be able to be traced." Parker said the fad of doing real estate deals in bitcoin could be as volatile as the currency itself.
"I think it's a gimmick. There's not much risk. The only risk is if the currency crashes before you can liquidate it," said Parker.
"I think the people that are using bitcoins to try to market their properties are doing it with the very purpose of getting you to write about it, getting their properties exposure," said Parker.
