Now one bitcoin enthusiast has handed over more than 800 bitcoins to buy a two-bedroom luxury villa in Bali, Indonesia.

The sale took place on Feb. 19 via BitPremier, a website that calls itself "the bitcoin luxury marketplace." Sellers list properties and other goods on the site, which prices them in bitcoins as well as traditional currencies. When an item sells, the site takes a 5% commission, paid in bitcoins.

The villa's buyer is an "early bitcoin adopter" who has chosen to remain anonymous, said Alan Silbert, chief executive of BitPremier.

Ronny Tome, the German real-estate developer who listed the still-unfinished property last fall, described the buyer as "an early miner," referring to the computer process of generating bitcoins.
