Nauru — $70 Billion

Nauru is the smallest island nation in the world with a shady past and an equally shady present. The island is northeast of Australia, and was mostly destroyed by phosphate mining in the 20th century.

After gaining independence from the British Empire, Nauru received a massive payout from Australia for the profits from the mining, which made it one of the wealthiest nations in the world. The money was quickly squandered by a corrupt and incompetent government with hair-brained schemes — one of their ideas to drive income was to make a musical about Leonardo Da Vinci which was an utter flop.

In the 1990s, Nauru transformed itself into a tax haven, but a very dirty one. Russia quickly took interest, as did al-Qaeda, and began laundering money through shell banks. Nauru didn’t verify the identity of it’s banking customers and didn’t ask questions.

Jakarta. Bitcoin is gaining traction in Indonesia, with massive growth potential as more people in Southeast Asia's biggest economy start to use cryptocurrencies, an industry player said this week.

Speaking on the sidelines of the Tech in Asia Conference at the Jakarta Convention Center on Wednesday, Jay Jayawijayaningtyas, country manager of London-based digital asset exchange company Luno, said less than 2 percent of Indonesians are currently familiar with Bitcoin. Education is therefore key in this early stage of Indonesia's cryptocurrency industry.

"One of our objectives is to educate Indonesian people and the market. So far, popular investment choices here are gold, bank deposits, or property. A recent survey showed that only 17 percent of Indonesians are currently invested in stocks. Cryptocurrency is even smaller than that," he told the Jakarta Globe.

Jay said people did not need to worry about the legality of cryptocurrency investments.

"Bitcoin is safe and legal in Indonesia, and our platform is also very safe. In Bitcoin, there's no such thing as money laundering, terrorist financing, or other things," he said.
