(Reuters) — Japan’s army of retail investors, no strangers to high risk bets in the past, have emerged as a major force in bitcoin’s spectacular rally, now accounting for an estimated 30-50 percent of trading in the cryptocurrency as it spikes to record highs.
Once skeptics, Japanese retail investors have been attracted by the digital currency’s volatility and inefficiencies in pricing that create opportunities to make money on arbitrage between exchanges.
“When I first heard about the bitcoin a few years ago, I thought it was a fraud,” said Yoshinori Kobayashi, 39, a former stock trader who took up bitcoin trading two-and-a-half years ago.
“But I tried it out after I had come to know some people making money on it. I bought it at 60,000 yen, which quickly become 80,000 yen and I started to regret I hadn’t started earlier,” said Kobayashi, who believes bitcoin is on a long uptrend but took some profits last week.
The spectacular surge in bitcoin, up more than 16-fold this year to above $17,000, has drawn comparisons to the 1970s gold spike or Japanese shares’ rally in the 1980s’ go-go era. Both of those delivered massive gains to Japanese retail investors before plunging sharply.
Statistics on bitcoin and crypto-currencies are patchy because their trading is unregulated in most countries.
According to data compiled by Jpbitcoin.com, a Japanese bitcoin website, yen-based bitcoin trades reached a record 4.51 million bitcoins in November, almost a half of the total of the world’s major exchanges of 9.29 million bitcoin.
