Japan's bitcoin craze could help the country's economic growth, research analysts at Nomura Instinet said.

"We estimate the wealth effect from unrealized gains on Bitcoin trading by Japanese investors since the start of [2017], and estimate a potential boost to consumer spending of ¥23.2 billion to ¥96.0 billion" ($206.7 million to $855.4 million), Japan economics research analysts Yoshiyuki Suimon and Kazuki Miyamoto said in a Friday report.
