Odaily News Coinbase, the largest cryptocurrency exchange in the United States, is targeting potential demand from Australia's growing self-managed superannuation industry. John O'Loghlen, managing director for Asia Pacific, said the exchange is developing a service targeted at the segment. The latest data from the Australian Taxation Office shows that such portfolios account for about a quarter of Australia's $2.5 trillion superannuation system, with A$1 billion ($664 million) allocated to cryptocurrencies.
