Coinbase Listeng marks latest step in crypto's march to the mainstream

Coinbase Global Inc, the biggest U.S. cryptocurrency exchange, will list on the Nasdaq on Wednesday, marking a milestone in the journey of virtual currencies from niche technology to mainstream asset.

The listing is by far the biggest yet of a cryptocurrency company, with the San Francisco-based firm saying last month that private market transactions had valued the company at around $68 billion this year, versus $5.8 billion in September.
