Canadian Bitcoin miner Blockstream joins crypto unicorns with $3.2B valuation

Canada-based Bitcoin (BTC) infrastructure firm Blockstream, co-founded by cryptographer and cypherpunk Adam Back, has hit unicorn status with its latest valuation at $3.2 billion. The company, which focuses on various Bitcoin-related areas — including operating as a mining service provider and developing renewables-based infrastructure intended to “green” the veteran cryptocurrency — has raised $210 million in its latest financing round, according to Canadian newspaper The Globe and Mail. Blockstream’s new backers, which join existing investors such as Twitter CEO Jack Dorsey, are the United Kingdom-based private equity firm Baillie Gifford and Hong Kong-based iFinex, the operator of crypto exchange Bitfinex.
