LONDON (Reuters) - Cryptocurrency firm Blockchain.com said on Wednesday it had raised $300 million in its latest funding round at a valuation of $5.2 billion. The round was led by DST Global, Lightspeed Venture Partners and VY Capital, the London-based company said Blockchain.com offers digital wallets for storage of cryptocurrencies as well as retail trading and other services for larger investors. Bitcoin soared to a record just shy of $62,000 this month as mainstream firms and investors increasingly embrace cryptocurrencies, leading to ballooning valuations of related companies. Blockchain.com said last month it raised about $120 million, with investments from Alphabet Inc’s venture capital unit.
