“BitInstant is just one of several Bitcoin startups attracting funding from established venture firms and investors at a valuation in the millions. Coinsetter, a New York startup working on a foreign exchange trading platform for Bitcoins, recently raised $500,000 led by Tribeca Venture Partners and SecondMarket at a valuation that we hear is in the ‘low single-digit millions.’ Coinbase, a startup that provides a digital wallet for Bitcoin transactions, has raised $600,000 to date from Y Combinator, IDG Ventures and others. (Cameron and Tyler Winklevoss, the twins who had a disputed role in the founding of Facebook, are also big Bitcoin investors.)”
