Take a deep breath: Bitcoin now represents 1.3% of the world's currency, with a market cap flirting with 1.7 trillion dollars. Yes, you read that right. A small piece of code born in 2009 has made its way to the same table as heavyweights like the US dollar (20.9 trillion dollars) or gold (20.2 trillion dollars). We may still be a long way from flipping the table, but clearly, Satoshi has set his napkin down well.
