According to Coinbase, the total value of all Bitcoin is currently about $3.5 billion. This is a tiny, tiny market for "Fortune 500s and Wall Street" and is equivalent to the value of a single (smaller) mid-cap company. Even at its peak, the total value of all Bitcoin was only around $14 billion.
Daily Bitcoin transaction volume hasn't exceeded $100 million since July and has been as low as $33 million recently[1]. For comparison, daily volume in the FX markets exceeds $5 trillion.
Blockchain technology might be important but Bitcoin itself is about as interesting as the Burmese kyat or Gambian dalasi.
