The US Securities and Exchange Commission / (SEC) is examining an application from the Chicago Board Options Exchange (CBOE) which, if approved, could grant the company a coveted BTC ETF license, and bring new waves of institutional investors to the BTC spehere.
ETF approval is an important thing, because it will really introduce bitcoins to various types of investors. It will also make sure that investments are safe and legal. It is also pretty likely to lead to a huge bull run, because of all those new people investing into bitcoin, but I don't think we are going to see the approval soon. Winklewoss brothers make two applications already and the second one was rejected yesterday, I believe. The govs are not ready for such steps, they want more time to pass to make sure that btc truly can be compared to gold.
