Nevertheless, it was a fake news, on the bright side, we witnessed $30k after. But obviously short day traders could have taken advantage of it and speculate and then sell at that price, pulling down the market to the $28k'ish.
Even with fake news, as long as the market is already on a bull run, it won't mess things up much. The bullish trend will just keep on rolling. That ETF thing has been making the rounds in rumors for a while now. I reckon those rumors help fuel the bullish sentiment because people are used to hearing about it. In the long run, it could have a significant impact on the market.
But speaking of hype, it usually hits harder when the rumors are fresh and exciting. You know how they say, 'sell the news' because by the time it's official, the hype might have worn off.
