they're just like the storm; today for the bullish and probably tomorrow for the FUD, right? we have seen much of these hypocrisy among the public figures and for this, i won't give a damn shit to this regardless of she be a journalist. Most of them aren't bullish on a long-term according to history and for this tweets to be announced publicly on a short-term we have to wait for long-term to applaud. Hope to see her on a bullish long-term with Bitcoin.
I think you're on the right track with your analysis, and the fact that some people suddenly change their minds is mostly related to the feeling that the BTC is likely to explode again - and why fight the wave if you can ride it. The media behave similarly to the end of 2017, but let's just remember how many times they wrote negatively about BTC during 2018/19 and even a few months ago when we had a sharp drop of as much as 50%.
I have to admit I read some very interesting comments below her tweet, but generally it all comes down to this gif
