it's a bit insulting to credit libra with sparking bitcoin's bull run.
Crypto news always pick some stupid reasons to explain Bitcoin's price changes, because they only care about making stories that would generate more traffic. And they seem to be quite successful at that, because I see so many newbies repeating the narratives created by crypto news sites and blogs. It's kinda ironic that so few people want to actually think critically in crypto community, considering that Bitcoin was created because of distrust towards other people.
I have seen so many people after Facebook announce their intention to lunch the coin initially without specific time frame start investing in bitcoin because of the believe and the mentality that this will be a trigger for the bitcoin bull run, and the coin itself might not be the trigger, but the action they took at that time to choose to buy is what actually may have led to the price increase and then they associate it to Facebook.
