Dear Karen,

I can tell you're very bitter about Bitcoin. I recommend you consider another logical fallacy in addition to groupthink known as "escalation of commitment." This is the fallacy which makes you feel compelled to keep grasping for ways to mention Bitcoin in an effort to reinforce the previous convictions you've "written here over the last several years."

Another fallacy to keep in mind is "confirmation bias." An example would be a paragraph that contains only news that has been selected and interpreted in such a way as to merely validate one's preconceptions.

Of course, the irony in all this is that the only real "groupthink" going on in regards to Bitcoin is the very conclusion of your article last week that ~ "the blockchain is the real innovation and doesn't need Bitcoin." This is a perfect example of groupthink among traditional bankers who are simply repeating a manta without taking any effort to understand how a blockchain actually works.

I probably won't bother reading any of your articles in the future, but I do invite you consider that it's really not too late to learn about Bitcoin and perform a "pivot" of your own. I can guarantee that no one will hold your previous declarations against you because, frankly, no one has ever cared about uneducated opinions.
