As one friend noted, I was one of astonishingly few who neither called for a sustained bitcoin/eth/crypto crash nor a continued increase. I called for a temporary crash, and not an ambiguously temporary crash. I called for “a large drop that would bottom out in about April 2018.” Only one other person did that to my knowledge, Crypto Quantic, whom I cited him in the article just linked.
How did I make this call? Refer to the previous links. Nothing too magical. A combination of fundamental and regression analysis.
