But to understand the dynamic that led to this year’s depressing year for crypto, we actually should start a few years before 2018. In bitcoin’s early days, Mt. Gox was the go-to service for handling transactions. Then, in 2014, it halted transactions and slowly copped to a crypto-hack to the tune of $473 million, the biggest hack of its kind at the time, and it gave many people pause. But it was still early enough for people to believe that the blockchain system was still getting all the technical kinks out.
Very generously our tweeter credits another crypto fanatic for the remarkable analysis, who had drawn up his own chart just days earlier:

Polkadot (DOT) turned down from $53.87 on Nov. 8, indicating that bears are selling at higher levels. The price has dipped back to $49.78, which is likely to act as a strong support.
