The pseudonymous bitcoin analyst and the creator of the bitcoin price model called stock-to-flow (S2F), Plan B, called the last three months of bitcoin prices correctly but the analyst’s “worst-case scenario” forecast missed the mark in November. Despite the recent bitcoin price drop, Plan B still seems confident bitcoin’s price is “on track towards $100K.”
