I guess we cant stop calling it as an investment because bitcoin is all about volatility and the changing of its value from then on and on. Bitcoin was supposed to be a project created to solve the problem in our way of using fiat money on government and other stuffs like that but the idea of how bitcoin can be a good profit if we know how to trade and learn some skills like holding, staking and selling thats how we forgot the main goal of cryptocurrency and we only think of it as an investment for a good profit. Thats why I guess we cant stop calling it an invedtment because we invedt our money on it to gain some extra profit.
