Narrowly defined platform tokens refer to exchange platform tokens, like BNB; broadly defined platform tokens refer to ecosystem underlying assets, such as (strongly manipulated) public chains; Bitcoin belongs to the underlying asset of the entire crypto space. A lot of people become more optimistic the higher the price goes, even showing off buying at high levels and continuously adding to their positions, just because the price is higher now... If you could understand the logic of platform tokens earlier, you should have bought and positioned at the bottom, rather than fud or fear at the bottom.
