which person is telling BTC is useless those people really dont know under value it and they want to destroy the market every time,those people need to do the things there doing, any field mislead people any where we can find.
This is the only thing that we can say about them because they must not be aware of bitcoin real value and importance. It can be say as lack of knowledge and information so if they must have knowledge they will accept the bitcoin as currency, investment. They really need proper guidance and information to share with them about bitcoin so they will like bitcoin and they will be agreeing to use it because bitcoin is life changer and future maker not a useless thing.
