I don't think that people will lose interest about bitcoin. Because bitcoin now is so popular and it was trusted by the users and i think that it will be more popular next year and future.
Based on the performance of bitcoin today, and based on the testimony of users and traders of bitcoin I doubt if one person heard it will not get interested, nor those people who are already a member of society of bitcoin will loss their interest about bitcoin. But i didnt set aside the factors that bitcoin has which makes some of its traders failed in their journey in bitcoin.
