I don't think anyone can predict the future of bitcoin either good or bad, but I am sure if the future of bitcoin will be good because there are still many people who believe and use bitcoin for their investment in the future so it is likely that the future of bitcoin will be bright someday.
I also agree with you that no one knows that bitcoin will be good or bad going forward. Because I have a friend he saves some bitcoin and he sells when the price is 300 million and immediately he is rich. But I believe bitcoin will be successful for the next needed in the present
