Yes, the prediction is quite plausible because now the bitcoin position is slightly disturbed, a lot of factors affect the reputation of bitcoin, so many people are starting to throw their confidence in bitcoin. It will take a long time to get people back to believe in bitcoin.
I always laugh when I see series of predictions like this and what comes to mind is the question, how on earth can anyone know what the future is going to be holding ?
Obviously, they do it to gain attention. No one will ever have an idea what the value of bitcoin is going to be at the end of this year, next year and the next ones to come. Nothing is predictable, it is a volatile market, and we can get to see any surprises at any point in time. Predictions will either set you up for a very high expectation or a low one but just follow what you see and stick with it.
