There are many fake gurus out there so be careful on what and who were listening. Predictions are just speculations  of other people so there is no reason for us to bother it. There are a lot of people who became hyped before when they hear or see a post about a certain prediction and it is the reason why their portfolios are now negative. I do not see any negative on predictions but make sure that you will rely your decisions just because someone created predictions about it.
