No one nows. The market seems to be at a low now, but it can always drop further. In my honest opinion, the upward potential is higher than the downward potential, so I am holding.
Support. The market is not falling so much that panic starts. If you look at the graphics it is noticeable to the naked eye. Therefore, you can even buy more tokens, since the growth will be much stronger than all the falls for the current year.
