I am a newbie into cryptocurrency investments and I have tried how emotions would really push you to do things just to save your investments. And I was wrong for most of the time because I have let strong emotions to just take over for most of the time and I did not have any stop loss. For me it was wrong to just keep holding on to your coins because during times when market is bearish we will never really know if prices could go up or maybe could go  down very low. And that is what happen to me when I lost around 60 percent of the money when prices keep getting down. It was a lesson, now I did learn something, keep holding but be wise to set stop loss level.
