My biggest fear was the fear of missing out (FOMO) and this very common in the industry but I'm glad im getting over it because I'm already willing to buy and hodl at every time I have the spare money to buy.
And the second fear was the fear of regret if there was a loss at my end because I've always known bitcoin  to be very volatile with absolutely  nothing guaranteed  in it, hence I always try to stay very careful while hodling a d that's why I don't joke with  risk management.
