Sometimes when it happens like this it is no one's fault, the only thing to be done is to just keep calm and wait, every dip will surely rise up. To me in a case whereby it still goes dip I think I will buy more. Going dip is not a time to panic but can also be an opportunity.
Of course, we can keep calm and wait or even decide to buy more, but as a person who experienced the 2018 - 2020 bear market. I gotta tell you. It's easier said than done
At times, you would wait until your patience runs out, and you would end up selling the assets at a loss.
Selling Bitcoin at a lower price was definitely a bad decision. Selling off other altcoins at lower prices was a good decision because some continued to dip while others died a natural death and never recovered even during the recent bull run.
