It's a financial market, there will always be days where the market will dump it can't just keep pumping, after a huge pump like that a correction was always going to happen, although some people believe it dipped because Elon Musk said bitcoin was kind of over priced, that was what led to this huge $13k dip, but no point panic selling  cause bitcoin will definitely recover from this dip, the bull isn't over yet, I would advice you still hold on to your bitcoins,$100k is still possible this year.
