Then nothing, it's ironic that after 12 years of Bitcoin's existence and the quite explosive increase in price and adoption, people still come to focus in when the price dips or slips into a bear market. At the beginning of the 4th quarter of last year Bitcoin was less than $10k and it is currently above $40k, if you hold some you can use this opportunity to buy some more at a discount, if you do not hold some, you shouldn't take interest in the market movements as the holders understand its risk and potential (except of course you wish to buy).

There is always panic anytime the price dips, especially by more than 10-20%, this does not indicate a bear market, and if it does a lot of holders are not bothered.
