actually your question is a little confusing because you ask hold or panic, actually everyone will panic if you see the price of coins has decreased as it is now, especially for those who have a lot of coins, but for large investors will not panic because if indeed the top coin will definitely return to the price normally, so they will add back coins when the price is cheap
actually panic only happens to lay people who start trading and it won't happen for those who have longer flying hours they will relax even though there will be a little panic that's natural
