It depends on the traders, no matter how often I check bitcoin price but if my main purpose is for long term hodling then I wont do panic selling. Checking bitcoin price more often will help traders to decide what to do. Panic selling usually done by beginner traders who are afraid to lose their money, they hope to make profit in short time but they are not ready with the fluctuation.
And no matter how often we check the price it won't change any way.
And if you're long term holder the price doesn't matter because you're not selling it. However, checking it every minute is a real struggle tho as we wanted to see if our coins doing, checking doesn't mean we want to sell it but rather just observe the market.
