You'd be constantly worrying about this if you're a day trader and is trying to live off the margins. You knew the risks before you came in, you just have to live with it if you want to continue.
The "true believers" don't usually worry about these fluctuations since they trust that eventually adoption would become widespread and that it'll be used as currency.
Untrained traders usually have the same feeling, they are too worried about the market price as if they didn’t analyze that much because if you’re a good trader, you’ll just wait patiently for the price to reach your target and there’s no need to look at the market from time to time especially if you are a long trader. Though day trader are usually active in monitoring the market but not to the extent that even on their dreams they worry about their position, this should not be the case and you should be more confident about your trades.
