If ~$500 fluctuations aren't of interest to you, why are you very pleased that the price went up like ~$400 today?
You don't have to make yourself look tough. It's okay that you're afraid of what the market is subjecting you to. As soon as the price goes up, people gain confidence and start to think about how Bitcoin will take over, but as soon as it dumps, fear creeps in and you think about how you could have sold while the price was 10-20% higher a week ago.
One has to be a geek and true believer of the underlying tech to not give a damn about what's happening right now. The rest pays attention to the $$ value of their portfolio, which is all good considering that most people are here for the profits.
