I manage strees coming from Bitcoin volatility by having enough knowledge about its market fundamentals.  Knowing the fundamentals can at leaset secure us that Bitcoin will eventually goes up, this crashes are just a temporary event Bitcoin will push through these difficult times.  Besides, I only use the money that is free and never used the family budget for buying Bitcoin.  Probably that is the reason why I am not stressed when Bitcoin goes up and down, I only use the money I can afford to lose.
