I'm not getting stressed at all when bitcoin volatility attack, instead I became happy that it is moving either down or up. I like it when bitcoins price goes down because I get to buy more and later on profit more and I also like bitcoin price going up because of profits( who doesn't like bitcoin pumping Lol).

Almost everything in our world is both a source of stress and happiness so if you get used to it it will just be normal for you and won't affect you at all.
