Our world is so severe that it’s necessary to learn to laugh in general. Laughter is the best medicine. Nowadays, traders are familiar with all roller coasters that BTC can perform, so they are calm when see sudden decrease of BTC on 20K-30K and just prepare to invest more because they know: BTC will definitely increase again and make new ATH (need only to wait). Same cannot be said about some alts and tokens that may dump for ever.
