initial perception of stocks were that they’re safe than crypto/collectibles!

Dude I remember people in here loading up on Skillz and I just looked at the price went from $40 to $2… like how is that possible for a company that's growing.. like WTF, I'm down a little over 40% right now on my portfolio but betting on skillz is literally like betting on a shitty cryptocurrency that has no future… I thought stocks were way safer then crypto/collectibles.. but it looks like growing companies (all the stocks I own) are all getting wreaked since November… it feels like everyone that's not in the giant tech companies or energy is getting rocked.. why do we invest in smaller growth companies if they all just get rocked for no reason whatsoever!!!! Btw I don't own skillz, was just using it as an example
