You'll only get screwed if you don't know what you invest in, investing in something you don't actually know is far more than a blind investment. Pyramid schemes that were introduced as investments, trading, mining, etc. by these fraudulent people just to hide their motives are the thing that kills adoption most of the time for crypto. Let us all thank Satoshi Nakamoto and the people that made us realize what Bitcoin is today and the future that may comes.
Those who don't know about bitcoin and the cons of bitcoin only give negative sentiment which of course will lead early users to leave bitcoin.
I have often found negative sentiment towards bitcoin that says that bitcoin is just Ponzi husks, a pyramid scheme that only does harm.
That's always the thing, they leave thinking it's nothing like what they've experience from these fraudsters. Some people I know that asked me as well about Bitcoin after they invested on a pyramid scheme and got scammed have been on that situation, they received messages from unknown people on social media and offers them passive income doing nothing but in the end the money got rugged. This totally hinders adoption in the process.
