You can't hold peoples hands, thats the price of freedom ie having the chance to make your own mistakes and learn from them.
You really haven't got involved in cryptocurrency until you get scammed at least once.....and then wise up.
Otoh, the wisdom of learning from other people's mistakes, is priceless.
Honestly, if you love to invest or love the risk, for a potential high reward, feel free to speculate. I'm also not trying to scare people to be conservative and lose opportunities, either! I'm not sure which frustation is worse, tbh, and I've felt both. But do so
with your own judgement.
