First, you need to know whether it's an 'investment market' or a 'speculative market.' If it's about Trump coins, then it's obvious you listened to a bunch of narratives and went in with the mindset of getting rich overnight. So don't talk about 'what lessons young investors should learn'; you clearly went in to gamble, so don't stigmatize 'investing.'
Secondly, young people have plenty of time and passion, and embracing bubbles isn't a big deal. Going for Trump coins is also just a gamble. There’s nothing wrong with that.
Life is always a gamble everywhere, isn't it? Betting on schools, betting on college majors, betting on industry tracks, betting on the spouse you choose, betting on children, betting on houses, betting on milk tea shops, betting on franchises. Since it's all a gamble, don't think there’s anything wrong with gambling.
The biggest problems are actually two:
1. Can you accept the outcome of the gamble? Can you afford to lose? If losing affects your life, then you need to think carefully.
2. Whether you win or lose, you need to understand what this thing really is at its core. Don't get overly pleased with yourself just because you made money, thinking you're the best in the world. If you lose money, you should also know what you lost. Don't end up thinking that you just had a failed investment and lost money. If you can't figure these things out, then the experience is pretty much wasted.
Finally, the volatility of the speculative market is the norm; otherwise, you wouldn't have entered it. Isn't this what you're chasing? If not, wouldn't a bank fixed deposit be more appealing? You can't want both. The key is how you view this matter.
