Yes, that's how we respond to past failures, it becomes natural when we become skeptical of altcoins. But I don't think we should dwell on that fear, because that would be a negative thing in my opinion.
Don't dwell on that negative thing in the past but just learn from it. That's how life goes if you're into the market and mostly you're engaging with altcoins which are riskier than bitcoin.
Because surely if we have feelings like that will surely spread to others. We just need to increase our caution and learn from past mistakes.
Well, if you have that intention of spreading it to the others then you're just wanting to share that negative vibes to them and not to learn and share what you've learned.
