You are right with your first sentence, don't invest too big sums.
But there is also a difference if something you invested in just did a bad job or mismanagement... or if they lied and stange things happened.
And of course every investors can blame them about that. It's the same with big companys like VW.
So don't try to silence investors who lost money... especially when 10 big whales could just leave and all others weren't even asked!
I personally didn't lost much, because i diversify, but it's about principle and fighting for the right.
You're right, people have every right to voice their displeasure but at a certain point get over it. This is high risk stuff. If you make it in crypto there is no way you are not going to lose money on bad situations and sometimes outright scams. I'm still not certain where this one is going but I'm just not going to spend too much time groaning about it. I'll set it on the back burner and look for other investments.
