I think im out of that shit, bitcoin just lost my trust it could have been something what changes the world but now I see another idea doomed by man´s greed.
I think that's the wrong message to take out of it. Bitcoin is valuable. Scammers are going to try to steal it, like they will try to steal anything else of value.
The thing to learn here is to be careful who you trust. If someone isn't willing to prove that they are mining, and cannot demonstrate that they are solvent then it's really not a good idea to trust them or to trust that they aren't insolvent.
