Bitcoin Mining or Scams

I've been trying to understand the cryptocurrency world for almost a year now and yet I still feel like I barely know anything about it. I've tried everything from purchasing mining, running my own mining rig at home, cloud mining, browser mining and applications which mine cryptocurrency. I've slammed my face on the floor and I still got up trying something new. Everything seem to be far too little for the hassle which they still are but for someone to see between the lines and actual try to see the light at the end of the tunnel. So I ventured down the rabbit hole and quickly found so many scams and all without anything to stop them from running them. I've grown up in a family that were pretty honest for the most part, not trying to run scams on anyone without any sort of regulations or ethics on the part of the people running the scams. So I ask myself how can this be legal? How can people get away with running a scam online and have no repercussions. Now I'm just one person but I've been slammed out of about $180 and it was my own fault for thinking that anyone carred or even wanted to care about my financial situation. I trusted people at their word that they wouldn't screw me over and yet they still did. Now you would think that I learned my lesson but I haven't, I'm learned some but still a newbie if you ask me but I'm learning the hard way. Has anyone else out there been scam'd out of there bitcoin?
