There are many more scammers that walked away freely in crypto space since 2017, they are living a good life that people they scammed never lived, I hope one day justice will be done, there is nothing to worry about, GOD is not dead I believe
Actually justice has been served, it's just that sometimes it can't be seen because scammers can't be punished directly like people in real life, so don't worry too much about them, as long as you always do research to avoid them.
