People losing their bitcoins or cryptocurrency in general is more like an endless loop if you ask me and that's because no matter the case or scenario they will always be instances where people make mistakes or where they get hacked and their coins stolen.
for me it’s because there will always be newbies or there will always be new information that some of us may not know even if we have been in the industry for a while now
also because hackers will always find new ways to hack people and there will always be sacrifices first before we learn some people will get victimized first because they didn’t know any better before we learn from them
