Double clickbait  . It is better to be more focused, OP explains the important points of the article and video, so that we can more easily carry out discussions and if there are things that need to be understood then include the link. That's more polite I think.
I also could not take the main points of the article and had to open the video for more detailed information. But it seems that I can understand the meaning a bit, so I'm just saying that Bitcoin is a high risk, so nothing is really safe, we have to be prepared to face all risks, theft, hacking, fraud, etc.
