That's the worst situation, but usually, scammers use the lack of knowledge as a way to promote their "guidelines" or "guidance", and then people get rugged.
The first rule is to do things yourself, you will be right or wrong, but it will be you, not somebody else.
Sometimes, people with good knowledge also fall for scams. Scammers are always inventing new methods, and some of them actually work. Even people who have been crypto space for a long time fall for these traps. I was scammed a few months ago even though I thought I would never fall for scams. I was scrolling social media at late night and I received a phishing email. I didn't notice who is the sender and I connected my metamask wallet to a phishing website which drained my entire metamask wallet. Another Legendary forum member was scammed in the same way. Do you think it's because of a lack of knowledge? In my case, I didn't pay enough attention to the website before I connect the wallet even though I know how these scams works.
Perhaps this is more of my reasons why I say bitcoin is risky and it's not guaranteed that one will succeed with bitcoin even after observing all of the investment methods which we advocate for, perhaps success can not be quantified with the amount of bitcoin one has accumulated over the years but his success rate at which he makes use of one of the Sustainable bitcoin withdrawal methods which JayJuanGee also talked about in one of his threads, which may not also be a real success as on whole time of investment could be whipped out in less than an hour of encounter with scammers.
Perhaps being careful is not just enough but also educating ourselves with the right knowledge regarding scams, phishing links etc is very important hence to protect us a little bit more as the internet itself is not a safe place.
Regarding scams and hack attacks I have once urged JayJuanGee to include security related issues into one of his writings as having to educate on every other part of bitcoin and leaving the security wise of it seems too left out IMHO.
