Have you noticed that whenever someone complain or there is an incident of scam they is always a role that was played by the person in that happening, either they failed to be security conscious or they were totally ignorant, and when you look at it the scammer never forced them to comply, this people willingly fell for their trick (Now to be clear I'm not saying scammers are right or saints, I'm pointing to the fact that we are responsible for ourselves, so enough of that shitty excuse, yeah the Internet would be a safer place without scammers but there are here, so deal with it)
Just know that scammers are very intelligent, there are many ways to scam people, and that is why sometimes if someone gets scammed, I don't normally blame them too much. Another reason people get scammed in this crypto space is that the crypto space is very large, there are many ways to make money from crypto, so some scammers use this excuse to scam people, and one thing about this is that both knowledgeable and uninformed people fall victim to getting scammed.
Just that people with the knowledge are kind of limited when it comes to getting scammed, so now when the thing is that we should have the knowledge of where we want to put our money so that even another stranger comes from nowhere claiming to tell you about something like that, you will find a way to deal with that without much stress, but if you do not have the knowledge, that is where they will easily scam you.
There are lots of crypto investors that are well educated, have a good job and a higher level of exposure than even most scammers, but they chose to enter into the crypto space irresponsibly and they inevitably get scammed and at times lose huge sums of money or even life savings. Last bull run there was this Elon musk swap scam that was on and someone lost 10 bitcoins to it and even other cases where people have gotten scam through crypto ads or crypto exchanges that shut down and all this would have been prevented in a way.
This is because the crypto space is an open place where everybody can come in and do what they wish to do. It is just that you will be the one to be in charge of your funds; everything is at your own risk, and most times those rich people lose more in crypto because they can invest in it, and they won't have much time to study it looking at the market movement because they are busy doing other things out there. However, for the shutting down of exchanges, I will not blame investors. If an exchange gets a problem and shuts down, I think the problem is not from them; it should be from the exchange. Although we are investors, we just have to be careful with where we are saving our funds.
