You are right, some people are to blame for their loss but rather they will blame btc instead, when they will buy in when the price is high and then not have the patient to wait for another price rally, they will sell at the slightest price dump then blame btc for everything, hope people will soon understand this things properly.
We can all say that they are those people that doesn't actually know what will happen. They are not knowledgeable enough on where they put their money so when they are losing they will just go out saying it is a scam and all but it is all on them. Just look at those people that is here for a long time now, even though there are a lot of dumps that happened, they are still here and still getting profits when the price are like what it is right now.
