Ofcourse people are to blame for the actions they take both online or offline, crypto or non crypto space, but unfortunately nobody is willing to take responsibility for their actions, always looking for somebody or something to blame, just the way some people will blame John McAfee for their investment loss dah! the guy didn't force anyone to follow and do what he tweets or say, if you do so and loss money in the process you can only blame yourself,
Same applies to people who still engage and invest in hyip and pyramid schemes after the warnings for people to stay away, if you loss money to this sites, you can't blame anyone but yourself, the decision to invest was entirely yours.
