This is the reason why we always told never to trust other people better to trust ourselves.
That might cause excessive fear and might make a person extremely paranoid well I guess, there should be a balance, every once in a while we see some new tokens/coins getting 10x or 20x in real just after listing, so it pulls our greed and makes us question, are we really not missing out on making great profits?! But yeah, one should always be conscious and aware of what they are doing!
