As far as Bitconnect is concerned, I can understand why people were "fooled" just by considering the naiveté of the members in several coin and exchange Telegram channels. Some have no idea what the purpose or value of the cryptocurrencies they are "trading". They are only looking at the possibility of making money. They do no research; don't seem to even know how to. And once one of these "noobs" (not meaning to use that term in a derogatory manner - I think of it as the same as "newbies") chooses a favorite coin, they see nothing else but the ups and downs of price. It is really sad. They need to research what cryptocurrency is, what solution is being solved, who is behind the organization, etc. All the considerations that will determine validity and risk.
