Is it because cryptocurrencies are not regulated the way it suppose to be or this is just how the world is?.
it is just how the world it. also, it is not about regulation. FIAT is regulated but you can still see tons of scam relating to it. one of the reasons why scams in cryptocurrency are rampant is because it has value just like FIAT and even if bitcoin or cryptocurrency is regulated as long as it has value scam relating to it will continue to show up.
