It's Rather unfortunate that developers don't really care about the interest of investors or holders of the tokens. Their major aim is to maximize profits and they are indifferent about ethics or the rightness of their actions. I think it's the responsibility of investors to research proper about a project before committing their hard earned resources into it.
It is and always have been the responsibility of the investor to choose wisely about the projects or coins, because the investors are the ones who will take a direct hit if everything goes down. It's unfortunate for those people who followed the hype without even bother to research it for safety checks and purposes, they invested on it just because it's what others does, but no, that's not how it's done.
That's is also why it's very crucial and important to make some research and study the market first before handing your funds to it, better be safe than sorry mate. Always buy now than later if you can actually afford it because we don't know when profits will starts to kick-in.
