If a coin introduces a completely new technology that enables a different function and is sustainable in the long term, does it have the potential to be a worthwhile investment?
Most of those new projects honestly just have some new innovative roadmap designs and some interesting ideas so that they can attract their investors with it. You cannot just simply rely on that because that's not enough nowadays and probably they just copied what they were saying in their roadmaps and just simplified or they were just lying about it. This is their deception and the worst of the matter is, that you only find that out too late when they start to delay what they were saying in those roadmaps and you cannot do anything about it but wait and hope for progress when you already invested your money.
Understand that it depends on the ability to implement what's in the white paper. Rather than just shouting slogans.
