But you are right it is pitiful for those who couldn't do their own research and end's up losing their investment because it was a scam project.
not just on those years you mention but new and scam projects already existed before the internet begun but thier hype only got stronger and bigger ever since cryptocurrency became live especially when cryptocurrency are on a hype trend . the feeling is bad if you will be loosing your hard money on these scam projects just because you'v been tricked . im sure that we all are experienced that bad moment but now im done with them , now i only invest on the legit ones and not on those new tokens .
