Problem is the lack of regulation and transparancy in crypto. Some projects are completely legit and above board. like ETH and BTC. Others are more shady, like pump and dumps. Many ICO's have proven to be scams. Some projects dont name the dev team and even have fake profiles. Other projects struggle with the tech like ETN. Stick to the coins you know and love. Stick to projects that work in areas of personal interest. The coming years will see fewer shady crypto offerings and more quality.
