I can't blame people who are hard to trust altcoins now, especially with what the community has seen last 2017 with scam ICO projects. That's why you have to be skilled in seeing which project is legitimate or not by checking if they're hitting their roadmap and signed/sealed partnership with multiple blockchain companies and not just verbal nods. You can still definitely trust altcoins but you need to be very patient in doing your own background research with the team behind the project you're gonna invest on.
