Those projects were indeed good and has a huge possibility to grow and be popular this year, and even might be the change to the crypto and digital world! Why? Those projects were simply innovation and improvement of prior projects and cryptocurrency system such as Ripple/XRP that was made for various digital transactions in which was being enhanced by Digibyte and Libra of Facebook. But still, there are no assurance that those would somehow be ever required and if those would gain strong community. Even current projects had difficulties building trust and image. Furthermore, projects still depends on the users.

Nothing to add. I've had enough of too good to be true projects that turned out a scam and had a huge count on my regrets.
