The biggest challenge in the space is everyone, including the experts, has a lot to learn. There are so many different disciplines involved, everything from economics, to game theory, to software engineering, and there are so many different philosophies in play to all those things. A lot of ICOs are people who have maybe good intentions but they just don’t have the experience of years of building those things, so they’re repeating a lot of the same mistakes, or they’re throwing tokens into things that don’t need tokens, or they’re making things decentralized that don’t benefit from decentralization.
