One painful thing is that their developers act centrally on the project and decide what to do whether in favor of the community that is larger than them (just a board of 10 to 20). Even if I will invest in a project, I will wait until it gets listed on exchanges and then I look for its strength before I go in.
It's good strategy. If the project has good potential you can skip the first pump and participate in the second more powerful. Otherwise the massive dump will be visible
