A good developer can be hired to build a project, may not be aware of the final intention of the project team. In the end, the project turns shitty, the developers may not have control over the future since they were only hired. Simply put: Unscrupulous team will always birth shitty coin.
Now a bad team is unlikely to be able to raise even more money, since ico can not collect much, and it is very difficult to enter the ieo market you need to be a top developer.
