Without any doubt those managers are making things perfect in the bounty section. However, there is also some others who are getting things done perfectly. Such as Atreezy, ryjin, and newsilike. Recently I have getting involved into their campaigns and they also have good projects on board.
Mostly we should follow all of them so that we can at least hit to top ICO projects of all time and thus getting us huge ROI for our time and efforts.
There is also one thing I have observed that, when we invest into project managed by the ICO team itself then it could be ambiguous one to join or not as the success is less for such campaigns. Thats just my thinking and experience. For newbies it could be gold.
