I always treat ico as a trap that is use to hunt for animals.
In crypto it is a trap to hunt for investors.
A nicely polished ico can lure more investor into its trap.
Making a good trap is the key for any successful ico.
Also investor are getting clever, ico founder need to make better trap so that more people will fall for it.
And I believe good salesperson make a better trap compare to ordinary nerds.
To make it work, they need strong marketing team.
