Those investors that are too impatient are those who are just after the easy money, those who don't value much the time and that they don't care about the project at all, but what the project can give profit to them, so this kind of people too are those can easily get scam as they don't think well before they will invest.
This is what often makes many people easily trapped into a scam project where they just want to get money or tokens from a project without judging whether the project is good or not are people who are very easy to be influenced. So for me personally it is very necessary for investors patience before deciding to invest and make decisions.
