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.
Unfortunately you're right about that, majority of new investors now would like to earn quick thats why even they dont have enough knowledge about the investment and only aware of basic information about it they tend to invest regardless how risky their decision is.
Then if something went wrong no one is to blame but themselves for not conducting their own research and for not being patient to learn and wait for the right timing on when to invest.
This is nothing wrong that you have explained about newbie investors. According to me, patience and research are two weapons that an investor needs in order to win the crypto war. Before investing into any coin, one has to be highly confident about the legitimacy of the coin and its bright future. This confidence can only come from a deep and proper research. Otherwise one will always be vulnerable to wrong decisions.
