So is that a problem for you? because they investors always use their personal money in investment so that other people have no right to intervene in it, because every mistake they make is a risk that they have to bear alone, unless you are willing to accept the risk they feel.
Too bad that there are some people that uses borrowed money to invest. That's not really a good style of investing but if it's their own money then that's better.
Because they have no one to be pressured of paying and they can just do whatever they can with their money and be careful to what they buy.
