It's true that what makes this strategy difficult is because it's difficult for us to trust other people. And sometimes there are differences in the interests of each person which can lead to conflict or something like that. So it's better for us to stay focused on investing for ourselves and with our own capital. We can start with a small investment and gradually move on to a larger investment. Don't rush in pursuing success. It's better for us to enjoy every process and slowly we increase the assets we have.
The thoughts of every individual is different from others so when two or more people are involved in mutual business or trading then there will be lots of conflicts between them.
I think it will be better to use our own money rather than using mutual money because in this strategy you will be dependent on other's decisions.
I think one should be free to take decision and other benefit of self investment is that no will be there to blame you if unfortunately you take some wrong steps.
