A good feature is to make the interaction between manager and investor a trustless association, there will be no scamming and a reputation system, so common people that don't know anything about trading and investing could simply give money to a professional of their choosing and let him/her invest, so the profit is shared; A con to this project is the use of a broker, because we are in a blockchain environment, their shouldn't be a middleman, the same concept of trustees should be applied here.
