You are right about that. There will be a period where they will require pioneers.
I thought of a different but related scenario too. What if the investor collects a few friends to bump up his ratings, then wreaks havoc with real investors' funds?
Here the Broker comes in, the manager can't just go away with people investment, there is a ledger, which is the broker, the manager always has to have an amount equal to the value of his tokens, people don't just give money to the manager, they BUY the manager's tokens from the manager, for example, a new manager starts with 1000 tokens, and each is worth 1$, for that manager to be listed, he needs to give 1000$ as protection, which is the entire value of his tokens, then comes the investors and buy the managers tokens, one investor buys 200, the manager now has 200$, others buy 150, 250 and 400 tokens respectively, so now the manager has 1000$ to invest whoever he/she wishes, but the manager can't just run away with that 1000$, because there is 10004 that he gave up to be manager, so all that money returns to the investors, that is why manager has to have the value of the token he represents to return to investors for them no to lose their money.
