That's a very good question, will we and what will it look like.

A professional trader is like a Whale by Delegation and Free Lending, wouldn't you agree? His job or 'faculty of work' would be to increase the wealth of others, his benefactors. By doing that the broker/Pro-Trader can create a fair or even great profit for himself as well.

So a smart Pro-Trader will always be of use to a system that supports his skill and greed. The difference is, this time around WE the people are the BANK, because by the power of ourselves (our keys) and BlockChain FiNTech/DeFi we can employ the professional trader directly ourselves. In some way, we already do that with 'Curators'.
