I have been tossing the idea of a cooperative based exchange run and owned by the community. There is alot of talent here and finance as well. I really am not a business person but it could be a way to pave a new path.
Heres a link to that may get some ideas flowing.

I am not a programmer just a computer enthusiast nor converse in trading or business practice.
Edit to add.

A cooperative ("coop"), co-operative ("co-op"), or coöperative ("coöp") is an autonomous association of persons who voluntarily cooperate for their mutual, social, economic, and cultural benefit.[1] Cooperatives include non-profit community organizations and businesses that are owned and managed by the people who use its services (a consumer cooperative) or by the people who work there (a worker cooperative) or by the people who live there (a housing cooperative), hybrids such as worker cooperatives that are also consumer cooperatives or credit unions, multi-stakeholder cooperatives such as those that bring together civil society and local actors to deliver community needs, and second and third tier cooperatives whose members are other cooperatives.
In the United States, the National Cooperative Business Association (NCBA) serves as the sector's national membership association. It is dedicated to ensuring that cooperative businesses have the same opportunities as other businesses operating the country and that consumers have access to cooperatives in the marketplace.
