As far as I know there are already:
- E-commerce market = XMRBazaar
- Freelance market = monero.jobs
- Donation and Stream = Xmrchat
But i still didn't see a subscription service that can become alternative to Patreon. What make Patreon interesting is that you can make a tiered service for your supporter and plus you can give exclusive content that only the member can access. Does anyone know such service exist within the Monero community?
UPDATE:
Because there is few information available on the service with such concept thus born OpenFans, a membership platform for people that want to monetize their content made by @nolan.
