This is a great Idea. Myself host a limited and secure club called Arcane Market, whee you have to apply and answer some questions for acceptance. The criteria could be high, as we're trying to build a community with experince and long term knowledge. I'm not sure if you're familiar with discord, but check it out! https://discord.gg/KHRbWbbYKh

Ps. As an entrepreneur and software engineer I'll take this idea, sound awesome! I'll see what i can come up with ;)
