Bear with the metaphor pls. It's relevant I swears:
- An arcade allows you to trade in dollars for tokens.
- Whether it takes 2 tokens or 4 tokens to play a "game" doesn't really matter
- These tokens are roughly pegged to USD, but you aren't playing the game hoping that these tokens appreciate.
You trade your USD to participate in the game. Any appreciation of Nano over time is more of a side-effect
That being said, is there anything particularly illegal around an app that
- Asks you to pay N dollars for X Nano.
- You participate in the app, either spending/gaining Y Nano over time.
- These Nano are verifiably yours to do with what you want. So, you stand only to gain if the app grows in popularity/reach
- At some point in the future, you know that it is possible to convert your Nano back to USD (for hopefully a better exchange rate than when you previously "invested")
Is the app considered an exchange if you take USD for Nano?
What if the app never claims to give you the "best/most recent USD-Nano" rate, but offers it at a massive discount?
Food for thought?
