The interest you pay is lower than inflation, meaning that I am giving you money to buy the chance of winning a big prize.

You can genuinely think that you will be helping the world, I am not questioning your ethics because I don't know you.
But I don't agree with you. I fundamentally believe that what you are offering is, in aggregate, bad for the world.
This is not targeted towards those capable of shirking all dopamine feedback loops and doing massive amounts of research in order to maximize returns. This is targeted towards your Average Joe.
Edit: Editing to also say that enticing you to tune in to look at weekly results doesn't help I guess and makes it feel like something you could get addicted to and emotionally frustrated when you don't win? In that sense maybe not good?
By your definition, pretty much anything would be considered gambling? A generic savings account might return less than inflation and you get nothing else for it. A checking account earns 0% and you get nothing else. Is that gambling?
