The 0.20% is if you win no prizes at all. On average including prizes, the EV on an annualized basis is around 3% right now. We are subsidizing some of the prizes currently, which is why it's higher than other HYSAs. In the long run we will aim to match Marcus and Ally, which right now are at around ~1% but go up or down depending on market cycles.
I appreciate the response, I've got a few remaining questions that perhaps you can shed some light on:
- Is that only for the average or also for the median?
- Is the data published anywhere (would love to see distribution curve)?
- Are the calculations assuming someone is saving every week? Or has it also been tested monthly / bi-monthly?
- When someone gets a "windfall", do they keep it in their account or do they withdraw it? (i.e. no longer savings but spent in some sort of celebration)
- Is this using an actual random number generator in which case there will be long-tails of people winning much more as well as losing much more? Or is there some sort of engine that ensures everyone gets something?
- This is the average. Going along with your second question you can get a sense of the distribution by looking at the payouts and probabilities in the official rules (https://www.withyotta.com/official-rules)
- It's purely probabilistic so it doesn't need to be tested. It's just random number math.
- Wins are deposited into your Yotta account and are immediately available to withdraw if you'd like
