Likewise, @decentralion working on this approaching 2 years full-time, is worth more than $412. You’re confusing Cred and Mana scores with the $ budget that has been put into the CredSperiment so far. Which is exactly the risk of tying it to fixed exchange rates.
How much has been payed out is just an arbitrary number that has no real influence on how the SourceCred algorithm values your contributions. When the budget is there to pay people more, your mana and $ equivalent will increase accordingly. For example as would happen with the $100k airdrop idea.
