Ahh i see what you mean. That’s a good question, I’m reasonably sure there is no bridge between those services but never specifically asked. Rich has mentioned in videos the AnyTask purchases are made from the open market so i don’t think there is any link to top-ups.
Even if it was however, that wouldn’t make any difference as now there are no rewards, top-up ETN would have been purchased from the Open Market anyway. So either way its originates with FIAT not block rewards or premine ETN.
Good question though, especially if the same middle man was used for both services.
