You don’t send your 3000 ADA (minimum) anywhere to vote. There is a small transaction fee (~0.17ADA) to generate “voting power” in the Catalyst app based upon how much ADA is in your wallet at the snapshot before voting begins. No one knows how large the rewards are until voting occurs, because it is a reward pot that is split amongst all voters (weighted based on your voting power). Last round there was about 500M ADA (voting power) registered for $35k, which amounted to about $0.60 worth per 8k ADA (which was the minimum last round)…so, not much. 62k ADA would have gotten you $4.50 worth of ADA in voting rewards. There appear to be many more people participating in this round, so you might get even less. What made it even more confusing is that people’s voting rewards were bundled along with the regular delegation rewards when they were paid out and, since the amount was so small, many people didn’t think that they received their voting rewards when they actually had.
