Hey @StefanGeorge - acquisition cost is usually equal to or slightly more than the gas costs when there is sybil resistance in place (users want to feel like they made a profit from doing the actions).
When we ran the campaign with Aave, they were awarded with aUSDC as opposed to AAVE, so many kept their tokens to receive the free interest. Can get the exact data for you for this particular campaign if you’re interested. Still waiting on the data back from the Matcha campaign as there is still one more week left.
We could quite easily incorporate money streaming as blanket vesting(Sablier or Superfluid) to get users contributing afterwards and involved. This will ensure users can’t just liquidate right away. Let me know if this is something of interest.
My suggestion is to involve all 3 products since that’s where the real value is. Interacting with Gnosis Safe is likely the easiest and the most lightweight and would love to bring more education to the rest of the Gnosis ecosystem.
Let me know what you think!
