Hi @costanza, @silverstackeruk, valid questions and let me try to answer as best we can.
#1. What backs the airdropped tokens = curation, off site staking
#2. Where will the actual value and returns come from = curation, off site staking
#3. What if people list tokens at 0.99 = we buy them back, someone already paid us 1 hive for that token to be listed, so that's a 0.01 profit. (we have a buy back scheme and multiple methods of funding)
If you do the math based on Hive and a few random upvotes each month at our minimum buy-back it works out at approx. 11% to 15% apr. There's no magic beans here I'm afraid, just a different (may seem overly complicated) type of curation model with an off site income stream.
