It seems interesting, but I checked all the different surveys and nothings shows up so far for me (perhaps due to my location - Iran) or there's really none due to error (maybe other could confirm this). Hope more offer walls would be added in the future and also regarding the 10k Satoshi, here's my BTCitcoin address: 1Gm5K2H2fjD2oiTn4rWC5GwQMn2xMUBc5g
Thanks.
