Good initiative!
However, I think the importance gradually decrease when more and more exchanges list bitCNY/bitUSD, thus it is not wise to pay lobbyist same amount of BTS all the time. That is to say, for top 10 exchanges, if one of them list bitCNY, it means a lot to us, but after 3 of them have listed bitCNY, we don't care so much whether the rest 6 exchanges list bitCNY or not. After all, even BTS is not actively being traded on all of them.
In my opinion, we should set a bounty with a upper limit, let's say 2 million BTS. The first top 10 exchange which list bitCNY will get rewarded like 500K BTS, the second 300k, third 200k, etc.. while the exchanges that are beyond of top 30 or 50, we have no interest.
