hmmm, i have not seen any bonus codes last month(since you introduced it for the first time)
Also will be good to announce that your service mostly focused to North America users... Because another countries and regions users just stuck at 3:1 faucet ratio and left...
I second the promo-code issue. Would be nice to have few extra sats, like 5K once in a while. Maybe some random PM's with codes? I bet it will help to promote this site.
About ratio, I think you are exaggerating, oferwalls are providing lots of surveys, check them every fifth claim or twice a day and eventually you will get some. If there are offers for my country, there must be more for others as well.
Keep up the good work bitgames.io
