The game isn't meant as making you profit though. Profit can only be obtained if you're small (sub-100 steem) or got in early (and even then it'll be hard).
I get your frustration, but this should've been clear to you from the start.
They made quite strange changes earlier on, including turning the 89% of all in-game purchases added to the pool into only 80% (Almost DOUBLING the amount of steem that's lost through each cycle).
I get your frustration, but for now I just recommend trying to make the best out of it :)
