When we announced the lowering of max bet profit a few investors added almost 1,000 LTC (maybe deciding that it's a good moment to invest) and existing investments' share shrank.
From that moment site profit increased a bit, but here's the thing: investors that had certain share in loses when the bankroll was going down had smaller share in profits when the profit was going up. The same happened with my investments, they lost disproportionally to site profit changes.
This is why dilution fees can be a good idea. Dilution fees would have at least spread some to the existing investors who got crushed and then had their shares reduced by the further investments.
