Some of those have helped me a lot to get where I am, I have decided on 50% as fair not only because of their support, but also because either

1. the rewards are low, so it does not matter to make a little less money

2. the rewards are high, so it does not matter maaking 50% less and considering it an investment

but I am open to try new things, will leave the rewards at 50-50 for some days and weeks and see how it goes.

thank you for making me think more about that
