When I first joined the we had a reserve rate set and were earning % APR in MATIC.
Since then it’s undergone a trial of sponsorship rewards and the reserve rate was set to zero. I haven’t found any rational for the reserve rate cut, only the sponsorship rewards.
The motivating factors for joining the pool were essentially taken away. Now it seems, to get any benefit, we need to sponsor and perhaps have a little in the pool.
By restoring the reserve rate to somewhere around 5-15% (personally I think 10% is a sweet spot), this will increase the prize over time and perhaps make it more attractive to be a depositor.
