Why has staking rewards been reduced drastically? Was about 5% a month now it is 5% a year?
Not sure, but my staking is still around 4% as it has always been since the start. After I've started the pool this has not changed actually, and the total forging % is also relative stable slightly above 60% of total HEAT cap.
How much HEAT do you have? Are you sure that your node is still properly in sync?
Yes my node is up and running 24x7, is properly synced, sending you pm with some of my details to lookup.
